Hatsan Air fill probe mod?

[Arkansas_Airgunner]

They fall out becasue the probe orings get wrecked going in...iv had to keep replacing them because they get peeled when goin into the port...they are factory orings for my Hatsan NeutronStar..

A little silicone lube on them helps keep them "poofed up" plus the probe will slide in/out easier without trashing the o rings.

FYI.. A little tip I picked up recently.
For those of you who like to leave the probe in the gun as I do, a common tire valve cap fit on the foster fill end of a probe. It kinda snaps on to keep dust and debris out. There are dust caps available online but these are cheap in a pinch. Most of us have a few laying around our shops.
For those of you that like a little more spice in your life... try a 9mm shell casing with a small magnet glued in it.
