The CMMG LPK is a go-to for my builds. I always keep a couple of these in my spare parts box. It's a great lower parts kit, comes with everything you need to build out your stripped lower (for me, minus the FCG and grip). I really like CMMGs take down pins and the rest of the parts are pretty good as well. For the price you can beat it. I highly recommend this LPK.

This is my preferred lower parts kit for my Silencerco lowers. I’ve never had missing parts as reported by some other users (Though I wonder if that was a shipping issue)
Buy this kit with confidence.

I was building a rifle from scratch, but I had planned to use a drop in trigger. So I didn't want Parts like the trigger group or too many spare parts. I would say that, despite just being standard Parts, they just seem a little more high quality than a basic Milspec kit. Just subtle details that make the firearm more pleasurable to use. Still, I didn't buy it because they are slightly nicer. I just trust CMMG to make parts that fit well and work. While there are cheaper kits that can do the job, these do inspire confidence. If you need a minimal parts kit that you can fully trust, this might be the right kit to buy.
Pros:
- reliable
- Well organized
- Good tolerances
Best Used for:
- Replacement parts
- Building a rifle
Would recommend: Yes

Lo e the deal. Good to have spare parts for an AR15.You really can't buy these AR15 lower parts in the stores,just a few. Built another and of course the spring flies out somewhere. I'm sure it's happened to many of us. Lol

These mil-spec parts all fit perfectly in my lightweight build. Finish and size were all within spec. I know CMMG makes high quality products and that was the main influence in my choice to use them. The price isn’t the lowest but doesn’t break the bank. I’m sure I could have paid 20 bucks less, but 20 bucks is a small price to pay for peace of mind.
