Videos tagged with Island Cut Slide

This video from Civilian Tactical provides an expert look at ported barrels, specifically the Derya Arms DY9's 'island cut' design. The host, a specialized firearms content creator, explains the physics behind how porting reduces muzzle flip by venting gases upward, though it can slightly decrease bullet velocity. The demonstration highlights a significant reduction in muzzle rise during rapid fire, making the firearm shoot flatter, but also notes an increase in noise.
