Mountain Billy Gun Lab GOAT-15 .22 LR 10-Rd Magazine w/ Load Assist Button

The Mountain Billy Gun Lab GOAT-15 10-Round Magazine is the factory OEM .22 LR magazine designed specifically for Mountain Billy Gun Lab's lightweight GOAT-15 rimfire platform. Built to feed reliably in both the GOAT-15 rifle and ATOM pistol configurations, this 10-round magazine keeps the world's smallest AR-style platform topped off and ready to go.

Constructed from a durable blend of polymer and aluminum, the body drops smoothly into the proprietary GOAT-15 lower and seats securely without play. A factory-equipped load assist button on the side lets you push rounds down into the magazine body with your thumb, taking the strain off your fingers during extended range sessions or training drills.

Because the GOAT-15 uses a proprietary magazine pattern rather than a standard AR-15 mag, this OEM unit is the correct replacement or spare for anyone running the Mountain Billy Gun Lab GOAT-15 line. Whether you shoot the full-size GOAT-15 rifle, the compact ATOM pistol, or another GOAT-15 variant, this 10-round .22 LR magazine delivers consistent rimfire feeding with the load-assist convenience built in.
