Zev Glock 19 Gen 1-5 Pro Match Barrel Bronze- Threaded 1/2 x 28

The PRO barrel line features extremely tight tolerances that have been manufactured with pre-hardened chromium stainless steel (416R). Originally designed for use in Match Grade rifle barrels. The hardened chromium stainless steel provides high tensile strength and toughness that withstands 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 100% inspected for groove dimensions and broach finish. Available standard and threaded with 1/2 x 28 suppressor threading for Glock 19 and Glock 17.
