yes its simple pull bolt out of receiver. now look for the fake screw not quite halfway back, punch the PIN out of the bolt (not the fake screw but the pin thats closest to it). now there is no spring tension on the nozzle/piston asm. the little plastic rectangle on the side needs to be removed next, all you do is take a small flat head screwdriver and from the inside of the bolt push the back of the rectangle out. it will push out slightly now you have to slide it towards the back of the bolt and gently push out with screw driver. the piece is a guide/retainer and is about twice the length that you actually see. now the whole nozzle/piston asm will come right out. the rest of the tear down is simple theres a small pin at the back that holds the piston cup asm on, push out gently and put to side. nothing will have come off at this point as there is on last screw/pin to remove. this is the one halfway down the nozzle that holds the return spring in as well as the floating valve. remove and it is all apart.
