The Ultralight .22 Semi-Auto Rifle – Mountain Billy Gun Lab GOAT-15 22LR 16″ Rifle
Tipping the scales at an incredibly light 2 lbs 6 oz unloaded, this unique .22 caliber semi-automatic rifle brings unprecedented portability to small game hunting and plinking. Despite its feathery weight, it doesn’t compromise on performance. Mountain Billy Gun Lab touts it as “the lightest semi-automatic rifle in the world”.
The GOAT-15 is 20% smaller than a typical AR-15, making it a perfect miniature platform for .22LR.

Its compact 27.75″-30.75″ overall size also makes it easy to maneuver and store.
