CMCs propriety In house machining production and Quality control inspection process's allow us to attain an ultra-precise barrel with enhanced slide fit & lock up for improved accuracy. - Our barrels are 6 groove cut rifled 1:10 Twist Right Hand fully QC inspected double honed (rough and finish) to produce the smoothest bore possible with a Max Roughness Average (RA) of 12. Finished bore dimensions are held to +/- 0.0005 tolerance from nominal groove and bore dimensions but the dimensions are uniform to within 0.0002 for maximum consistency accuracy and quality. - SAAMI Match Grade specification chambers precision cut and finished to a maximum Roughness Average (RA) of 16. The pre hardened 416R stainless steel is stress relieved to an exacting recipe after rifling and final hardness is 38-42 Rockwell C before final barrel profile machining is completed. - Bronze TiCN with ultra low friction hBN (Hexagonal Boron Nitride) Bore & Chamber - User friendly our barrels are drop in; they do not require gunsmith assembly. - These are an affordable ultra accurate durable upgrade to your existing Glock 1719 or 34 factory barrel. - Barrels are available with and without suppressor threads in 1/2-28 TPI RH - Our Barrels are straight fluted for aesthetic purposes - 100% Manufactured in house in The Great State of Texas
