The Mountain Billy Gun Lab Goat-15 Helium is a USA-made .22 LR semi-automatic rifle engineered for shooters who value lightweight portability without compromising on modern sporting rifle functionality. Built with polymer construction throughout and weighing just 2 lbs 14 oz unloaded, this compact .22 delivers genuine versatility whether you're training at the range, running steel challenge courses, or carrying it on backcountry hunts and outdoor adventures. The blow-back action cycles reliably while the patented tamper-resistant safety gives you confidence in handling and operation.

The Goat-15 Helium's 16-inch CMV steel barrel sports a 1:16 right-hand twist and is threaded 1/2-28 for suppressor or muzzle device compatibility. A 7-position adjustable buttstock lets you dial in length of pull for your frame and gear, while the integrated Picatinny rail with M-Lok slots accepts optics and accessories. The ergonomic polymer lower and upper receiver design keeps the whole gun light and maneuverable—ideal if you're carrying miles into hunting country or need a rifle that doesn't wear you out during extended range sessions.

Ships with both a single-round and 10-round magazine so you can practice deliberate shooting or run through drills faster. The open receiver design means you'll want to add a red dot or other optic (not included) to maximize accuracy potential. Whether you're a competitive shooter honing precision skills, a new shooter looking for a forgiving trainer, or an outdoorsperson seeking a lightweight .22 that handles like a modern rifle, the Goat-15 Helium delivers legitimate capability in a package that won't slow you down.
