tippmann 98 c with expansion chamber, response trigger, xcel barrel, double trigger, rocket cock, psycho ballistics drop.
Makes the gun quieter and eliminates the external moving parts. protects from dirt and paint. makes the gun look sleek. easier and faster to cock then stock handle.
flimsy, the old one is made at of plastic and is very flimsy and occasionally pops back a little. the new aluminum one eliminates all these problems except that you cant use other upgrades like the Ebolt , CAR stock, rva and anything else near the end of the gun.
pretty good overall but if you are going to get one, you should spend the cash and get the aluminum one. if you constantly get shot in the bolt window this is what you need.
