ZEV BBL17OPTTHDLC Optimized Match Replacement Barrel 9mm Luger 4.49" Black DLC Finish 416R Stainless Steel Material with Dimples & Threading for Glock 17 Gen1-4

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 in 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 which is an ideal material for making match grade barrels because the material allows for the precise cutting of chambers and rifling which results in a more accurate barrel.
