CMMG Complete AR-15 Lower Receiver Parts Kit
Ratings & Reviews
6.8 spc build
by Hector Medina
I am very happy with the CMMG floor parts kit that I bought for my AR build. All the parts were in separate color-coded bags for ease-of-use.
Excellent service from PA

...now for the kit. Excellent machining, roll pins were beveled which is nice, takedown pins were slightly longer than most milspec with indentions on the ends. Really nice.But...my kit had two bolt catch pins...and no bolt catch plunger. Sonofabitch. So, my build came to a halt. $1.49 for a plunger, and $7.01 s/h (since standard USPS is "running 3 weeks behind" and I don't want to keep dragging this build on) kinda leaves a bad taste in my mouth for CMMG even though the LPK is nice.
High quality LPK
by Charles K.
After owning factory assembled AR, I purchased the CMMG LPK for my first AR build. This LPK does not disappoint. All parts were high quality and accounted for. The separation of parts into groups, in color coded pouches, not only simplifies assembly, it helps you stay organized. I will definitely purchase this LPK for my next build. Thank you CMMG and Primary Arms.
my first build

CMMG always does it RIGHT!
by Steven Neal
As ALWAYS, CMMG offers some of the best items and of course, PRIMARY ensures we get it at THE BEST PRICE and FAAAAAST SHIPPING!I have continued to use CMMG parts, UPPERS and enjoy their customer service for YEARS! With MANY great brands out, I get VERY GOOD quality and run this stuff every bit as much as I run my 'Veske, Knights and the others COUNT ON for a rifle that I USE! SURE, you can not clean them as much, put anything thru them, set them up for light, or heavy duty, and NEVER worry about performance.I build and assemble all of my rifles using and maintaining with TW-25B and KNOW that a lot of it comes from knowledge and proper maintenance. SO WHY BUY CHEAP brands, when you can buy great brands with the best prices and count on them when the engagement and threat is REAL!Thanks AGAIN, primary!
Another LPK, yawn
by Al Rayski
As expected, nothing great or sub-par. Nice packaging / arrangement. Only comment is this trigger group probably has the most travel of any milspec trigger I've put together.
CMMG Lower Receiver Parts Kit LPK for AR-15 CMMG55
by ROBERT G
as usual CMMG makes life easier for DIY's.
by Vladimer Garcia
Awesome product except for shipping , it took them a week before it arrive.
Being that the parts come seperated in different colored bags makes assembly much easier.
Excellent fit and finish, super well organized.
Best LPK I've used so far (about 20 lowers built to date). The trigger/hammer sear surfaces are nicely polished and it's a dammed good trigger out of the box, dare I say it's as good as most upgrade trigger groups? Feels as good as an ALG Advanced Combat Trigger.The fact that they organize all the little parts in color coded bags is just pure class, appreciate the extra effort.
Great product, excellent price

by Mark Shawhan
Good parts....awesome trigger. Very smooth trigger pull. Smoother than any Colt or FN I've used at work and smoother than my Sig and Bushmaster stock triggers.
