Does anybody know the correct head type and size for the bolt handle screw on the Umarex Gauntlet? I had an O-Ring break on it when my kid double loaded pellets into the chamber. I already have the correct sized O-Rings.

Pretty sure it's a 2.5mm , if you mean the small hex in the rear of the bolt handle that retains the cocking handle in the cocking bolt/probe.
