Guide to assorted AR15 carbine stocks

LMT SOPMOD

The LMT SOPMOD stock is currently issued to members of SOCOM who are being issued equipment out of that inventory. The LMT SOPMOD looks unlike most other stocks, and was one of the first carbine stocks created that really seemed to break the mold. This stock has battery storage compartments, and also comes with a built in rubber pad. The rubber pad reduces slippage on nylon tac gear, and is a nice improvement overall.

Magpul CTR Stock/ Compact Type Restricted

Military and Commercial


Magpul created a carbine stock that was unlike anything else currently on the market. It incorporates a lock, which cams the stock against the receiver extension (buffer tube). This means your stock isn't going to wobble or feel loose. While that may not make a difference to some people, it makes a huge difference to others. Regardless of which way you feel, I don't know of anyone who is going to complain about a stock that feels "extra" solid.

The Magpul CTR comes standard with a female QD mount in place. This allows for any sling which can use standard QD mounts. These are most often found on 2 point slings, most notable is the Vickers Combat Application Sling, which is also available through Magpul.


The commercial variant of the CTR is easily identifiable due to its thicker rubber pad on the stock. This is done to enshroud the angular buffer tube which comes on some commercial receiver extensions (buffer tubes).

The standard Mil Spec CTR does not come with the rubber pad, though its something which reduces the stock sliding around on your shoulder and increases overall functionality in my book.

Vltor Carbine Modstock


The Vltor stock is available for Mil Spec receiver extensions (buffer tubes). Vltor stocks are easy to recognize with their battery storage compartments, which can be installed or removed on either side. More than just carrying batteries or other items, these compartments offer an outstanding cheekweld which often needs to be felt to be appreciated.

Vltor stocks come with a built in QD mounting point, but also include a top retaining piece, which makes it simple for the end user to go with whatever style sling they want.

Colt Ribbed Stock- Similar to CMT/ Stag ribbed stocks.

The below stock is standard issue on the military M4.











Below is a picture of an aftermarket stock. The stock on top is Colt, while the bottom is RRA. CMT/ Stag uses a milspec size, while RRA, DPMS, Bushmaser, Olympic Arms, and a few others use a commercial size instead. From the picture you can see that they are similar, but not quite the same in overall appearance. Non-Colt stocks, tend to all have a rounded section instead of the squared off portion.

Colt CAR Style Stock- Similar to CMT/ Stag stock


This basic style has been around since Colt first introduced their carbine. It started out made of aluminum, and later was changed to a plastic. Both styles are still available, with polymer variants being much more popular. This style of stock comes in both commercial and military spec sizes.
