Mountain Billy Gun Lab GOAT-15 .22 LR 20-Round Magazine - MBGL-GOAT15-MAG-20RD - UPC 850022225734
Product Description
The Mountain Billy Gun Lab GOAT-15 20-Round Magazine (MBGL-GOAT15-MAG-20RD) is an official factory OEM proprietary feed source engineered exclusively for the scaled-down GOAT-15 .22 LR firearm platform. Purpose-built to support Mountain Billy Gun Lab’s lightweight, compact series of rimfire firearms—including the GOAT-15 Helium rifle, GOAT-15 H2 SBR, and GOAT-15 ATOM pistol—this magazine inserts directly into the proprietary 20% scaled-down receiver magwell for a precise, reliable fit.
Constructed from high-impact, lightweight polymer, the GOAT-15 20-round magazine is designed for exceptional structural durability during dynamic shooting sessions and outdoor recreation. The magazine features an integrated side load-assist button that allows shooters to compress the heavy-duty internal spring effortlessly during loading, minimizing hand fatigue and ensuring consistent round alignment.
Whether introducing new shooters to firearm safety, running steel challenge drills, or carrying a lightweight rimfire kit on backcountry hikes, this factory OEM 20-round magazine delivers smooth feeding geometry, lightweight ergonomics, and authentic Mountain Billy Gun Lab quality.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Proprietary fit exclusively for Mountain Billy Gun Lab GOAT-15 .22 LR rifles, SBRs, and pistols (Helium, H2, ATOM series). Note: This magazine is engineered for scaled-down GOAT-15 magwells and WILL NOT fit standard AR-15 magazine wells or standard AR-22 conversion kits.
- Verify the firearm is completely clear, safe, and unloaded before testing magazine fitment or loading.
- Depress the side load-assist button to relieve tension on the follower when dropping .22 LR cartridges into the top feed lips.
- Periodically wipe down the polymer housing and internal channel with a dry cloth to prevent rimfire wax, powder residue, and trail dust buildup.
