      Colt Commando Lower

      Posted by Randy Sengbusch on 5th Sep 2026

      Great lower, however does have the sear block. The engravings all over the lower are laser engraved (which is as advertised) I was looking for a stamped LE lower. But this one was available and in-stock. Price seemed steep but is basically a complete lower with all colt parts so its a pretty good deal with that in mind.

      M4 Commando Lower

      Posted by Anthony on 17th Aug 2026

      I haven't had a chance to shoot with it yet, but I'm sure it'll perform well. As always, the customer service was excellent. I've bought from Arms Unlimited before and had a great experience. The price for the Commando was pretty good too; couldn't beat it. Just waiting to get it to the range.

      I have "M4 Carbine" marked lowers, and now I get to add a "M4 Commando" marked lower to my collection. Grab them while you can.
