For the spring I used two Ace Hardware #155's. I stretched one and trimmed the other until the gun cocked properly. The PVC barrel fit inside the original barrel perfectly, since it was sized for Megas. A little epoxy and the deed was done.
Cocking is achieved by 550 cord and a keyring.
Range: Goes to the apex of a two story house, straight up. Much longer range than a stock longshot or vulcan. No other measurements made.
