The Valken Alloy Series M4 MK3 AEG Black is an all metal airsoft gun with SHS gearbox guts newly made in 2017.  We really like this gun!  It's a solid airsoft design that most airsofters desire in an out-of-the-box base configuration.  For a high-end gun, this is one of the 'best bang for buck' airsoft guns made.  We definitely recommend it.  Now on to specifics:

This is an all metal AEG gun, featuring a 15 inch long aluminum M-Lok rail system, metal upper and lower receiver, and many other parts.  Buffer tube is milspec, with its 6 position crane stock, and metal sling attachment point.  14mm CCW outer metal free floating barrel.  The bolt catch is fully functional.  Flip up sights included (we recommend adding a sight).  Magazine is a 450-round hicap all metal mag.

Internal upgrades feature:  one-piece hop up chamber, micro trigger switch (not a mosfet, but similar; can use a LiPo), SHS upgraded steel gears 18:1 ratio, SHS piston with steel teeth (2nd tooth removed), steel one piece 6.03mm inner barrel, upgraded wiring, 8mm bearings V2 metal gearbox, quick change spring gearbox.

FPS:  380-390 w/.20g BBs. - The gearbox is a quick change spring system if you ever want to raise or lower its FPS.

One year warranty for defects from Valken!
