The NLX LPK15 Lower Parts Kit After trying several lower parts from multiple manufacturers over the years, Next Level Armament always came back to CMMG. Whether building rifles here at Next Level, or building our own personal rifles, CMMG parts are hands-down our first choice. The quality and consistency you find in their parts elevates them above all other suppliers. While you can find lower priced kits out there, CMMG is made in the USA, not just bulk parts from overseas packaged in house. Since CMMG is all we use, we partnered with them for the NLX LPK15 Lower Parts Kit to obtain a high quality, yet affordable, Mil-spec Lower Parts Kit for our customers. Add this parts kit to one of our lower receivers for a quality base to your rifle. This lower parts kit contains all the parts you need to get started on your next AR15 build, packaged in convenient, color-coded packets to simplify assembly.
