Need a little help and advice folks. I recently purchased a McMillan MC3 stock to fit a Remington 700 BDL bottom floor plate magazine and when I tighten the screws down, I can't lift the bolt. I have checked everything I can think of to see what is binding it. The only thing that I can see is it might be pushing the magazine liner up but, can't find a mark on anything, anywhere. If you have had a similar experience and can advise me on how to correct it, I would greatly appreciate it.
