Why “Proof-Tested” Matters

In the world of big-bore handguns, safety is paramount. A proof-tested Glock .50 upper ensures that the barrel and slide geometry can withstand 25–30% more pressure than standard rounds. This process identifies any microscopic defects in the steel, providing you with a reliable, high-performance firearm that you can trust in any environment.

Optimized for Recoil Management

Firing a .50 caliber round from a Glock frame is an experience like no other. Our uppers are weighted and balanced to help mitigate muzzle flip, allowing for faster follow-up shots and a more comfortable shooting experience compared to unweighted conversion kits.
