Magpul MAG315-BLK AR-Platform Butt Pad - Black Rubber 0.30"

The Magpul MAG315-BLK AR-platform butt pad is a straightforward upgrade for shooters who want better control and comfort at the shoulder. This 0.30" rubber pad comes standard on several Magpul stock models—the CTR, MOE Mil-Spec, STR, ACS-L, ACS, and UBR—and is easy to install on compatible AR stocks as a replacement or upgrade. The firm rubber compound is engineered to give you a more stable grip against your shoulder during shooting and to absorb impact energy if your rifle takes a hard knock or drop.

If you're running a commercial-spec MOE or CTR stock, this pad can be installed, though it's worth noting that the slightly thicker pad may limit your ability to fully collapse the stock to its shortest position. For shooters who don't regularly collapse their stocks, this is rarely an issue. Installation is straightforward—all mounting hardware is included in the box.

Whether you're building an AR from the ground up or refreshing an older stock that's seen better days, this pad is an easy way to improve the feel and function of your carbine without breaking the bank or requiring gunsmithing.

Frequently Asked Questions

What AR stocks is this butt pad compatible with?

The Magpul MAG315-BLK comes standard on CTR, MOE Mil-Spec, STR, ACS-L, ACS, and UBR stocks. It can also be installed on commercial-spec MOE and CTR models, though doing so may prevent full collapse of the stock.

Yes, all mounting hardware needed to install the butt pad is included.

Will this pad fit on a fully collapsed stock?

What's the benefit of the rubber construction?

The firm rubber is designed to improve your shoulder purchase and control during shooting, and it helps absorb and mitigate impact energy if your rifle is dropped or subjected to hard handling.
