Magpul ACS Carbine Stock, Mil-Spec is rated 4.6 out of 5 by 11.

Rated 5 out of 5 by Mike430 from My favorite stock I've been through numerous different stocks for my various AR rifles but this is by far my favorite of the Magpul line. I have a Vltor Emod which is similar in appearance and storage however the ACS takes the prize to me. It's comfortable and provides a solid, comfortable cheek weld, the two storage tubes are easily accessed from the rear of the stock, unlike those of the Vltor which are accessed from the front (closer to the receiver end plate). On the ACS, the tubes are secured by captive covers while the covers on the Vltor are non-captive and slightly more difficult to access. The side storage compartment on the ACS is on the right side and secures with a latch making it unlikely to come open accidentally while the compartment on the Vltor is held closed by a latch that seems to rely on the sling swivel (which must be removed to access the compartment) to keep it solidly closed. All compartments are roughly the same size on both stocks. The stock latch on the ACS is large, easy to find and easy to manipulate while the on the Vltor is smaller and a little harder to manipulate, especially if wearing gloves. Fit and finish on both are excellent. I've had the Vltor for close to 10 years and while the latch to the side compartment has started to lose it's ability to hold the compartment closed, there are no other issues with it. When you compare the Vltor at an average of $115 to the ACS which I have picked up for around $80, to me the choice is clear. The features are similar with the ACS having the slight edge with it's tethered lids and rear access to the the side tubes and the positive latching of the side side compartment. I'm gradually replacing all of my AR stocks with the ACS as I like the ability to carry batteries and small parts on each rifle. Couple it with a pistol grip with storage capacity and you can carry enough of the parts that you may commonly need to replace in the field and enough batteries to keep your optics, lights and/or lasers running for extended periods.

Rated 5 out of 5 by MobileSniper from Magpul innovation at a great price and superb quality I purchased this to go on my Mil-Spec DDM4V7 in 6.8. The was easy to install and fit like a glove. When I engage the friction lock it makes the stock so solid that there is NO play whatsoever and it rivals how solid a standard A2 fixed buttstock is. The battery storage tubes hold a combined total of 6 CR123A batteries (Plenty to reload your tac-light or weapon mounted tac-light/laser). The storage compartment on the side of the stock is small, but a perfect place for keeping any wrenches needed for making adjustments to mounted accessories, as well as SOME small parts such as spare firing pin retaining pins. I fully trust this product to not let me down when my life is on the line and i'm forced to go to my rifle that rides in the back with my "go gear"

Rated 2 out of 5 by oldpool from Fair price for the product Can't say much at this point, the locking latch broke off when started installation, so I'm awaiting it's replacement. As normal, Sportsmans' Guide's people were very helpful and took care of my return etc. thanks.

Rated 5 out of 5 by tbone01 from Great Stock! This is a great stock, much better cheek weld compared to a standard milspec type stock. The battery storage is a nice bonus (I had to put some paper towel in there to stop the rattling, but no big deal). Installation is a piece of cake.
