Ok I am no expert but i have a friend who did that. what he did was drill out the front but not too far down only really to open it up to the point were he could fit cpvc in to the hole. Then he hot glued the cpvc to the front of the gun.
it gets great range but i don't know if he did anything else to it. So yeah
No, it is not is not accurate. With the two darts in the barrle it is a hit or miss game. When you fire it you are holding it with only one hand and the kick of the plunger totally throws your aim off. I don't know if it is the rerelease because I got it as a gift when I was like 6.
