CMC Triggers Match Precision Glock 17 Barrel – Black DLC, Non-Threaded

Description

This CMC Match Precision Barrel is built for owners who want their Glock 17 to shoot tighter groups without swapping out the whole pistol. It slides right into your existing Gen 3 or Gen 4 Glock 17, no fitting or gunsmith work needed, and picks up where the factory barrel leaves off with a match grade chamber and a bore that's been finished to a much finer standard than what ships stock.

What Makes This Match Precision Barrel Different

CMC starts with certified, pre-hardened 416R stainless steel, the same alloy match barrel makers have leaned on for years because it resists corrosion, machines cleanly, and holds up under repeated firing. After the barrel is rifled, it goes through a stress relieving process that brings it to a final hardness of 38-42 Rockwell C before the profile work is finished. That extra step matters for long term accuracy since it keeps the steel from moving or warping as it heats up on the range.

Rifling and Chamber Work Behind the Glock 17 Barrel

Inside, you're looking at 6-groove cut rifling with a 1:10 right hand twist, and the bore gets double honed in both a rough and finish pass to bring roughness down to a max RA of 12. The chamber is cut to SAAMI match grade spec and finished to a max RA of 16, with bore dimensions held to plus or minus 0.0005 inch and kept uniform within 0.0002 inch from one barrel to the next. That kind of consistency is what lets a drop-in barrel actually compete with a full custom build.

Black DLC Finish and Straight Fluted Profile

This particular version comes bead blasted for a satin look before getting coated in Black DLC, with an hBN (hexagonal boron nitride) treatment on the bore and chamber that keeps friction low and fouling easier to clean out. The straight flutes cut into the barrel aren't just for looks either, they shave a bit of weight while giving the gun a more distinct profile. Since this is the non-threaded version, it keeps things simple for owners who aren't running a suppressor or compensator and just want a cleaner, more accurate barrel in their Glock 17.
