Gun Runner Headquarters

It consists of a main lobby (mostly destroyed), the work-shop which has 6-10 reloading benches and a work bench or two. There is a upper floor (i am fairly sure), but for some unapparent reason they attacked and i got the living s*** beaten and shot out of me (DO NOT ATTACK THEM UNLESS YOU ARE ABSOLUTELY SURE YOU CAN HANDLE THE ONSLAUGHT!).So further recon is needed.
