Tippmann 98 with Full Boar Rear Cocking and Expansion Chamber
Removes the charging handle, which means no more scraped fingers, and clipping trees and bunkers
Amazing quieting effect. The marker now has about 1/2 the sound.
Seems to be smoother action.
Plastic cover keeps everything out of the bolt area. You can put the marker down on the ground without worrying about crud getting into the action.
Looks sooo cool.
Poor instructions for installation - no diagram
Little aluminium grip on the cocking rod works loose if you don't put lock tite or teflon on the threads
Beaver tail sticks out quite far in the back - keeps hitting my mask.
Hard to cock the action with slippery fingers
Worth every penny for me. The marker is much quieter, and I don't have to worry about snagging the cocking handle. The person below me who said the bolts of the port cover were hitting the hammer is right, but he did not read the installation instructions, which clearly say you have to crank the screws to force the bolts into the slot, "shaping" them to fit the slot. I'm giving it an 8 for the lack of a diagram (I still don't know where to put the little cloth piece).
