5 Best 6.5 Grendel Uppers [Hands-On]

Maybe you want something a little different than the venerable .223 Remington/5.56 NATO in your AR.

What is a good cartridge that is a jack-of-all-trades? Look no further than the 6.5 Grendel!


Look no further…I test out 5 of the most popular 6.5 Grendel uppers out on the market today.

By the end you’ll know if you want a 6.5 Grendel (the answer is yes) and which one to get.

The Jack-of-All-Trades

The 6.5 Grendel has proven itself so far to be a great cartridge regarding target shooting and hunting within intermediate ranges. Its parent case is the .220 Russian, which it shares with the 7.62x39mm.

Unlike the 7.62x39mm though, this cartridge is built with speed in mind and drastically outperforms its cousin in ballistics and long-range performance.

With high quality, factory ammunition becoming more available, the 6.5 Grendel is a great choice for anyone that wants to push further. Offerings from Federal Premium, American Eagle, Hornady, and economical steel case ammunition from Wolf can be found at local gun shops and can easily be found online.

Lots of Choices

What 6.5 Grendel upper will fit your budget and your expectations?

I went about answering that question with 5 different companies that offer 6.5 Grendel uppers! All the mentioned companies offer different price points for the 6.5 Grendel ranging from $399 up to $549. All uppers tested had either an 18” or 20” 416R stainless steel barrel, and all of them were a “Type 2” 6.5 Grendel chamber.

The companies are as follow:

Testing in Hilly Western Pennsylvania

During my time with the 5 different uppers, I was able to do some accuracy testing to shoot groups at 100 yards and out to 400 yards.

If I could have gone further, I would have, but the fact remains that Western Pennsylvania is not amazing countryside for 1,000-yard shots. In my opinion, though, nearly a quarter mile can still show excellent accuracy capabilities for a rifle. All rifles were thoroughly cleaned before they were shot.

The lower that was used is a typical, forged T6 7075 aluminum receiver with a rifle length extension, using a LUTH-AR MBA-1. The lower parts are from CMMG, but the drop-in trigger is the Timney AR-15 Competition Trigger.

Its no over-exaggeration to say that the Timney is one of the smoothest drop-in triggers I have handled with a very crisp trigger pull, and short reset. This is an excellent choice for precision shooting at longer ranges.

All shots were taken off a bench using Caldwell Shooting Bags.

Timney literally sent me a Tootsie-Pop with my trigger. It was delicious.

The optic used for all 5 uppers was an ACME Machine 6-24×50 FFP with their TR-MOA reticle. I have used this scope with a few different reviews, and I can recommend this optic for anyone with a smaller budget for long range glass. 

ACME Machine 6-24×50 FFP

Ammunition used for accuracy testing was sent to me by Hornady. It consisted of Hornady Black ELDs in 123 grain and Hornady Custom SST in 123 grain.

As always in my experience, the Hornady ammo performed great and was consistent with shot to shot. It is relatively inexpensive ammo regarding match grade, or hunting grade ammunition. I tend to shoot a lot of Hornady ammunition in my personal 6.5 Grendel rifle.

Best 6.5 Grendel Uppers

1. ACME Machine 18” Upper

ACME Machine sells and manufactures just about anything that you could use to build or upgrade your rifle. They are a lower budget, bargain retailer that can sell a product at a surprising low cost, while still offering higher grade components like Ballistic Advantage, Aero Precision, Magpul, LUTH-AR, and their own line of products.

AMCE 18″ Upper

ACME Machine’s entry into the 6.5 Grendel market utilizes a Ballistic Advantage barrel. The model that I received had an 18” fluted 416R stainless steel barrel. The bolt carrier group is a fully nitrided system that uses a 9310 Type 2 Grendel bolt.

Mechanically, the weapon fed and fired flawlessly using a 5 round ASC magazine.


The upper receiver was an Aero Precision M4E1 and aesthetically provides a step up from the standard mil-spec world of forged receivers. This upper came with an included ACME Machine 17” free-floated handguard and phosphate gas block. To round it off, the upper came with an ACME Machine ambidextrous charging handle and phosphate 3 port muzzle device to tame recoil.

ACME Upper – 0.89 MOA at 100-yards

The Ballistic Advantage barreled upper from ACME Machine performed very well and shot under 1 MOA at 100 yards. The best 5 shot group measured in at .89 MOA.

After the barrel fouled, it tightened up more when I reached out to 400 yards. This upper was able to print a .74 MOA group that measured in at 3.1” at 400 yards. I have had personal success with Ballistic Advantage before, so this did not surprise me.

ACME Upper – 0.74 MOA at 400-yards

2. Atheris Rifle Company 20” Upper

Atheris Rifle Company produces a multitude of calibers in complete rifles and upper receivers. They are well known in smaller circles of the 6.5 Grendel Cult to have well built, accurate rifles that won’t kill your bank account.

Atheris Rifle Company 20″ Upper

The upper that Atheris Rifle Company sent to me was barreled with a 20” Atheris barrel with a thread protector. It uses a mil-spec, forged upper receiver with Strike Industries parts for the dust cover, and an Atheris ambidextrous charging handle. The bolt carrier group is a nitrided system with a 9310-steel bolt. Just like all the other uppers, it performed flawlessly during my tests.


What really drew my eye to this upper is the aesthetics of the free-floated handguard. It is a 15” lightened MLOK handguard that is 100% American made. It is a slim handguard that gives plenty of grip for your hand but still has Picatinny rails on the end of the handguard toward the muzzle for attaching any accessory that you may want for the AR15. By design, the handguard also uses an anti-rotation system for a rock-solid mount.

Artheris Upper – 0.62 MOA at 100-yards

The Atheris 6.5 Grendel upper stepped up the competition at this point. Its best 100 yard 5-shot group measured in at .62 MOA. Once the barrel fouled from previous zeroing shots and at 100 yards, it began to tighten up at 400 yards. This upper’s best 5 shot group at 400 yards measured .5 MOA at 2.09”. Atheris Rifle Company’s experience really shines through with their 6.5 Grendel. At $549, this upper is a shooter and seems to be capable of sub .5 MOA!

Artheris Upper – 0.5 MOA at 400-yards

3. Grendel Hunter 20” Upper

Grendel Hunter is another great company that is well known within the Grendel community. If you are a fan of the 6.5 Grendel, you probably know or have spoken with Andy Hobein, the owner of Grendel Hunter, on forums or on Facebook pages. He has a wealth of knowledge about the Grendel and is always willing to share.

Grendel Hunter 20″ Upper

The Grendel Hunter upper that was sent to me uses a 20” Satern Liberty barrel with a Grendel Hunter designed slanted 3-port muzzle device. The free-floated handguard is also designed by Grendel Hunter and has a slanted angle cut that matches the muzzle device perfectly. The muzzle device is highly efficient in my experience.

Grendel Hunter 20″ Upper

The receiver is an Aero Precision M4E1 upper and is built up with Strike Industries parts, including their dust cover, forward assist, and a Strike Industries charging handle. On the Grendel Hunter website, upgrading is easy with their drop-down menu, allowing customers to customize what they want.

Grendel Hunter Upper – 0.43 MOA at 100-yards

The Grendel Hunter upper was an absolute tack driver during testing. With the Satern Liberty barrel, its best 5-shot group at 100 yards printed a .43 MOA, with one round that opened the group. Once I stretched its legs out to 400 yards, I was able to shoot a .44 MOA, 1.85” group. A sub .5 MOA complete upper at nearly $650, in my opinion, is well worth it. Grendel Hunter has a winner on their hands.

Grendel Hunter Upper – 0.44 MOA at 400-yards

4. Palmetto State Armory 6.5 Grendel 18” Upper

Palmetto State Armory’s offering that was sent to me uses a mil-spec, forged upper receiver.

The bolt carrier group is nitrided and uses a 9310-steel bolt with “6.5 Grendel” laser engraved on the carrier. The upper uses mil-spec parts for the forward assist, charging handle, and dust cover. The handguard is a free-floated, 15” MLOK and is a solid design with an integrated QD attachment point.

Palmetto State Armory 18″ Upper

The 18” 416R stainless steel barrel is manufactured by PSA through D.C. Machine and in my experience, they are typically great shooters for the price. The muzzle device is a typical A2 style muzzle device threaded for a 5/8×24 TPI barrel.  I personally was able to stretch out to 1,000 yards with a PSA 6.5 Grendel rifle while in WY with PSA on a media trip.

PSA Upper – 1.16 MOA at 100-yards

While shooting the PSA Grendel, I was able to shoot a respectable group at 100 yards measuring in at 1.16 MOA. After the initial zeroing and fouling shots, at 400 yards the barrel did prove to be sub-MOA putting out a 5-shot group at .86 MOA measuring in at 3.58”. At its price point, usually being sold at under $400, it is a solid choice for anyone looking for a hunting or recreational long-range shooter.

PSA Upper – 0.86 MOA at 400-yards

5. Sanders Armory 20” Upper

Sanders Armory offers multiple offerings in varying calibers. Kelly Sanders, the owner, can be found on multiple pages dedicated to ARs on Facebook and is always willing to help people with information. While this is getting more normal with social media, in my opinion, when an owner of a company is active on social media, that speaks volumes of their customer service.

Sanders Armory 20″ Upper

The upper that was sent to me has a 20” Sanders Armory barrel in 416R stainless steel with a 3-port stainless muzzle device. The upper is a mil-spec, forged receiver using a nitrided BCG. The handguard is a free-floated 16.5”, clamp-on, key-mod design. It felt very solid running off the shooting bags or when I had mounted a bipod on it.

Sanders Armory 20″ Upper

At 100 yards, this upper was able to print a .57 MOA group. After the other uppers tightening up a bit from all the zeroing shots, and 100-yard groupings, I had high hopes that this upper would do the same. It did not disappoint. Out of all the uppers, the Sanders Armory 20” upper’s best 5 shot group at 400 yards measured .37 MOA and 1.56”.

Sanders Armory Upper – 0.57 MOA at 100-yards

This complete upper is priced at $488 currently, so I feel the need to reiterate IT GROUPED 1.56” AT 400 YARDS! While this upper does not look as flashy as other models, and I personally like MLOK over Key-Mod, this upper is a workhorse that can put up solid results in the accuracy department.

Sanders Armory Upper – 0.37 MOA at 400-yards

The Run Down

In my opinion, all 5 of these uppers are great buys depending on what you want. With that being said, all barrels are different, and YMMV.

Depending on your budget, and what you expect from a rifle, either of these 5 choices could be a viable option. I can’t honestly pick “the best” choice without the expectations of the shooter and their budget.

All 5 Grendel Uppers Sent to the Author

But in the end, hopefully, with the information in this article, you can make your best choice with the money you have.

It is safe to say though, that if you want a long-range cartridge for your AR15, the 6.5 Grendel is a fabulous choice and will get the job done for your paper punching or hunting needs!

    I just put together a PSA complete lower with shipping & FFL ($259), with a Moriarti Armaments upper 6.5 Grendel 18" Heavy nitrite barrel-Mid Length ($316), Rubber City Armory carrier nitrite ($92), Grendel Hunter 6.5 grendel type 2 nitrite bolt ($64), Enhanced firing pin kit with cam pin & cotter pin ($26), 1-5rd mag, 2-10rd mag, 1-20rd mag ($78). Total was $835 for the complete rifle. Have not fired yet, because bullets are hard to get now, but I just ordered 200 rds Hornady Custom 123 gr SST ammo, can't wait to see what she will do.

    Planning a 6.5 grendel build. On the 18" uppers, were they mid-length or rifle length gas? Thanks

    August 28, 2020 7:39 pm
  • Josh P

    Are you certain that Grendelhunter isn't a 19" barrel? I know they offer one and it looks to be between the 18" and 20" in the "all 5" picture?

    July 28, 2020 2:57 pm
    • Ken Whitmore

      I believe Andy Hobein at Grendel Hunter only has a non-threaded muzzle option that is 19". I could be wrong about that though. All barrels were either 18" or 20" that were supplied for this test.

      July 28, 2020 5:39 pm
  • SBraun

    Ken, Any thoughts on Bear Creek Arsenal 6.5 uppers? Their advertised (and pictured) groups look like they would challenge PSA at the same price point.

    May 4, 2020 5:18 pm
    • David, PPT Editor

      Some of their groupings are... very interesting. I would be highly suspect of seeing those groups outside of a highly controlled 3-round test. Their quality control is very patchy from what we've seen, if you're looking for a budget upper I would highly recommend PSA!

      May 4, 2020 5:30 pm
      • SBraun

        Thanks for the quick reply David. Despite the perhaps questionable self reported groups, have you tested any of the BCA uppers in 6.5 or other calibers?

        May 5, 2020 7:47 am

          For what it is worth in the AR-10 vein I just started shooting one of their 243win uppers, could not pass it up for fun, complete for under $300. First two boxes of cheapest Remington 100gr settled shooting 3/4 - 7/8 moa at 200yds. If stays same or gets even better breaking in I will be happy camper. Warning their info says fits dpms but actually fits Black Rain / Windham. I have both so wasnt a big deal for me.

          June 3, 2020 10:34 pm
        • Ken Whitmore

          I have owned a 6.5 Grendel barrel from BCA. Using 123 grain Hornady AMAX, and then the updated Black ELD, I typically shot under 1 MOA 5 shot groups. BUT.... when shooting Hornady SSTs, groups would open to 4" at 100 yards. I got rid of it because it wasnt consistent enough. As far as their uppers go, I would not recommend them due to issues with quality control and proper assembly.

    I have a couple grendel from a 10.5 upper for pistol hunting to the kids side charging 16 inch bca to a ar stoner 20 inch coyote destroyer. What i find is 99% of all grendels ive built and shoot from 500 dollar builds to a grand will just flat out shoot a moa or less if you reload for it. My ar stoner will do .5. To .6 or better all day long the bca thats cheap shoots 5/8 to a inch with 120gr to 100gr. The kids have killed lots of deer most just drt on the spot. For your average shooter you will never push a grendel as far as you can shoot with it my 400 yard range in the yard is longer then most people will ever shoot. Spend money on the glass and learn to shoot then build you a nice upper to hit the 1000 yards with it. The grendel is a great choice but you hand load will take it perform.

    Thank you for the great review. I have been looking to purchase a 6.5 Grendel upper and I have now made my choice for the Sanders. I did talk to the owner on the phone and he was exceptionally friendly and informative. I am looking for precision over everything else so the Sanders wins. Thanks again.

  • Clay Padginton

    I have a Windham Weaponry multi-caliber system AR, they do not make a 6.5 Grendel barrel for it and was wondering if I can just buy a complete upper instead of buying barrel/gas tube and gas block. Which upper will work and was hoping for 20-24" barrel for hunting

  • michael baca

    OOps, left out a detail. I also run a JP polished buffer spring and a KVP 4.3 oz heavy buffer.

    August 1, 2019 2:38 am
  • michael baca

    I guess I should have been more detailed about my finished rifle. I have a Geissele SSA-E and a Vortex Viper PST II 5-25 FFP on an American Defense Recon QD mount . I swapped out the BCG for either a Fail Zero NiBo or a ToolCraft NiBo; can't remember which. I also swapped out the CH for a CBC Industries ambi CH. I run a Vltor EMOD buttstock and an ErgoGrip tactical deluxe grip. OMG this grip is fat and oh so comfy! I think it helps immensely when precision shooting. That about rounds out my build. I have a shitty Amazon bipod that I want to replace with a nice Accushot Atlas.

    I have a Radical Firearms 24" medium contour SS 1:9 upper and shoot nothing but Hornady Black ELD 123g. As they say, it's more accurate than I am. My best 3 shot group so far has been .45" at 100 yds and it shoots well under MOA at 200 yds. My range goes to 600 yds, but they are steel targets so I have no way of seeing what kind of accuracy it has beyond 200 yds since paper targets are not allowed past that distance. When I bought the upper last year it was right about $500 and I got it at JoeBob on sale for about $480. Now they are anywhere from $500-$620. It came with a pepper pot brake that almost seems like it's part of the barrel, as it is very slim and low profile. It mitigates any muzzle flip nicely. The BCG is a standard nitride type and the CH is milspec. The rail is M-lok and very nice, with small sections of pic rail at the 3 o'clock, 6 o'clock and 9 o'clock positions at the muzzle end. Every time I take it out it just feels right and I always look forward to improving my accuracy with it.

    I ordered a 6.5 Grendel, 18” upper from Atheris, because they said they had a sub-Moa guarantee. I ordered the upper and the stainless match barrel and waited for it to be cerakoted. After a month or so it finally came. It looked good, i had put in 2 calls 2 different times to inquire about the shipping status. One call was its gonna ship soon. One call was its gonna ship this week. Then the next call went to vm, i left my info and within an hour they didnt call me back, but sent me a notice that they printed a shipping label. Wouldnt answer or return any of my calls. Then they send me a invitation to write a review. Which i did, i stated the quality and workmanship looked good, but their customer service was lacking and because of that I wouldn’t purchase from them again. It said it had to be approved, i marked it 4 stars. I went to the website to check the review its now 5 stars, and says workmanship seems good, quality looks very good. Thats it. Only 2 lines from my paragraph. A little shady and shitty customer service. I would look at a different company.

    Atheris (Like the spiked bush Viper) Not Artheris. Excellent uppers btw. By far the best bang for the buck.

    I see a lot of suggestions as to better but nobody listed their 100 yd group size. I dont expect everyone to have a 400 yd range but at least post a sample of your 100 yd group. I have a Sanders 18" fluted match upper and I have .65 " to .75" 100 yd groups and I am 67 years old and a cancer survivor with hands that go numb at times through out the day. Others at my club have gotten better results than I did. For the money (half of a 18 " AA upper) I would find it hard to believe that a AA can shoot .35" 100 yd groups with the same ammo. If it can then you got what you paid for but I dont have $1000+ to spend on a hog hunter and part time target rifle.
    It has yet to fail and after using some accuracy oil recommended by Rex Tibor my groups are coming down in size. Maybe the title is wrong and should be the best for under $750. But I can see spending $500 more for a AA upper when mine does all I need and then some.

    5 best? Well your credibility just went to shit. All of those listed are complete trash lol ACME Machine? They source half their crap from China and act like it a great value. Just because 5 awful companies sent you free uppers, doesn’t mean they are the best. Kids, save your money and buy a nice 6.5 barrel. Not this crap. Because yours won’t be free, and they aren’t worth their weight in the Chinesium they are “forged” from.

      I'm with jp64. The groups speak for themselves. Just because you have unending $, doesn't mean the rest of us do. My old 788 is one of the best shooting .223's I've seen. Now that is a "CHEEP" gun.

      March 30, 2019 3:29 pm
      • Trollygag

        They cherry picked the best groups out of who knows how many by their own admission. That's not nearly the same thing as proving the upper. What's the average of everything it shot? I've had uppers that would barely hold 2 MOA but would occasionally shoot 0.5 MOA groups.

    18” Alexander lite barrel/bolt on a Smith and Wesson M&P donor rifle. 15” MI Mlok rail. Ebay muzzle brake lol ( it works really well). Geissele SSA-E trigger. Magpul PRs gen 2 and heavy buffer. Warne 20 MOA cantilever base with Leupold VX5HD 3-15x44 CDS ZL. My hunting load which has dropped every critter in their tracks with perfect heart shots including a 200+ pound whitetail at 321 yards (dialed 6.25 MOA) is 26.9 grains of H4895 in starline brass, CCI 450, 129 Accubond long range (1300 fps minimum velocity), 2.260” OAL. It’s not a barrel burner but it’s always 1/2 MOA at 2285 fps. Start low and work up. Who needs CM velocity when you can expand a bullet at 1300 fps. I’ve taken that load out to 820 yards on steel and it still impacts hard. I’ve tried the Grendel II chamber but my love is with the Saami spec chambers from the ones that started it all.

    16" Ballistic Advantage Premium Fluted assembled on a M4E1 'Enhanced' upper w/12" 'Enhanced' rail. Suppressed running a Sentry7 Adjustable Block. Peccary hunting. Great setup with a 1-8 Strike Eagle. Also a 12.5" BA Hanson build. Grendel still has excellent ballistics at that short of BBL length. A bit over-gassed since I'm using the pinned block rather than an adjustable (when suppressed). Going to take it next season to the reservation for Peccary hunting.

    As for the PSA, I have found they have a good product, but over torque the barrel. Take it apart and resemble at proper spec and you will be amazed. Should get equal or better performance than the Grendel Hunter.

    How's your experience with Bear Creek Arsenal 20" SS non fluted Uppers in 6.5 Grendel?

    January 23, 2019 3:30 pm
    • Ben

      I can speak from personal experience with a Bear Creek 16" M4 profile 6.5 Grendel barrel I built an upper with. 3-4 MOA at 100 yards with starting loads in hornady brass with 123-gr Nosler BTHP's. Had to work to find a load that brought those groups to just over 1 MOA. Lot of hassle. Don't buy Bear Creek. (Slightly) more expensive brands like Ballistic Advantage and Satern offer better barrels that shoot around MOA, usually better, right of the bat.

      I have the 18", which I've read is the optimum length barrel, and it's spot on! I've got no complaints with BCA,and have 7.62x39, and .223 Wylde uppers.

      Spend a few buck more and save time(and money, spent over $100 on ammo to try get BCA to work), I had to return 3 BCA 6.5 Grendel uppers, short chamber problems. My experience BCA upper is 2-3MOA with Hornady factory ammo. The problem only seems to be the Grendel barrels, other chamber types seem to be good, 300bo, .223 Wylde, NATO and 7.62x39.

      what is your rifle twist rate and weight of bullets. In Calif. we can not use lead and have to have longer bullets to get and weight to them.

      January 26, 2019 3:34 pm
      • Reid

        I believe Odin runs 1/8 twist. I was shooting 130gr Sierra Tipped Gamekings, PowerPro Varmint powder at around 2400fps. Not much help on the "no lead" rule. You could move to America where we are free to shoot the lead back into the ground. I wonder if anyone voting this lunacy in questions where we found the lead to start with?

      Exactly, I’ve tried a Saturn barrel and I’ve tried a Ballistic Advantage barrel they didn’t impress me like the 18” Alexander barrel I’m currently running. It’s Saami from now on with any Grendel builds I do.

      Because Alexnder probably wouldn't send a free upper.

    Best uppers I've seen come out of Fort Worth, TX with sgtofarms it's an aero frame jp internals and t-box barrel pulling one hole groups at 100.

    Great write-up. I'm getting into Grendel myself but I'm building a 12" pistol first with a longer range setup later. Will refer back to this post in the future.
