Build your LR-308 rifle with this kit, and then really stretch out with your shots fired and go the distance. Up close, they'll be blinded by the luster of your stainless steel barrel and compensator, while off in the distance they'll hear the clang of your lead slamming steel. This build kit comes with a 20" match barrel made of416R stainless steel, so you can count on it lasting the entire life of your LR-308.

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.
