All the parts I needed
by John -
This was my 1st build and I did not really know what I was doing when I started, but this parts kit made it easy with how it was packaged and labeled. Everything fit and functions properly.
Great price for a LPK
by Andrew -
I purchased two of these LPKs and did not experience any problems with the safety selectors. I like the way the parts are separated in the blister pack. When you open the blister pack make sure it's face down, so the parts stay in their places.
Great lpk

No fuss no frills just great parts from a reliable company.
You get what you pay for
by Daniel
It worked but I'll be looking for better in the future. The magazine latch holds a magazine but wouldn't lock onto the armorers block I have. I compared it to a bushmaster lower and the magazine catch is undersized in the CMMG compared to bushmaster. The takedown pins are not flat on the ends. Roll pin for trigger guard and the trigger guard are not included.
My go to lower build kit.
by CheeseWeenie
This has become my favorite lower build kit. I have tried an Aero kit on my recent Aero lowers and it isn't the same quality as the CMMG. The only thing that the Aero kit had over this one.. The little rear screw to hold the rear takedown spring and pin in place. If the CMMG had that feature, it would be absolutely perfect.
Close, but not right
by Ken -
Everything fit and functioned as expected except the safety selector. Even after using proper lubrication and giving it time to break in the safety doesn't operate smoothly. It's rather annoying and I'll wind up changing it. Great price, especially when it's on sale but I would suggest picking a different kit.
OUTSTANDING

Great Quality, Extremely fast shipping and unparalleled customer service from PA. Thanks!
Excelent fit
by Richard -
4th set. All the parts are within specs, good finish. The layout of the package is very nice in that you can verify all parts are present at the first glance. I will continue to buy this set.
Selector Switch Won't Fit
by Chris -
I've done a few builds with the CMMG Lower Parts Kit. In the past these have been reliable, but lately the selector switches are way out of spec, and won't fit in the receivers. And in a couple of them the takedown detent springs are slightly too long.
BAD SELECTOR
by Sion -
Parts kit is good except for a cheap finish on the magazine release button and the safety selector is out of spec by .10mm, scratched the finish on my lower.
