After cleaning one that wasn't working that well and moving the spring one hole over I had to take apart my other mags and move the spring over, it really made the rifle cycle better.One thing I don't like about the magazine is that some pellets are very noisy in the magazine and if you are carrying more than 1 loaded mag (say one in a pocket) the rattle can be louder than walking.
I have one with a stripped screw, any suggestions?? Scrap it??
