Here's your SSII.
Unscrew the pump handle. The screws are the nice big screws that the SF and Crossbow have; they come free easily.
Unscrew the rest and crack 'er open.
Now take the plunger rod out of the chamber.
Now pull off the two rubber pieces and pop off the plastic disc.
Now you can replace the spring with whatever you want. I decided to go with adding a tek 1 spring, just because Ace #49 springs aren't quite as long and rattle around after each shot. Here's a pic with a #49 spring on.
Now put the disc, plunger head, and plunger stop back on. Take the plugner head and invert it for a couple seconds. This makes the plunger head flare out wider, creating a better seal. Lube the plunger chamber up afterwards.
Now it's time to rebarrel. I used 4" of 17/32" brass with 1" of 1/2" brass nested in it. Put some etape around it so they fits snugly in the original barrels.
Don't forget to plug this hole on the bottom barrel.
Now glue the two barrels onto the barrel selector
Close her up and it's done!
Ranges are a decent, the two I measure got 44' and 46', and the others fell close to 45'. With bungee's/bands you could probably squeeze 50' out of it. The great thing is it's dead accurate! Within 30' I should be able to hit anything (unless the opponent is like one of my friends who can dodge anything and/or have a probability flux around him).
