    I think the riser is a good idea if it helps you line up the dot. The only red dot I had on a shotgun was a Tri-Star (Turkish) Semi 12ga with tactical pistol grip stock so the comb may have been different. Conveniently, the red dot co-witnessed with the factory sights. I tend to keep both eyes open when using a red dot, I think? I don't have one mounted right now to check...

    I think i have solved the forward sling attachement and the flashlight attachement.
    I could not solve it as good as i wanted with my limited resources at home,
    so i had to give in a bit on the "not to interfere with the disassembly" rule.
    I can take two extra hex screws...

    I have ordered this monster :) but i will not include the top part
    NcSTAR-MSHBDREM_800x800.jpg
    It will look something like this...
    NcStar-Mossberg-500-Barrel-Mount_2.jpg
    My sling will attached with this on the left side ( which i also have ordered )
    r1.jpg
    And the right side is for a flashlight, when needed...

    Now i have to wait a few days for the stuff to arrive :p

    To solve so many things to such a low cost was perfect. Aprox $30 for everything...

    That's pretty nice for $30. I would agree with Nitesite's comment on the top rail.

    I would shoot it with the cheek riser. Shoot it and try it for quite a while under different situations and loads.

    Jaw weld sucks.

    Weekend work.. again.. :)

    Planned
    • A new and wider cheek rest. More contact with the stock velcro.
    • A QD mount that won't interfere with the cheek rest and the stock bolt.

    Pretty sweet practical use modifications there. I'm used to seeing a lot of folks who just go slapping a bunch of random accessories onto their firearms these days which range from counter-productive to outright detrimental towards one another, like putting a long range telescopic scope on a Shotgun or both a laser, a flashlight, and night sights all on the same gun at once.

    Awesome work!

    My 590a1 started out with a synthetic speed-feed stock. LOP was too long and butt pad cushioning was non-existent. I ended up going with a Magpul SGA stock, but if I had the time and patience, I would've ended up modifying my original stock for better ergonomics like you did with your stock.

    I love the ergonomics of mossberg pump-action's, but the LOP on the factory configuration seems to be set up for gorillas.
