[Review] Radical Firearms Upper

If you’re always hunting deals (make sure you like and follow us on Facebook, we post 3-4 every day) you probably have seen something from Radical Firearms for sale on the cheap.

I’m talking, complete rifles selling for $500-$600, uppers for $200…that kind of cheap.

Of course, when you’re looking at something that uses an explosion to fire a 55gr projectile out at 3,200 feet per second, is it really the best idea to go cheap?

That’s what I wanted to find out.  

I found a Radical Firearms upper for sale for the rock-bottom, the you-gotta-be-kidding-me price of $190.  This was an assembled upper minus BCG and charging handle, for less than $200 even with shipping

BCG and Charging Handle not included.

How did it shake out?  Is a $200 upper worth it?

Let’s find out.

A Little Background on Radical Firearms

Radical Firearms is a relative newcomer to the AR-15 world.  I first heard about them when they brought some of their work to SHOT Show in 2016 or so, but they’ve been around for about five years now.

In that half-decade, they’ve expanded rapidly and carved out a niche for themselves as one of the best budget manufacturers in the business.  

How did they do that?

They decided to start making as many parts as they could in-house.

Be sure to check out the awesome article from Breach Bang Clear about Radical’s business.

This afforded them the opportunity to exercise a high degree of control over their manufacturing, while also allowing them to cut out a lot of the middleman markup that gets slapped on rifles by “manufacturers” that just assemble guns from third-party parts, rather than making everything in-house.

And make no mistake, they are a manufacturer.  They make every part of the rifles they sell, other than barrels, pins/springs, and LPKS.  Their site also says they don’t make BCGs but I think that info is a bit out of date as I’ve seen a number of Radical Firearms branded BCGs out there.

They are also an American manufacturer, which I know is important to a lot of folks, and best of all they prefer to hire vets and LE personnel when they can, like many in the firearms industry.

Why I Bought The Radical Firearms Upper

This all leads me to this review and why I bought a Radical Firearms upper of my very own.

Now, like I said, Radical and PS buried the hatchet over the misunderstanding and everyone moved on.  But it left a wonky taste in my mouth. I know the smell of PR spin when it passes my nostrils, and this felt a little…off.

So I decided to see for myself, and I didn’t want to contact Radical about getting a T&E upper in to check out.   I wanted a regular ole upper off the warehouse shelf, just like the one you would get if you ordered one.  

Radical upper
I was worried about the handguard screws, but so far I haven’t had any issues.

I searched around and found one at Optics Planet and snapped it up during last year’s Black Friday sale.  

I did this for two reasons.

  1. I wanted to be as unbiased as possible, and avoid getting a T&E/review upper that might get looked over a little more on the way out the door.  Not that I don’t trust the folks at Radical Firearms, I just don’t trust anybody, especially not when they’re offering me cheap prices.
  2. I needed another upper, and I’m at that age now where I have to buy Christmas presents for every-freaking-body in the world, so money is tight around our house from about Halloween to Valentine’s Day and the Radical Firearms upper was cheap.  Cheap is good.  Me and the missus like cheap. 

So, is Radical Firearms another in a long line of fly-by-night machine shops turning out AR parts with sloppy standards and poor practices?

Or are they something else?  Maybe even a sorely needed quality, American manufacturer offering good rifles at great prices?

I wanted to know, and I sure found out.

The Upper Itself

The upper I bought had a 15” MLOK rail, and A2 flash hider, and not much else going for it.  I like the shape of the handguard, it has a sort of quasi-rounded thing going on with a flattish bottom.

Radical fitment
The finish on the pivot pin hole is a little lacking and seems to be more like a paint than an actual anodized finished, but I suppose corners have to be cut somewhere, and it shouldn’t be an issue.

Machining is totally adequate.  I noticed no rough edges, file marks, burrs, or other machining imperfections.  Everything is totally in spec and I had no problems fitting the upper to a variety of lowers, including two Aero lowers, a Spikes lower, and an Anderson lower.  

Testing the Radical Firearms Upper

Now, the upper I received was sans BCG and charging handle, so I added my own until I could get a Radical Firearms BCG, which I’ll talk about it a minute.

For now, I threw in a spare Aero Precision BCG and a generic charging handle that came from…somewhere.  I throw BCM Gunfighter handles on all my guns, so this one probably came off a complete upper or something.

With that, I inspected the upper, daubed a little Dykem layout/machining fluid on the screws holding the handguard in place so I could see if they were turning or working themselves out under recoil, lubed everything that needed lubing, slapped the upper on an Aero complete lower, and hit the range.

I packed a little over 250 rounds on that first outing, a mix of Federal American Eagle, range-quality handloads, and a box of Federal Gold Medal, all with 77gr bullets to take maximum advantage of the 1:7 twist barrel.

I also slapped a Bushnell TRS red dot, my personal favorite cheapo optic, on top of the upper’s full-length rail. I chose this because I figure most people who buy these aren’t going to be putting something super expensive like the absolutely amazing Aimpoint PRO on top of it.

And again, there’s nothing wrong with a budget rifle, as long as it works.  If you aren’t a precision shooter, the difference between a sub-1” group and a 2.5” group isn’t a big deal, but you will pay through the nose for the former and can throw together a rifle that’ll do the latter for about $600.  

I zeroed this setup in at 25 yards, and then stepped over to the 100, 200, and 400 yard stretches to see what it could really do.

Again, this is with a mix of ammo, and honestly, I didn’t expect much out of the upper.  At $190, if I could hit pie plates at 100 yards, I’d have gone home happy.  I set out to build a beater gun after all.

But holy shit did I underestimate this upper.

I was hitting 6” steel plates at 100 yards with absolutely boring regularity, the staccato pingpingping of rapid-fire impacts setting the plate swinging on the chains.

At fifty yards, I was left with one ragged dime-sized hole.  

Reaching out to 400 yards, I was able to fairly easily smack a steel pig silhouette target, though I was pushing myself more than the rifle, and I’ll take credit for any misses.

Punching paper with the Gold Medal ammo was equally surprising.  I swapped in a Vortex Strike Eagle 1-6x scope and after a quick bore sight and about a third of a mag to really dial the scope in, I was getting easy 2 MOA groups at 100 and 200 yards, and a best group of 1.8 inches (measured center to center with calipers) at 100 yards.

 

I noticed no keyholing or other weirdness, and I shot the full 250 or so rounds without a single issue (this was with beat up PMAGS and one steel GI mag).

Now, is any of that matching accuracy?  No, of course not.  I have AR’s that’ll punch ¾ MOA groups all day.  

But those rifles have an extra digit on their price tag.  Nowhere do I see Radical Firearms claiming to make the most accurate guns in the world for $600.  I see them saying they make guns that work for $600, and their upper certainly reflects that.

Since November, I’ve put about a thousand rounds through this upper, cleaned it once, lubed it three or four times, and I’ve experienced precisely two malfunctions, both from the same mag.

That mag also had problems feeding in a $2,500 rifle where it actually causes a double feed (and some swearing).

Overall Impressions

Overall, I was very impressed with the Radical Upper I received.

The rumors and the gossip and the snide remarks are all just hot air.  I think Radical Firearms is a good company that makes great products, and they are definitely a manufacturer to keep your eye on.

When I was researching them beforehand, I saw a lot of comments from others about the low quality of their products, and machining issues, and “Chinesium” and on and on and on.  

But I noticed that these were always comments from people who had a “friend” who owned one.  Or somebody was quoting somebody that overheard somebody that…was full of it.

I haven’t seen very many complaints ( none, really) from people who own Radical Firearms products, and I can say, since I purchased this thing with my own money, that I also have no complaints about the upper I bought and tested for this review, and others are saying the same.

Will it knock the wings off a fly at a thousand yards?  Not unless you get very lucky, but not every rifle needs to be that accurate.

For me, for this rifle, I wanted something I could abuse and knock around, and still count on it to hit what I was aiming at inside 400 yards or so.  And this does that.

If you’re looking for a reliable beater gun, an entry-level upper for a new build project, or even something that’s competition-ready on a tight budget, I can’t think of a better value for your dollar than these uppers.

And they’re available in everything from 7.62×39 to the hot new .224 Valkyrie, so you can get one for every occasion.

Parting Shots

I’m happy with my purchase, and anyone who complains about a $200 upper that goes bang every time and puts rounds on target is probably just looking for something to complain about.

I took a roll of the dice and bought a RF 13.5″ 300 blk pistol (4150 heavy profile barrel) and holy crap was I surprised when we took it to the range. One of my (grown) sons took 6 shots at 100 yards after zeroing at 35 and 50 yds. This young man is a novice shooter but the first two shots were 1/4″ apart and the third right at 1″ from the first two. The next three had two shots kissing and the third about 1.5″ away. He got up and said he was done while my jaw was… Read more »

Correction on my long winded post. The RF pistol is 10.5 “ and the barrel is 4150 M4 profile

Bought a 300blk upper a year ago. The first time I shot it, it didn’t cycle. The gas block came without set screws and it slid down the barrel when I fired it. It wasn’t too difficult to fix. Radical firearms offered to exchange the upper but I just bought some set crews and fixed it myself. I’ve put about 300 rounds through it with no other issues. Definitely worth the $200 I spent on the 300blk upper. I just ordered a 5.56 upper on clearance for $142 with shipping and will comment when I get that one as well.

I just bought one. Complete rifle with the 15″ socom barrel and MFT furniture. So far I have about 360 rounds through it. The only problem I had was with the magazine that came with it not wanting to feed when full. I used Amend2 mags that worked great. Put a 1-6X24 Primary Arms scope on it and had it zeroed in 8 rounds at 100m. Just wished I didn’t forget my spotting scope. But anyways so far so good. Everything is tight and seems to be made very well. Hopefully the range is less busy the next time so… Read more »

I purchased a 7.62×39 upper from Radical 2 years ago. I’ve put at least 40,000 rounds through it and never had an issue. The only mod I did was swap the firing pin for an enhanced pin (a little longer) so I can blast crap steel ammo all day. Great upper.

What lower are you running it on? If you don’t mind me asking.
