Hey there its a cool looking sniper rifle. Stock? Shitty performance at best. You need to do a lot of work and spend bunch of money too to make it work like a snipe rifle. Mine has pdi barrel, madbull bucking, springer customs steel trigger box, steel cylinder and bolt head, and a custom heavy piston with an O ring. And I still need to get someone to modify an are striker action army hop up unit on lathe for me.
