We provide an in depth, side by side comparison of the triggered Harbor Freight blast cabinet gun that comes standard with the Harbor Freight Blast Cabinet and the higher quality, and more efficient, trigger-less blast gun sold by Best Tool Upgrades (www.partswasherupgradekit.com). See for yourself, based on full cutaways of both guns. Now you will understand one of the primary reasons that your HF blast cabinet provides only mediocre performance straight out of the box and why our upgrades can so vastly improve efficiency and functionality.
