We have just one very nice Colt R0933 M4 Commando machine gun still available. It's been converted to 3-round burst, however, we can convert it back to full-auto at no additional cost if you prefer. This gun is low-mileage and is very nice cosmetic and perfect functional condition. Comes with 4 position sliding buttstock, ARMS BUIS, and the original Colt factory accessory kit with sling, two 20-round aluminum magazines, cleaning rod and brushes, and owners manual. FedEx Ground shipping is $30.00 within CONUS.
