Full description and what we offer

Eric and Heidi founded Mountain Billy Gun Lab after 30 years working in the firearms industry. Their combined passion for hunting, shooting sports, and off-the-grid adventures drove them to solve a problem: existing AR-15 platforms were too heavy and too much recoil for serious training, small-frame shooters, and backcountry work.

The result? The GOAT-15 line—ultra-lightweight .22LR rifles that function like modern sporting rifles but weigh barely 3 pounds loaded.

All GOAT-15 models are chambered in .22LR and made in the USA with premium polymer and aluminum construction. They're engineered to be 20% more compact than standard AR-15s while maintaining reliability and accuracy.
