I have just purchased a Mark II TRR-SR 22LR. I have read where sometimes the magazine might cause feeding problems and that a solution would be to add springs. My question is how do you get the magazine apart to add the springs? The sad thing is I first purchased a CZ 455 and was having some trouble with feeding the shells. After trying 3 different magazines I decided to trade for the Savage. Now it appears that I am having the same trouble but not as bad. I thought I would try adding the springs if I could figure out how to take it apart. Thanks.
