"This was my first time building a lower. This parts kit made it easy for a rookie like me to identify all the pieces. Took me about 45 min to an hour to finish, but everything fit great on my CMMG lower. Thanks, CTD!!"

"Great parts kit for the $$$! Have built a few rifles with this kit and for the $$$, it can't be beat! The trigger pull is really nice for a cheap kit :-)"

"Purchased two of these for a couple of builds. Just finished the first one a week ago. All the parts are solid and perform well. The color coded bags make it easy for the first time builder."

"I can't say anything negative about this parts kit. Everything went in smoothly and I couldn't beat the price at the time I purchased it. CMMG even offers videos on installation and they are great."

"Fast shipping as always, this is my first build and after research decided on this kit, everything went in rather easily. The hardest part on my end was lining up holes, perfect fit into my del-ton lower can't wait to get an upper for it"

"This is as about as good as it gets for a lower parts set..Everything fits good and the trigger action is perfect..For some reason I was missing the trigger spring but I emailed CMMG and they sent me one no questions.."

"All parts fit perfectly in a DPMS lower. MAGPUL PMAG 30 mags slide in without trouble and are secure with little play."

"Nice product. The packaging is sectioned with associated parts in separate pkgs. The box is very small and (about 4x5) and works well to save all those small AR parts in the safe. All the parts were clean and fit very smoothly without any modification of cleanup. Good product."

"My only suggestion would be to buy an upgraded trigger guard before installing. I wish I would have. The trigger guard that comes with it is perfectly fine, just wished it was curved on the bottom to give you a little more room when wearing gloves etc. Overall this lpk fit perfectly in the Stag Arms stripped lower. The trigger is also decent for a mil-spec trigger group. As always great service from CTD."

"This is a great kit for the money. Having the various parts in colored bags make it very easy to assemble. Trigger pull is a standard mil-spec feel. Great service from Cheaper Than Dirt!"
