CMMG lower parts kit is designed for AR-10 lowers, kit includes a pistol grip, fire control trigger, and pins required to complete a stripped lower.
These are some of the most consistent lower parts kits we have ever used. Each and every time I use one of these lower parts kits the pins fit perfectly and the lower assembly goes as planned.
Stop loosing your mind trying to hammer in oversize and out of spec pins, save your lowers finish, save your mental health and buy it right the first time.
We suggest that every family that has an AR keep at least a few spares on hand. This is one of those parts, whether you buy it from us or not, keep spares on hand!
