Price is shipped. I got a boneyard apex ambidextrous m4 from evike and I just want to get rid of it. The two problems with it were a broken qd spring guide and a cracked lower receiver. I ordered a krytac qd spring guide but it didn't fit. An a&k qd spring guide worked but I need it for my other gun. Comes with a brand new lightweight full metal piston and all other internals + Receivers + metal rotary hop up and everything else in the pic. I believe the gears are 16:1 ratio but not for sure - they look stronger than stock sintered gears. Gears have already been shimmed (though I didn't test the shim job well enough) and Aoe corrected. Looking to get rid of it fast, priced to sell.
