Parts List. M4E1 lower receiver. CMMG lower parts kit. Rise Armament RA140 trigger. KNS antirotation pins. Magpul K2 grip. Aero Precision milspec carbine buffer system (H1). charging handle and bolt carrier group are not included. I built this lower in 2022 and fired less than 100 rounds through it while testing two different uppers. It was a good "starter" lower for an aspiring armorer. It'll fit the need of someone looking for a reliable lower that doesn't break the bank. Sale in the Fairbanks Borough preferred. Money order or cashier's check only.
