Who This Is For
This kit is ideal for experienced AR-308 builders and hobbyists who already have a preferred trigger group and pistol grip in mind.

Frequently Asked Questions
What parts are included in this LPK if the trigger group and grip are excluded?
This CMMG LPK includes all the remaining essential lower parts needed to complete an LR-308 lower receiver, such as the bolt catch, magazine catch, takedown and pivot pins, trigger guard, safety selector, and associated springs and detents. The fire control group (trigger, hammer, disconnector) and pistol grip are intentionally omitted so builders can select their own preferred components.
Will this kit work with non-CMMG LR-308 lowers from other manufacturers?
Yes — in addition to CMMG Mk3 pattern lowers, this kit is compatible with most standard LR-308 type lowers from other manufacturers. However, fit can vary slightly between brands due to minor dimensional differences, so it is always a good idea to confirm compatibility with your specific lower before completing your build.
What trigger group do you recommend pairing with this kit?
That depends on your intended use. For general-purpose or duty-style builds, a standard mil-spec .308 trigger group works well. For precision or long-range shooting, consider a drop-in aftermarket trigger such as those from Geissele, CMC, or LaRue Tactical. Just ensure any trigger group you choose is rated for the LR-308 / AR-10 platform, as AR-15 trigger components are not compatible.
