Mountain Billy Gun Lab GOAT-15 ATOM 22 LR 7.8" 10+1 Semi-Auto Pistol

The Mountain Billy Gun Lab GOAT-15 ATOM is an ultra-lightweight, AR-style 22 LR pistol built around a black polymer receiver topped with a full-length Picatinny optics rail. Chambered in the easy-shooting .22 Long Rifle cartridge, it functions like a modern sporting rifle in a compact pistol footprint - ideal for plinking, training, and small-game control.

This ATOM feeds from a 10-round detachable magazine for a 10+1 capacity and runs on a semi-automatic action. The 7.8" CMV steel barrel is finished in black oxide and comes threaded at the muzzle, ready for a suppressor or muzzle device of your choice. Up front, the M-LOK handguard offers a slim, ergonomic platform for accessories without adding bulk.

Designed with portability and all-day shooting comfort in mind, the ATOM uses a black polymer grip that keeps the platform balanced and easy to manipulate. A simple thumb safety sits within reach of the shooting hand for confident handling. Proudly Made in the USA.

Includes: 2 detachable magazines.
