      Colt M4 lower

      Posted by Donald A Hooper on 8th Dec 2025

      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.

      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

      Posted by Yukon58 on 20th Jul 2025

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