Magpul STR Commercial Stock for AR-15
Featuring a compact polymer reinforced A-frame design with improved cheek weld and two water-resistant battery tubes, the Magpul STR Carbine Stock replacement butt-stock for the AR15/M16 has created quite the stir. This is especially true considering the use of commercial-spec sized extension receiver tubes that is part of the overall design.
To prevent operating the weapon by accident, the operating lever is shielded and there is a supplemental friction locking system as well. Plus, the overall design helps to minimize moving the stock around too much which creates greater stability as well as accuracy.
You’ll find a reversible, push button QD sling mount, two integral sling loops and a .3” rubber butt-pad which is replaceable and helps prevent slippage even if you are wearing body armor or other types of gear. Made in the USA, the Magpul STR Carbine AR 15 stock is certainly a well crafted device for your firearm.

Customer Ratings & Reviews
Great AR Stock
This is a great AR15 stock. Big improvement over the standard AR stock. I have two of them, one on a Ruger AR556 and one on a Smith & Wesson M&P15. In each case, they fit perfectly so there's no rattle and they adjust with just a little bit of tug, but they still slide easily and smoothly. The offer superior cheek weld over standard stocks as well.
The BEST AR stock out there!!!
A friend bought a new Armalite Tactical M15 that came with this Magpul Stock ...... what a difference over the average ar 15 adjustable stock!! The cheek rest really makes getting to the same hold MUCH easier and sets up perfectly with open sights or optics. I mounted mine on my Ruger lower and use it on my 3 Gun upper as well as my Military match upper. The ability to "lock" it makes all movement go away.
I would buy this Magpul AR Stock again.
I purchased this AR stock as I had seen it on a friends AR build and like it's appearance, but mostly I like the added width which aids in a comfortable cheek weld. The Magpul stock is very sturdy, and I will buy another for my next build. All in all a very well made stock.
Great AR15 stock!!!
I used this Magpul stock on my last build (high end San Tan tactical precision rifle) this is my favorite Magpul AR15 stock in the magpul lineup. The beveled cheek weld is perfect, and doubles as battery storage. The other feature I really like is the secondary lock, that really holds the stock solid, with no slop or wiggle. I know there are hundreds of choices, but this stock feels the best to me.
Strongly recommend this Magpul stock!!!!!!
Bought the commercial version for my bushmaster AR15. Had extremely tight lock up, excellent cheek weld. For me the stock puts my face in the correct position for my optic easily and quickly. I would recommend this AR15 stock to anyone, I believe it's the best bang for the buck out of the MagPul stock options.
I am using it for my Airsoft Rifle. Great and comfortable, can't beat the replicas for a tad more. I love this thing to death! The only downside is the plastic bullet it comes with to help you install isn't the best. Take a small flat head and depress the pin down while holding the lever down to slide it onto your buffer tube.
Looks great on my Armalite AR-10 and wasn't hard to install. Slipped it on over a DPMS 6 position commercial extension tube.
Magpul STR carbine stock is Excellent
The Magpul str Excellent stock. I've tried many different stocks over the years, and this one is definitely at the top of my list. Great features, locks uptight. Not to mention, it's great looking, too.
Magpul STR commercial stock is Great
I bought this Magpul str commercial stock about three months ago to replace CTR stock because I wanted a better cheek weld. It went on fairly easily and sat snug on my commercial buffer tube. The locking mechanism is great and secures the stock to the rifle as if it were a fixed stock. It is the most comfortable stock I have ever put on any of my AR builds! In my opinion, of course. Now one issue people commonly report is there are no springs, so the batteries wiggle around. An EASY solution to that is to put a foam earplug in the battery tube before you insert the batteries. This gives them a secure seat, and they do not wiggle nearly as much anymore. That's a what, $1 investment at most for the earplugs?? Overall great stock, and high quality as you would expect from any Magpul stock.
my favorite Magpul stock
The STR is my favorite of all the Magpul stocks. I Use it on My 300blk that I hunt with. Has excellent cheek weld and locks up solid. No rattle. I really like this AR stock.
