If you're starting an LR-308 build, you'll need a lower parts kit. How about an LPK with an upgraded grip?. Aero Precision's M5 Enhanced .308 Lower Parts Kit provides just that: Quality, mil-spec internals for your stripped lower receiver, or finished .308 80% lower, plus a Magpul MOE pistol grip.
NOTE: Because of minor variances in the M5 receiver's design, the M5 .308 LPK's takedown and pivot pins protrude from other .308-type receivers slightly more. This does not affect functionality in any way.
