Why might competition shooters replace factory Glock barrels with aftermarket barrels that have rifling design featuring sharper edges?

• A. To Enhance Accuracy in Long-Range Shooting
• B. To Improve Overall Durability
• C. To Prevent Buildup of Excess Fouling from Lead Projectiles
• D. To Reduce Recoil

Answer: (C)

Sharper-edged rifling is used because lead bullets tend to leave sticky fouling in the bore, which degrades accuracy as the match goes on. The design with sharper edges helps scrape or shear lead deposits away as the bullet engages the rifling, so the bore stays cleaner and the bullet leaves the muzzle with more consistent dimensions. That consistency is crucial for repeatable groups in competition shooting. The goal isn’t to change recoil or make the barrel last longer; it’s to control lead fouling and maintain accuracy between cleanings.
