Crosman Quick tip to remove the gauge block from a Crosman Benjamin pistol

I use a piece of coat hanger with a right angle bend, but I also have a special rubber piece sold by Archer Airguns that fits in the gauge hole, preventing the o rings from being cut.

As long as your gauge block/tube/oring fit is PERFECT, the zip tie technique is great, but if not, better have some spare o rings!
