most shockers are shocker threaded - apart from some pl's i believe which chose to use cocker threads - so im not sure it would if it is just a stockBoyblue666, the proto front and dye ultralite back are still up for sale.
purepaintballer, the fits my ego (an autococker thread) so i presume it will fit your shocker.
i would prefer to sell the barrel front and back together.
