Frequently Asked Questions
Will this LPK fit my non-CMMG LR-308 lower receiver?
Yes. The CMMG ZEROED Mk3 LPK is designed to be compatible with CMMG Mk3 lowers and most standard LR-308/AR-10 pattern lower receivers. However, due to the lack of full industry standardization in the LR-308 platform, it's always recommended to verify your specific lower's compatibility before purchasing, as some proprietary designs may have slight dimensional differences.
Does this kit include a trigger guard?
The CMMG ZEROED Mk3 LPK includes the core components needed to complete a lower build — trigger, hammer, disconnector, bolt catch, magazine catch, safety selector, pistol grip, and pivot/takedown pins. A separate trigger guard may need to be sourced if your lower receiver does not have an integral trigger guard, as it is not listed among the included components.
Is this a mil-spec trigger group or an upgraded match trigger?
The ZEROED LPK includes a standard mil-spec style trigger group consisting of the trigger, hammer, disconnector, and their respective springs and retaining pins. It is designed for reliable, consistent function rather than competition-grade performance. Shooters seeking a lighter pull or shorter reset may wish to upgrade the trigger group separately after completing their build with this kit.
