    Good choice for all-around rifle builds

    Posted by Diz on July 6, 2026

    This is a very good choice for hard use, all-around rifle build, especially if you may see occasional strings of rapid fire, and/or suppressed firing schedules. The chrome lining protects better from accelerated chamber wear. The phosphate finish is the perfect base for your favorite coating. And the 12.5" length is damn-near perfect for the general purpose rifle.
