First, the NF. All this is pretty standard, so I won't spend too much time on it; lose the restrictors and the barrel, and glue a 1/2" CPVC coupler onto the stub that used to plug into the barrel. I dremmeled my coupler slightly, so it seats over this stub for a more secure fit. Improve the seal, and rip out that useless light; this turret will not fit without minimization. Cut the shell just behind the swelling that used to house the light. Essentially, you want to take the top blaster, and turn it into the bottom blaster:
Now that the gun is ready, we can move onto the interesting bit: the turret. Take 6 3" cpvc barrels, and glue them evenly around a 1/2" sched. 40 pvc coupler (the coupler could be replaced with an equivalent length of 3/4" pvc). Make sure that the right amount of barrel protrudes beyond the lip of the coupler; you want it to fully engage with the coupler on the front of the blaster, but not get stuck. The left side will engage with the blaster.
Dremel a bit of 1/2" pvc out until you can glue a 4" piece of cpvc in (conversely, you could simply use a cpvc coupler). Mount this under the coupler on the blaster. I wrapped mine in e-tape to cut down on rattling.
Dremel a small ring of pvc out until it can barely fit over the 4" cpvc rod. You should have to tap it on. This will retain the turret. Slide the turret over the rod.
Almost done. Tap the pvc ring over the tip of the guide rod, and you're all set.
To advance the turret, just pop it out of the coupler, rotate, and pop the new barrel right back in. This turret gives a good ROF, without losing air. Plus, it's cheap as hell. Questions? Comments? Hurtful Sarcasm?
