Doesn't have all parts you need to build a lower
The parts that this contains are fine, quality parts. It's a bit misleading to call it a Lower Parts Kit. Other lower parts kits I've bought had all the parts you need to build a lower, as one might imagine from the name lower parts kit. The fact that this one doesn't have a trigger guard or grip screw is bewildering. Ironically it does come with trigger pins so now I have an extra set of those since the trigger I bought also had them, but I have a rifle with no grip or trigger guard. Shaking my head....

Bang for the buck.
Only wish it came with a trigger guard. Otherwise everything fit and no surprises.

Good fit and function
I didn’t have any problems with fit and the parts have held up well I would buy again when needed.

This @cmmg is a very nice Lower Parts Kit, minus grip, and fire control group. This is the type of kit I prefer, due to using at least a NIB Trigger upgrade with @JPsprings,. Or a @Lantac or something in the @cmctriggers family. So you get all the parts you need, and none of the excess you don't. @palmettostatearmory had these in and priced right, so I got 3 sets and other quality products.
Great Kit for Novice and GunSmith alike.!
