View Full Version : Need info on stock "mounting" bolt for Mossberg 590

Does anyone here know the correct size (number/thread/length, etc.) for the stock bolt used on the Mossberg 590 (8+1) w/ factory equipped Speedfeed buttstock? Im thinking about replacing it with a bolt that does not require using a screwdriver for removal. Thanks.

I don't know the length, thread twist, etc.

Maybe this will help?

If not, maybe take the bolt in to your local hardware store?
