CMC’s Match Precision Barrels are the ultimate upgrade drop in barrels for Gen 3 & 4 Glock® 17,19 and 34 Pistols. CMC Match Grade barrels are precision machined from Certified, DFARS compliant; pre hardened 416R premium grade stainless steel, to extremely tight tolerances and exacting details. 416R stainless steel is recognized for its corrosion resistance, machinability and high tensile strength; it is the industry standard for premium Match Grade barrel manufacturing. 

CMC’s 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.

CMC 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.

Barrels are bead blasted to create a satin finish prior to plating and are available in 3 finish options.

• Stainless , uniform Satin Blast Finish with ultra- low friction hBN (Hexagonal Boron Nitride) Bore & Chamber
• Bronze TiCN, with ultra low friction hBN (Hexagonal Boron Nitride) Bore & Chamber
• Black DLC, with ultra low friction hBN (Hexagonal Boron Nitride) Bore & Chamber

User friendly, CMC barrels are drop in; they do not require gunsmith assembly.
