For a long time WE's specialty when it came to rifles were their line of ultra-realistic Gas Blow Back Rifles and they have since dominated that arena with their constantly innovative, hard hitting products. Constructed in the same manner of their realistic gas blow back rifle line, WE's M4 AEG features a metal delta ring, mil-spec metal buffer tube, metal hop-up unit, and a full metal gearbox. Just about the only thing not metal in this rifle with the nylon fiber grip and LE stock. Coming to you in a matte black finish to compliment its classic carbine configuration with its polymer hand guards, metal front post and metal barrel, collapsible stock, and detectable carry handle. Detaching the carry handle will reveal its Rail Accessory System (RAS) along the top length of the gun from where the carry handle once sat. In the place of it could be red dot sights, scopes, backup iron sights, and other accessories that can be attached onto the gun to meet any combat situation. 

The gearbox itself features a spring release design that decompresses the gun's gearbox spring when set on SAFE, increasing the life and power output of your gun. A feature seen on only a handful of airsoft guns ever, however none as cleverly and intuitively designed to be activated via the SAFETY selector. The bolt itself will lock back when the charging handle is pulled to easily access and adjust the hop-up as required while a tap on the bolt release paddle will lock the bolt forward with a nice metal clink. 

Internally, the WE Full Metal M4-A1 features a reinforced 8mm gearbox with a high RPM motor, nylon polymer piston, and steel gear set. Working off the version 2 gearbox design, it is fully compatible and upgradable like most M4's on the market for one to fine tune the performance of the rifle to their needs. 

All this is topped off with the famous Frog Skeleton that has come to represent the Navy Seals themselves. An excellently piece of equipment coming to you in its compact CQB-length configuration and matte black finish.
