Airsoft GI get the E&L Airsoft's AR AEGs in stock and for this overview they cover the E&L MK18 AEG... "E&L's M4 MK18 Mod 1 is the newest in the line of M4 rifles from E&L Airsoft. Made entirely out of metal, save for the stock and pistol grip, the MK18 is a very solid rifle. The rail featured on the MK18 is, as the name of the rifle suggests, the MK18 RIS 2 quad rail. This rail, and overall, upper receiver group is most recognizable from use within US Special Forces units. The Barrel on this rifle is a slick 10.5 inches long, and serves to keep the rifle compact and relatively lightweight, while maintaining a useful length for ranged engagements.

The gearbox on the E&L M4s are every bit as durable as their AK line, with a very solid, steel gearbox shell and a one piece Cylinder assembly, an M120 spring, a nozzle with an O-ring for better seal, 9mm bushings and a quick change spring system are just some of the very solid parts included in the E&L Elite line of rifles."
