Mountain Billy Gun Lab Goat-15 Helium 22 LR 16" 10+1 Semi-Auto Rifle - Hicap

The Mountain Billy Gun Lab GOAT-15 Helium is a USA-made AR-platform 22 LR semi-automatic rifle engineered as one of the lightest rimfire sporting rifles on the market. Built around a polymer receiver and a 16" threaded CMV steel barrel, the Helium tips the scales at just 2.14 lbs while stretching to a compact 27.75" overall length.

Feeding is handled by a 10+1 magazine (the "Hicap" configuration), and the rifle ships with both a 1-round and a 10-round magazine so you can start with low-capacity familiarization and easily move up to standard run time. The action runs on a 1:16" RH twist well-suited for standard and high-velocity 22 LR ammunition, and the threaded muzzle allows easy attachment of a suppressor or muzzle device. A right-hand platform with a safety selector rounds out the user interface, all wrapped in a polymer-receiver chassis that drops weight without sacrificing the familiar AR-style controls.
