Very well made - one major design flaw - FAB Defense AR15/M4 Collapsible Buttstock for Mossberg 500 w/ Shock Absorber Option

I got the folding, shock absorber version. I really wanted this to be my new 590A1 stock. It is VERY well made. The folding system is robust, and clicks firmly into the folded and unfolded positions. The shock absorber is firm enough to properly shoulder and sight in without being "bouncy", and offers enough spring to genuinely soften recoil. The graduated length positions click and hold firmly into place.

The major design flaw is that in the folded position, the stock blocks the QD swivel socket on the left side of the stock. Thats the position I would click a QD sling swivel into for my preferred sling set-up. This makes it so I would not be able to fold the stock if I desired a shorter length on the fly. Also worth mentioning... none of the QD sling swivel sockets have detents, allowing the QD swivel connectors to spin freely which could lead to twisted slings.

Take a good look at the other Fab Defense shotty stocks to see if there's one that suits you. Truly world-class fabrication.

I'm sad this one didn't work out. I am considering the non-folding version w/ the shock absorber, because these stocks are so well made.
