This is the CA079M M4 Carbine URX3 AEG

The CA079M is a M4 Carbine equipped with a URX3 style front handguard. The URX is the next evolution of the RAS system pioneered by Knights Armament Corp. With the slick slides, the rail allows for a much more comfortable handhold, especially useful for prolonged operations compared to traditional more bulky RAS systems as well as lighter weight. The operator can still reconfigure the slick sides with attachment rails if mission requirements dictate with the predrilled fitments on the URX.

The URX3-8-SIR benefits from the Full metal construction of its receiver and URX3 style front handguard. The unit comes with front and rear “flip-up” back up sights, allowing the use of optics, but retaining iron sights in emergency situations. The 8″ format is ideally suited for FIBUA and CQB. Multi-position “CRANE” stock allows for a better cheek weld, Tango Down styled pistol grip is more comfortable than standard AR-15 grip. Classic Army “Flash Mag” allows the airsofter to deploy maximum firepower with minimum effort.
