ZEV Technologies

ZEV Technologies Optimized Match Barrels have been redesigned for improved performance and Gen5 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. - ZEV's 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. - Available in Black DLC and Bronze. - G19 and G17 models are available either 1/2x28 threaded or non-threaded. - G34 models are non-threaded only.
