Rock River Arms 18" stainless bull barrel upper w/free float handguard, Cavalry arms polymer lower. I'm the second owner on both halves, so I'm not sure of the round count. I haven't actually had it to the range yet. It comes with two new C Products 20rd mags and one used 30rd. I also have 150rds. of .223 to go with it. I also have some brass to throw in, can't remember how much right now, I'll have to do a count. The Trijicon that's on it isn't included but I do have it for sale in the optics section and would cut someone a deal if they wanted both. I'd like to get $875 for the gun, mags and ammo. I'd consider selling the upper separately and keeping the rest. Trade interests Glock 29(10mm) SF model only though AK rifle or pistol Marlin lever actions, especially an 1894 in .44 mag or models preceding the 336 Combloc handguns Or?
