    Magpul ACS Carbine Stock for AR-15 (Commercial)

    If you wish to have the best when it comes to commercial spec model carbine stocks, then you are in the right place. The typical AR Stock your weapon comes with from the factory might be good enough for a rookie, but any seasoned weapon handler knows that there is a fine balance that makes a weapon great. This fine balance can only be achieved through customization of the weapon and Magpul offers limitless supplies of products to do just that.

    The Magpul ACS is the perfect drop-in replacement for your old carbine stock and can be adjusted easily on any commercial-spec extension receiver tube. Mind that if you own a military spec model, you should go and buy the military spec ACS instead for compatibility reasons.

    This fantastic Magpul Stock has dual battery storing tubes, which can be accessed from the rear and are watertight. From the right, you can access the stock’s storage compartment, which raises the utility quality of this stock even more. The unique friction lock minimizes weapon wobble, increasing durability and stability.

    Chrome-silicon springs prevent auto-collapse, and the particular latch protective design prevents any accidental latch activation or snagging.

    Sling mounts allow for the adjustment of a push-button swivel (up to 1.5”) and a 1.00” sling loop. The ACS comes with the typical Magpul butt pad, made of rubber and specially designed to prevent the weapon from slipping off the operator’s shoulder during use. This is crucial when the operator wear armor or any other smooth equipment on the shoulder. The ACS has four different colors to choose from: dark earth, foliage green, black and olive drab, all entirely compatible with camouflage.

    Features and Benefits of the Magpul ACS Stock:

    • Can be adjusted onto any commercial spec extension receiver tube (it is not included in the order). These are usually made by manufacturers like Olympic, Bushmaster, DPMS, RRA and others.
    • Special friction lock minimizes wobble.
    • Chrome silicon springs prevents auto-collapse.
    • Streamlined design prevents accidental latch activation and snagging.
    • Four colors to choose from: Black, olive drab, foliage green and dark earth.
    • Two watertight tubes to hold batteries, accessible from the rear, and a storage compartment, accessible from the right.
    • Sling mounts. One fro a push-button swivel up to 1.5” and one for a sling loop 1.00”.
    • Rubber butt-pad, which helps avoid weapon slippage.
    • MAG335 already included

    If you want one of the best commercial spec carbine stocks out there, then the Magpul ACS is certainly a choice you must consider. Get yours now or you’ll regret it later!

    Great AR upgrade. The friction lock lever pops down when you pull the lever to adjust the lop. Squeeze it shut, and it locks the stock from rattling or moving. It works great. The side storage is excellent, and the tube storage caps are attached to the stock with rubber strips, so you can't lose them. When shouldered, it is a natural fit for me. Better than the original stock for sure. Comfortable and no more rattles. I didn't get a sticker but instead found a qd cup in the storage compartment! And it also came with a Magpul dummy round. Don't use a dummy round to install stock; the plastic round will break the tip off. Use a punch or a thin phillips screwdriver.

    Great Stock

    I would give this a 5-star, but I always think anything can be improved somehow. I have no complaints about this stock at all. Well, with the exception, I ordered the wrong one at first. I had to return the mil-spec cause I didn't realize my buffer tube was commercial until it was too late. It's got a great design and is very comfortable. Got to love the extra storage for gun multi tool, ear plugs, etc. Also, I have the Magpul MIAD grip, which comes with a storage compartment in the handle with the gun oil bottle. I love MAGPUL products, the company's history with leaving Colorado, and their products are durable, sharp looking, fit the need, and are very reasonable with their prices, unlike some companies. Glad to see Cabelas, "my favorite store ever," supports MAGPUL as I do. You can't go wrong with Cabelas. I tried to find better deals on my stuff, and Cabelas was pretty much the best every time, and their customer service is awesome.

    Excellent ar 15 stock

    I purchased this AR stock as an upgrade; absolutely worth every penny... The comfort compared to my original is not even in the same league... it feels so much better after shooting 100+ rounds down range with this magpul butt stock... The "compartments" are not of much use for me, but they are there if I wanna use them... Serves more as a cheek rest for me actually... If you still have the stock butt stock, I highly recommend this product

    Went on easily and fit perfectly. No wobble and offers a great cheek weld for using a scope or red dot scope. Will probably be buying another one for my son's DPMS soon. Great AR Stock.

    I got the Magpul ACS carbine stock to upgrade loose OEM stock. The Fit and function of the Magpul Stock were excellent. Can't overemphasize to buyers about reading the full description of products. I ordered the Commercial model which fit fine but have seen many bad reviews here and other sites where complaint was about fit.

    I have not purchased a MagPul stock yet that isn't well made. I got the right size, and it is better than the factory original. Like some, the storage will probably go unused, but I wanted the wider cheek-weld. I did have some batteries go out in a recent match, so I may try putting some in the stock.

    Fits tight with no play. I agree easy to install if you don't follow the instructions, a little common sense goes farther than the instructions included. First one I received was damage and they took care of it ASAP. Shipped a new one with no problems!
