PBLK-415
Premium offset coaxial DIY package from the ultimatespudgun.com.
This kit includes the necessary Sureshot components to build our featured BL-415.
Our ultimatespudgun.com test engineers shot our DIY BL-415 through a Chrony® and the results were impressive. After setting up our tenth test round (80 gram potato) we acheived 374fps & 383ft/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 1 metered injection of gas set at 37psi and paused for 5 seconds before firing to allow for adequate air/fuel mixing.
