Banking on your desire to improve upon perfection, CMC has introduced its Match Precision Barrel series for Gen 3 & 4 Glock 17, 19 and 34 pistols. CMC says these drop-in Glock barrels are precision-machined from 416R premium grade stainless steel. More in the presser below:

CMC’s Glock Barrels

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.

The barrels are bead blasted for a satin finish. They come in the three finish options listed below. Each is available with or without suppressor threads in 1/2-28 TPI RH.

  • 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

MSRP on these CMC Glock barrels is $210 for the threaded option, and $199 for the non-threaded version.
