Zaffiri Precision IBS Barrel for Glock 19 Gen 5, Bronze

The Zaffiri Precision IBS Barrel for Glock 19 Gen 5 in bronze (brand part no. BA-G19G5-CP-BN) is a match-grade barrel built to pair with Zaffiri’s Integrated Blowhole System slides, which vent gas up and out through a ported slide to cut felt recoil and muzzle flip. Machined from 416R stainless steel that is stress-relieved and heat-treated, it is rifled with a 1:10 twist rate and finished with a polished feed ramp for smoother feeding across lead, plated, and jacketed bullets. Zaffiri Precision cuts a target crown at the muzzle and an oversized lockup area for a tighter, more consistent barrel-to-slide fit than a factory barrel. Paired with a compatible IBS slide, the barrel and slide are machined together as a matched system for correct port alignment and gas timing.
