GLOCK® Compatible Barrels

MOA-capable barrels for your Gen3 GLOCK® or completed P80 frame.

That's why we're happy to offer up these precision-machined, high-grade GLOCK®-compatible barrels for your 80% polymer frame or existing Gen3 GLOCK® platform. Available barrels are made from either 4150 Chromoly (mil-spec steel) or 416R Crucible stainless. These two alloys comprise two of the highest-quality gun barrel steels on the market, ensuring superior barrel life and accuracy under intense fire.
