Lower Kit
Quick shipping. Good price. I like the lower kit the parts are grouped together in separate plastic bags. Make them easier to identify.
Good product lines.

Parts kit
Great quality!
my go to LPK's
I like these LPK's CMMG does a good job, parts are always consistent. I don't do fancy-pants triggers, at 5'11" and 180 pounds I think I should be able to pull a mil-spec trigger without wiggling the rifle and I like these triggers.
cmmg lower parts kit
I have used these parts kits before and i really like them.
Fantastic Value LPK!
It comes with dimpled takedown pins! This was one thing I thought I might be compromising when going for this kit over something like the Geissele Ultra Duty kit but no. Also I love the ambi safety, it reminds me of the LMT ambi safety I have on my MARS. Because of the quality parts included I feel like Im wasting less since Im getting my creature comforts on the front end with this kit. This kit paired with a LaRue MBT trigger is a killer value.
Easy install but watch Brownells video
Okay first thing the safety install comes after the hammer! OMG this was my first ever lower build and I followed the manufacturer video...a bit frustrating but at least it was good practice. Make sure you watch Brownells video at the hammer section they will guide you correctly. The product is awesome and solid! Easy install yes and even for first timers! This was installed in a Spikes Tactical Crusader lower. So the safety spring goes in different than the video. If I can figure out anyone can. I still give 5 stars for the quality.
Nice Parts Kit
I am overall very pleased with this parts kit. All the parts look good and appear to be high quality. The trigger is surprisingly nice for a standard mil-spec part, definitely one of the best mil-spec triggers I have used. It has a very smooth pull and a clean break. The takedown pins are a little longer and dimpled to make it easier to push them out with a tool or bullet tip. The takedown pin detents were very stiff and required a decent amount of force to push the pins out but they eventually broke in. Same issue with the safety selector detent. It might not be a bad idea to snip one or two coils off the detent springs. The only part that caused me issue was the bolt catch roll pin. I think it is oversized and it is a real chore to install. It will fit, it just takes patience and a steady hand. I was installing this parts kit on an Aero Precision lower receiver, by the way. I would certainly buy this parts kit again. I think the price and quality makes it a great value if you are doing a basic build and will use all the parts.
Good Quality parts
Bought two of these kits so far and both fit the Aero Precision lower receivers i purchased from Brownells perfectly. It is a good quality kit that meets or exceeds military specifications. Will purchase many more in the future.
