Airsoft GI Dune Knight M4 Carbine (Blowback Version)

This thing is sick! It is a custom G&G Combat Machine with a crane stock, a 10' URX rail, flip up sights, and a very good ROF with a 9.6v battery for stock internals. The dust cover never stays up though, and it really pisses me off..........


Note: Gun does not come with "Zombie Killer" barrel extension/mock suppressor.
