Colt M4 lower
Arrived quickly, we'll packaged. I gave 3 stars due to several scuff marks and small scratches in a few places on the magwell area and near the firing selector.

Colt M4 Commando Lower Receiver
My M4 Commando lower shipped very quickly and was in mint condition. Perfect start to my next Colt build up.

A++++ Perfect as always
These Commando marked lowers are not that easy to find. They will be in greater demand if/when the SBR/SBS items are legalized in 2026.....

Great Start
Superb start for a new build! Nothing says M4 like an original Colt Commando. Can't wait to build this one out. Maybe Retro!

MY Favorite Lower
This is my second Colt Commander Lower that I have purchased from AU and I couldn’t be happier with the service and price. The lower is as advertised and arrived in perfect condition Thank You AU as always.

Colt M4 Commando SBR
First of all, the fact that Arms Unlimited has the supply of such a rare piece is just awesome. They always have the hard to find goodies that no one else can get. The lower arrived at my FFL in perfect condition and looks so sick. It is the perfect addition to my safe. The people at Arms Unlimited are great and their website is straightforward. The whole process was a piece of cake, even for an SBR. 10/10, highly recommend.
