Barrel Finish

This barrel is available with the following finish options:

Machine Finish: Barrel is in its unpolished, "as-machined" state and will show light turning marks and slight imperfections.

Light Polish: Barrel receives a light "brushed" finish. This leaves the surface uniform and removes most machine marks and blemishes.

High-Grade Polish: Barrel is polished to a reflective finish on the same level as our complete rifles and barrel kits.

Black Teflon™: Barrel receives a uniform low-shine black coating.

Tactical Finish: Barrel is blasted to a non-reflective, matte gray finish.
