I have a veteran 25 cal and one of the magazines doesnt work The pellet probe hangs up onthe rubber o rings when being pushed foward and I have to lift the o ring a bit to get the pellet loaded. It looks like he trough that the o ring sits in was milled too deep and the o ring sit down into the pellet holders too far. anyone seen this? I am gong to try a fatter o ring that might let the pellet proble slip by. Any suggestion?
