Description
Take your shooting game to the next level and really reach out to some of the farther ranges with this LR-308 build kit. This build kit comes with a parkerized 20″ barrel made of 4150 chrome moly vanadium steel, so you can squeeze every last bit of accuracy out of your rifle possible.
A custom, free-float M-Lok handguard with low-profile gas system improves accuracy and provides plenty of rail estate for your favorite accessories and attachments. The inner workings are handled by a quality, mil-spec CMMG lower parts kit with a crisp, single-stage trigger. Out back, you’ll enjoy a classic six-position M4 buttstock paired with a .308-specific short buffer and spring. It’s everything you need to build a .308-chambered AR that looks and feels like an original AR-10.
