magazine cutoff help

[west2509]

I need help. the original magazine cutoff broke. The one that I had been using now wont stay in place or it goes into far and wont adjust. What am I doing wrong?Yes I amusing spring but it doesn't hinge.

What model of gun we're talking about here?

oops it is a 99f in 308 below the one million serial number. The original broke (my fault)I replaced it with one from gun parts corp, but maybe I polished it to much. Or the spring is weak any help would be appreciated.

My 99 knowledge isn't the greatest so you'll have to wait for someone else to chime in on this one.
