ZEV BBL17OPTBRZ Optimized Match Grade 9mm Luger, Compatible w/Glock 17 Gen1-4, 4.49″ Bronze PVD 416R Stainless Steel Dimpled Barrel

ZEV Technologies Optimized Match Barrels have been redesigned for improved performance compatibility. Enhanced features include a recessed target crown, a new match chamber and a stylized barrel hood with caliber and model engravings and a loaded chamber indicator. ZEVs proprietary broach cut 1:14 left hand twist rifling was developed to create the most accurate Glock aftermarket barrel available, and testing confirms a significant increase in accuracy over factory barrels in all standard bullet weights. Manufactured from 416R stainless steel material allows for the precise cutting of chambers and rifling which results in a more accurate barrel.
