The XM8 was a new body on a g36, it didnt bring anything new to the market, the XM8 has a deserved place, as the g36 would have done the same. you made a great point!
And yes this rifle is the mona lisa of carbines, i hope to see this rifle explode onto the scene unlike the MC-R. then again it used caseless ammo, so no reason why it didnt make into functioning model.
Yes this babe is in GRAW 2, has weavers to mount lights, optics and what not. Comes in ACU grey by the looks of it. Check out IGN or pick up a next gen mag now!
