With proprietary in-housing machining and quality control inspection, CMC is able to produce barrels with unmatched precision. This Glock 17 fluted barrel features an enhanced slide fit and lock up to give it improved accuracy, with the smoothest bore possible and a max roughness average of 12. Its finished bore dimensions are held to +/- 0.0005” tolerance to give a nominal groove and bore, but those dimensions are uniform as close as 0.0002” for consistent, accurate performance again and again.
Barrel production starts with pre-hardened 416R stainless steel that’s then stress relieved after rifling to a final hardness of 38-42 Rockwell C before the final profile is completed. A bead blast finish gives the barrel a satin look before plating. This drop-in barrel won’t require gunsmithing, so you can finish out your build quickly and efficiently.
