Selling my Marui M4A1 GBBR with five magazines. The gun shoots great and cycles cleanly. Internally, it looks great (there's normal wear on the bolt carrier from hitting the hammer). Externally, the Colt markings are untouched and the only real issue is a chip at the bottom of the RAS. All magazines feed and do not leak. Looking for $550 shipped in a hard case within CONUS.
