Hello, I've got a 1950's wingmaster that I'm trying to get the mag spring retainer out of. I want to take the the block out of the mag. I can't seem to figure out how to do this. Does the retainer at the end of the mag unscrew or do I have to drift it out? It looks like a split insert that should compress. I don't want to bugger it up so any info would be appreciated. Thanks Pete
