ZEV Technologies V2 Match Barrels have been redesigned for improved performance. Enhanced features include a recessed target crown, a new match chamber, a stylized barrel hood with caliber engravings, and a loaded chamber indicator. The V2 Match Barrels have ZEV's proprietary broach cut 1 in 14" left hand twist rifling which was developed to create the most accurate Glock aftermarket barrel available. ZEV's testing had confirmed 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 due to the precise cutting of chambers and rifling which results in a more accurate barrel.
