ZEV Technologies PRO Match Glock 17 9mm Luger Threaded Pistol Barrel 1-10 Twist 1/2x28 DLC Black. This material provides high tensile strength and toughness to withstand typical chamber pressures while still being highly corrosion resistant. ZEV PRO barrel bores are some of the most precise in the industry. Every barrel is double honed (rough and finish) until a minimum surface finish of 16 RA is reached. During this process the barrels are held to a final dimension of +/- 0.003'' for consistency and accuracy. The barrels are cut rifled and 100percent inspected for groove dimensions and broach finish. Available standard and threaded with 1/2 x 28 suppressor threading for Glock 19 and Glock 17.
