Mountain Billy Gun Lab Goat-15 Atom .22 LR Pistol, 7.8-inch

The Mountain Billy Gun Lab Goat-15 Atom is a .22 LR AR-platform pistol (brand part no. MBGL-GOAT15-ATOM-1-HC) built around a 7.8-inch black oxide threaded barrel. Mountain Billy Gun Lab builds the Goat-15 line on a black polymer receiver rather than aluminum, keeping the pistol lightweight for its size while still running a full Picatinny top rail and an M-LOK handguard for optics and accessories. Chambered in inexpensive .22 LR, this compact AR-pattern pistol suits plinking, training, and pest control at a fraction of the ammunition cost of a centerfire AR pistol.
