Colt M4 Carbine
LGS was playing a trick on me, by saying I was the first one to received the first polymer lower from Colt he's ever seen! Got my attention real quick. They handed me a Colt m4 lower that was perfect, in everyway. Not a polymer, but aluminum, Great job as always AU.

Colt lower
The colt lower is always solid, but mine had unnatural ware to the coating in the magwell which is very weird for something that is a new factory lower, was offered $20 discount so that was okay I guess

OEM . Upgraded laser markings
To tell you the truth these lowers are solid , most enthusiasts criticize de modern upgrade to laser markings/ but this is the way of the future , quality is present and all tolerance is what to be expected from a milspec manufacturer.

fantastic lower
First id like to compliment a.a on being a great retailer. I had a few questions which were answered promptly by email. Secondly this was probably the smoothest ffl purchase i have made. I believe my item shipped same day and arrived in 3 business days! The colt lower itself is fantastic. It has a mixture of cage code and unmarked parts that are all of top quality and fit. It is interesting to see the way colt is evolving. H buffer included. Get one while they are available
