Colt M4 Carbine Lower Receiver Assembly
I must say I was surprised to receive a Colt M4 Carbine Lower in perfect condition. Colt is traditionally not known for perfect finish but more for their M4 rifle issued to infantry soldiers since Viet Nam through 2021. The Colt M4 Carbine rifle is as American as baseball, hot dogs, hot apple pie and freedom. We should never allow them to be taken from us. Our AR15 platform is the current teeth to our 2nd amendment rights however one needs to dress it up for their personal safety if needed. Their is nothing sexier then a stripped AR15 lower. From there we can make her / him just how we want. That American!!!!

M4 Lower for my CCU 6960 build.
Perfect transaction. Item is in near mint condition. Apparently I'm one of the few luck ones who made the purchase prior to the Colt lower receivers being out of stock. Thank you AU for the assistance in a easy FFL transaction.
