I usually find these at Wal-mart or Meijer for $15 (way overpriced), but after seeing them on sale for $10 once, I figured why not give it a try.
I took out all the screws, including two that hold the front piece on. Also use a tiny flat screwdriver to remove the clear canopy on the back; there are tabs holding it in place.
Here we have the inside, plunger, electronics, and all. Lets measure, and then remove.
There's about 3" of plunger draw on the thing. pulling the trigger moves the large white plastic rod, which in turn a) presses the sound effects button and
pulls on the catch. Also note the somewhat unique catch:
Now with the plunger tube out, let's look. the cap on the back just takes a turn, and it comes off. Two little plastic guide tabs are what hold it in place.
Plunger head is normal, although the o-ring is a clearish rubber. No real difference. The thing is well-lubed, and actually has a 100% seal. Nice surprise.
I would replace a spring, but I don't have any that fit. You need about 3" long, with an OD less than 27/32", in case you want to try.
I simply cut the front off the tube, expanded the airhole, and dremeled a bit around the base of the ammo holder, as it was basically the same OD as 1/2" CPVC. Slapped a coupler in there, carved the insides a bit, and put back together. Well, almost. The first try failed, and I had to cut out more plastic.
The final product, with a 3" CPVC barrel:
Ranges: stock, the darts went 20 feet, if that. Modded, both stock and slug darts do 40', and my single bb stefans do 50' consistently. A bit overpriced, but a decent sidearm, with sounds to boot.
Final note: the handle is tiny. Not entirely unconfortable, but if you have big hands, this blaster is not for you.
