We were just playing around and I screwed a paralyzer tip on, this gun was perfect.  Very surprised at the price.

Nailed this guy on the wreck of the Proteus of the outter banks in NC.

With the HammerHead railgun its rapid fire single band load and shoot no need to wrap.  Its perfect knowing I can get a HammerHead then upgrade the parts that I want.  I am gonna get an open muzzle next.
