I install a modification kit that takes the Gauntlet from 60 shots per fill to over 105 shots per fill using the stock 13 cu. inch removable tank. The 37-minute installation video details the complete disassembly of the Gauntlet and step by step installations of the Valve modification, Hammer Spring, Power Adjuster and Trigger spring. I refer to the owners manual and the schematic drawing throughout the process so you will be able to refer to it at any point during the installation.
Here is a Shot string of a stock Gauntlet .22 Caliber with the Super Tune Kit Installed
You can order your Umarex Gauntlet Valve and Hammer Kit from http://www.jsairrifles.com
