This is the second edition of my HALO assault rifle. I've hadn't had the time to redo the AR until now. Some of the improvements include 1.) More black elements near the barrel, 2.) a larger green flashlight button, 3.) a redesigned ammo counter sporting the number 7 instead of 31, 4.) a brand new charging handle for reloading 5). And most prominent a re-designed handle and stock. The stock was the thing I wanted to change most on the original. There is still no removable magazine yet (maybe it could be in a V3). Enjoy the V2.
