I have a AR-10 .243 Win that i have used for thermal predator hunting. The rifle has a 24" Stainless Barrel, rise armament 3lb 2 stage trigger, heavier buffer, and an Aero Adjustable gas block so that you can run a can. The rifle is great, i shoot 75 grain federals out of it with a 200yd zero i hit point of aim out to 400yds. I have another build in mind and want to get back to a AR-15. Asking what i have in it. $750 or trade for a 6mm ARC / 6.5 Grendel in an AR platform
