My mossberg 500 does have the 4 set screws, and they line up perfectly with the holes on the rail. However, the holes are too small for the new screws

Our rail is made for post 1997 Mossbergs, as described in the description.If you have a pre 1997 Mossberg, the holes are shallower in size and require a different threading pattern. The rail will work with different screws. You will need 6x48 TPI screws which you can find in a hardware store.

Anyone know what size screws this uses? Ordered UTG model & came with 8 x 40, Mossberg 500A is tapped for 6 x 48, screws were too big.

You have the same problem I'm having. You have a pre-1997 model tapped for the 6×48 screws. All these mounts are sent out with 8x40 screws for post-1997 models. I'm searching for screws to work. Maybe one of these companies will have them. Good luck.

would this fit a mossberg blaze 22lr

No it wont, only made for the 500 series shotgun.

Will this fit a 1997 Mossberg 500A?

I have a pre-1997 500A, and there are "no" threaded mounts anywhere on top of the receiver. So, unless this rail uses one or more of the threaded side mount points--I don't see how it possibly can be compatible with the 500A.

Great Rail and Would Buy Again

Very well made and tough rail. Fits perfectly on Mossberg 500 and only took minutes to install. It came with 5 screws and a wrench which thankfully fits my red dot. You can still aim down the rail without your aiming device attached. However, your field of view is slightly limited left and right. But, it acts like a rear v-sight so it balances out. I did use lock tite for insurance. I am glad I purchased this rail and I would absolutely buy another one.

Screws

This is a solid product and fit perfectly on my Mossberg 500. However the provided screws were way too short. Had to lookup proper screws. You can order them or find at ACE Hardware. And, they aren’t cheap.

If you're looking for a good picatinny rail.

This picatinny rail does the job. It hasn't slipped or came loose in any way possible. IT holds my Green Dot perfectly.
