CMMG AR-15 Lower Receiver Parts Kit LPK

I purchased this kit to install on my stag arms lower and everything fit like a glove. It doesn't come with instructions but if you have a little bit of mechanics knowledge its a piece of cake. The parts come with a little card that describes whats in each colored package it makes knowing which spring is which much easier for a first time builder. I also purchased a DPMS lower kit for my other stag arms lower and it was a bit of a pain. Parts fit almost too tight. If your not sure which to get I highly suggest this kit. Super easy much high grade parts and the fit is perfect. I don't have special tools to build ARs and this was a breeze just need a hammer to tap in a couple little pins but that's it!
