Believe it or not, I’m a bit slow on gun trends.
For the most part, I have what I need when it comes to firearms. People will be running around with this barrel, that new caliber, or some other geejaw for years.
Occasionally though, a trusted name will pop up with something I’ve been interested in checking out, and I’ll bite.
So it was with AR pistols. I know, people have been using them for a long time now!
When I saw Ruger recently entered the foray with a pistol version of their AR-556 platform, I decided to find out what this AR pistol business was all about.
The Ruger AR-556 series has been around a while and they have built a reputation as a solid, entry-level AR-15 that is affordable. You can find them out there for $500 or less, on the regular.
While they may not have a lot of bells and whistles, they are solid and you can set them up however you like. When the pistol version recently came out, I thought it would be an economical way to explore the concept of an AR pistol.

What Is It?
The Ruger AR-556 Pistol has a 10.5-inch barrel that is cold hammer-forged of 4140 chrome-moly.
The 9-inch, free-floated, handguard offers MLOK on the sides and bottom, with a traditional Picatinny rail running down the top.
The gas system is direct impingement and takes advantage of the entire length of the handguard as a “carbine-length”.
The upper enjoys traditional features like a brass deflector and a forward assist, as well as a dust cover. The configuration is slick top and has no BUIS.
It does come with a 30-round Magpul PMAG and also has an SB Tactical, SBA3 Brace on the end that can be adjusted to various positions for different lengths of pull.
All the controls are normal AR-15 standard (not ambidextrous), though the grip appears to be unique to Ruger.
The trigger feels mil-spec and is all business, coming in at 7 pounds, 2.3 ounces on my Lyman Digital Scale.
However, it is solid and only pulls back about 1.5mm before breaking. Reset is tactile and audible. There is also a slightly bowed trigger guard to accommodate a gloved trigger-finger.
Let’s Go Shooting!
I took the Ruger AR-556 Pistol out to the range for the first time after I had mounted a Vortex Diamondback Tactical 4-12×40 scope on a cantilevered mount.

It looked completely ridiculous with the scope being nearly as long as the weapon, but I wanted to test the accuracy of the platform.
I set up at 50 yards and loaded up some magazines with the Aguila Party Pack I was using for the test. This box of ammo consists of 300 rounds of 55-grain 5.56 that won’t break the bank.
Using a Foam Action Sports rest, I shot 5-round groups at 50-yards. Granted, I know the pistol is chambered in 5.56 but I felt 50 yards was a good gauge to check accuracy.
While the results varied, they were all really tight with the best group coming in at around a half-inch.
During testing, I experienced one malfunction but it was a good one. A round jammed into the feed ramp hard enough that I had to mortar the pistol to get it to disengage—nothing else would clear it.
The side of the neck of the casing was a bit marred but once ejected, I continued shooting with no other issues. I learned the 556 Pistol was accurate.
Transform
At last I began to see the potential of the small (but otherwise erstwhile) AR-15. Here was an accurate package that was small enough to conceal in a truck, but could deliver accurate fire and other than one mishap, was reliable to boot.
I began to imagine the possibilities and thought how I might dress the pistol out.
I got a folding stock adapter from Law Tactical because I really wanted to double down on the concealability of this small but potent package.
When it arrived, I spent a short while reviewing videos before installing the unit on the Ruger.

It went smoothly and operated just as advertised, folding the pistol down to a compact 21 inches. Next, I installed a Vortex SPARC AR. This is one of my favorite red dot sights for the AR for a few reasons.
It’s no-frills, simplistic, has a keeper for the lens covers, and does exactly what I need it to do.

With the installs done, I had to head back out to the range to try out the pistol again. The Law Tactical Folder uses a small plug at the end of the BCG to serve as a connector to the buffer spring when the stock is closed.
Since this changed (to a minor degree) the function of the pistol, I had to check reliability.
“Have more than you show, speak less than you know”
Shakespeare’s words could well be the theme for this review. The Ruger AR-556 Pistol, combined with the Vortex red dot, and the Law Tactical Folder stowed up nicely in a backpack, but with a few swift movements, was all the AR-15 goodness I might need in a pinch.
I felt comfortable engaging out to 100 yards but anything 50 and in was easy money. I took the pistol back out to the range a number of times, deploying it and running it through its paces.
I had one more failure with the Aguila 5.56 that needed to be mortared out. I had a hard time diagnosing this and ran the ammo through an AR with zero errors. I also ran Winchester, Tul Ammo, and Hornady through the Ruger and had no more problems.

All in I passed about 500 rounds through the gun and found it performed wonderfully. Shouldering the brace does not work as well as a traditional buttstock, it slides around a little.
But it can be done to deliver accurate fire. The brace is also great if you want to strap it to your wrist as intended by the manufacturer.
By The Numbers
Reliability 4/5
While I struggled to understand what had occurred with the Aguila ammo in the Ruger, the jams only happened twice out of 300 rounds. The gun ran fine on everything else I fed it. Notably, the Aguila used in an AR rifle did not produce the same jam.
Ergonomics 4/5
I am very comfortable with the AR platform and Ruger’s version does not disappoint. The grip is fine and so is the handguard. It is small enough to add accessories, such as a light, and still be easy to grip.
Accuracy 4/5
I was a bit surprised at this, but the pistol’s accuracy was much better than I had anticipated with a 10.5-inch barrel. You do tend to suffer with extra loudness with a barrel that short, but the accuracy obviously did not suffer.
I like to think of firearms as having a median, optimal range and this one excels from zero to 50 yards, with 100 not being out of reach.
Customization 5/5
Ruger did not miss any styling cues in this inexpensive offering. You can add just about anything you want with the MLOK and Picatinny rail. On top of that, I wound consider a trigger replacement, though the one it comes with is more than serviceable.
Additionally, I would replace the charging handle with one more suited to a one-sided pull (simply a training preference).
Finally, one item I would like to add is a horizontal (not vertical dear readers!) grip to give me some assurance that I’m not getting my support hand too close to the muzzle. I have long arms and tend to stretch out, testing that real estate.
Value 4/5
Given the street price we’re seeing for the Ruger AR-556 Pistol, I feel the Ruger is an outstanding value for the price.
It is accurate, reliable, compact, and can be readily customized into whatever configuration you want. Backpack gun? Truck/trunk gun? You got it.
An AR-15 pistol that is this inexpensive while maintaining good quality has been the long-term key to Sturm Ruger’s success.
Overall 4/5
Parting Shots
So. What’s this AR pistol stuff all about? I’ll tell you my friend. For me, it was a journey that led to a discovery.
With the AR pistol, I can take all the proven capability of the AR-15 platform and shrink it down to a lightweight, compact, concealable package I can take with me just about anywhere.

While it certainly isn’t something I’m going to wear in the waistband, it is some extra firepower I can discretely stow or tote for those “just in case” scenarios.
Ruger’s AR pistol is an outstanding value, and a great way to explore this platform for yourself!

I don't mean to rile anyone up, but how is this a pistol? I feel that a pistol is not a weapon that can or should be used with one hand near the barrel; that all pistols should have the hands towards the rear of the weapon. This would be a rifle, being that it's best to fire it with the barrel supported.
Legally, it is a pistol.
We all feel that way about what should be considered a pistol. However, because ATF insists on defining what is and isn't legal for citizens to own, despite the 2nd Amendment, it is ATF/NFA rulings of pistol and short barreled rifles that is causing guns such as this to be defined as "pistols." If you don't like the ATF designations, don't worry, they will probably change their definitions soon... as soon as a director wants to make more weapons illegal for us to own.
Would it be best to run a H2 buffer weight with this firearm?
I built my own AR-15 pistol. I think the folding brace is a great idea. That’s gonna be my next upgrade to ol’ Betsy.
Is it legal to install a folding stock on the AR-556?
It depends on the exact configuration, length, etc. In Sean's case, since he was putting it on what is already legally a pistol - it's legal for him in his state. Your state and your rifle might vary though, so double-check legality and length requirements before adding one.
Pistols are cool, but the only thing i like anymore about ars is building them. I hate shorter barrels, sound/blast n reliable. But still we all love the ar platform...i have a ruger ar556, first model they made. Its absolutely awesome its still my favorite. But not the coolest i have but my fav. Extremely accurate. I have pics 100yards 1-2 moa all day. Ill never get rid of it Beto*. Another comment said about psa. I love psa but ar556s barrel is far superior against every psa barrel i have.
I'm a fan of the PSA AR pistols. I have a 7.5 and a 10.5 and both run great and accurate. I don't think I paid more than $450 for each. Unfortunately, I lost them in a boating accident.
Good man. What Beto doesn't know won't hurt him.
For us newbie's, can you be a little more descriptive than "needed to be mortared out"?
Great question...it's when a round gets stuck in the chamber of an AR-15 and cannot be removed with the charging handle. You tilt the gun towards the sky, and pull the charging handle while slamming the buttstock on the ground.
Mark,
Eric is absolutely correct. The only thing I would add is I try slamming the buttstock on my chest/shoulder first while pulling back on the charging handle. If you can free the stuck round this way, it is normally safer because it's easier to point the gun downrange, and in a safe direction.
Sometimes its not enough though and you need to collapse the buttstock (if adjustable) and then bang the rifle down (buttstock first) while simultaneously pulling on the charging handle.
Sean
As long as the brace does not touch your shoulder, your good ! Having the pistol brace
against your cheek provides for a decent hold and adds to accuracy. Many of the
photos I see appears as if the brace is against the shoulder but, if you look a little closer
you can see there is space and the firearms is not touching the shoulder.
To my understanding......as long as the brace is not against your shoulder.....your good !
Incorrect. As long as you do not modify or change the brace (remove Velcro strap, etc.) you CAN shoulder the weapon. Do your research people. Google is your friend.
i've never heard this one. Hope it's true......I LIKE IT !!!
yes, the ATF has changed the rules on shouldering the brace. granted you're not supposed to ALWAYS shoulder it, but if you do it from time to time then it's totally fine.
still no vertical foregrips though.
You are correct. The ATF changed their original ruling.
Wait - the Ruling that they just changed a month ago or are you speaking of the ruling a month or two ago?
