About Spud Guns

Fully Assembled Breech Loading Sureshot BL-520 Spud Gun with Interchangeble Barrel System

Our best seller, fully assembled and shipped to your door, just add a 1lb bottle of Propane/MAPP gas and (2) 9volt batteries (one for igniter and one for mix fan) and you're ready to send spuds into orbit! With the interchangeable barrel system, you can swap out to a Golf ball barrel in seconds.

Our ultimatespudgun.com test engineers shot our BL-520 through a Chrony® and the results were staggering. After setting up our third test round (100gram potato) we acheived a whopping 517 fps & 915 ft/lbs of energy using MAPP gas (MAPP gas has a 26% faster flame velocity than propane). The breech loading system proved to be a breeze, simply unscrew the rear cap, shove potato in the rear of barrel and replace the cap. We ran the vent/mix fan for the duration of our testing, used 2 metered injections of gas set at 39psi and paused for 5 seconds before firing to allow for adequate air/fuel mixing.
