I am new to owning my own gear, only this year, in the past I was a 2-3 time a year player renting gear. Now I am full into it with my son. We purchased Cronus Tactical edition guns and are happy with them. However I was hoping to add a different shroud on mine. The 'silencer' version that came with mine, doesnt allow me to add any extras due to no Piccatinny rails. Have been looking everywhere online to see if I need any special type one to fit properly on my gun.
