It looks great on your gun and adds stability when moving and shooting. The only problem that i have is its hard to aim when you have a mask on. Its durable, ive smashed it into the ground a few times going into a prone position and havent had a problem with it. its really easy to install on the gun, its just like replacing the end cap. another small problem i have is tightening the ring to keep it from moving when its on the gun.
Great add on for a tippmann 98, a little expensive but its still a good add on.
