      Colt M4 COMMANDO

      Posted by Ray vanderpool on 4th Mar 2026

      Only gave 4 stars because shipping and delivery took so long almost 3 weeks they did email me back every time I asked about my order. It finely arrived at my work/FFL in good condition and I'm very happy with the lower receiver.

      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.....
