Our barrels are 6 groove, cut rifled, 1:10 twist right hand, fully inspected, double honed (rough and finish) to produce a bore with a max roughness average (RA) of 12. Chambers are match grade SAAMI specification, precision cut and polished to a maximum roughness average (RA) of 16. The pre-hardened 416R stainless steel is stress relieved to a proprietary recipe after rifling and final hardness is 38-42 Rockwell C before final shaping and profiling work is done. Final dimension are held to a +/- 0.0002″ deviation for maximum consistency, accuracy and quality.
