QC10 .40 S&W barrels are threaded for the attachment of flash hiders, suppressors,* and accessories, and finished with a nearly indestructible protective treatment. Our barrels have a medium outer profile and come in a variety of lengths to suit any need.

 

Note: Barrels are measured from the end of the muzzle to the end of the breech/feed ramp. Approximately 1″ of the barrel rests inside the upper receiver upon installation, resulting in an installed length of 1″ less than listed overall length.


*The installation of a pistol-caliber suppressor requires the use of a fixed barrel spacer. See your suppressor manufacturer for information on the requirements of your particular model.
