I'm new here but I have a problem to solve with myBLR .243 1976 BLR bought used and fired about 25 rounds. Mag was easy to load and unload until suddenly it was hard to insert into the receiver then would not release. I finally forced the release enough to remove the mag. The latch is stiff to move either direction and acts like it has no spring. Anybody ever have anything like this? What is the fix? Thanks.
