Installed my SGA Magpul stock on my Mossberg 500 stock today and I love it. Got the LOP set just the way I like it, really smooth feeling. However, went to do a field strip and could not get the trigger assembly to pop out freely. I had done some research prior to this stock and it was noted this would happen so I was not concerned. However, in order to get the trigger assembly out, I have to loosen up the bolt on the stock...but I can't figure out how to get the blasted thumb strip off to access the bolt. I've tried a knife, a small Alan wrench, and my fingers...can't get it to pop off. I feel like a complete fool right now. Anyone remove this stock before and can offer some pointers? Thanks!
