Boomstick

Overview
The "Boomstick" is the nickname given to a improvised, sawed off double barrel shotgun. The weapon itself resembles your ordinary sawed off, but has the end of a hockey stick attached to the back of the wooden handle, acting as a stock. It also appears to have been slightly modified on the barrel, as two rows of metallic plating can be seen, most likely holding them in place.

It fires 12-gauge shells.

Official Description
 "Improvised double-barrelled shotgun. Powerful at short range."

[Note: too lazy to script scattering projectiles, just pretend it shoots pellets.]

Trivia

 * The name of the shotgun is a reference to the movie Army Of Darkness, in which the protagonist wields a sawed off shotgun and refers to it as a "boomstick."
