I have a Mossberg 500A I purchased sometime before 1990. I don't see any screws or holes anywhere on my receiver. What do I do?

If you don't have any machining/drilling experience or just don't feel comfortable drilling holes into your receiver, buy the rail and take the rail and your gun to a local gunsmith to have the rail mounted professionally. Otherwise, line up the rail DEAD CENTER on top of your receiver approx 5/8" to 3/4" back from the front edge. Gently clamp the rail to the receiver once it's centered and mark the holes with a silver Sharpie. Remove rail and divot the center of your marks with a centerpunch. Get a 4-40 tap and drill bit to match. Slowly and carefully drill all the way through the receiver and tap the holes. THOROUGHLY CLEAN the receiver and remove all bits of metal. Using red Loctite on the screws, mount rail and tighten each screw in small increments until snug. DO NOT OVERTIGHTEN THE SCREWS as you can strip your receiver. Mount your optic and have a blast!!

You would have to take it to a gunsmith to have the holes drilled into the top of the receiver.If memory serves, all Mossbergs after the mid 90's were manufactured with the holes.I'm sure if you take it to a reputable smith and show/ask him what needs to be done, he can drill and tap your receiver in a matter of a half hour or so.

Get your gun tapped for screws by a gunsmith if you're set on mounting a rail. The receiver is aluminum so don't tighten the screws too tight and use blue locktite to keep them from coming loose.

Send it back for a refund, would be my recommendation. I have anther shotgun that came with ghost ring sights and a top picatinny rail so the Mossberg will be relegated to home defense roll only.

Mounting bolts must be grounded good. Clean around bolt holes good to bare metal and reinstall. Good luck

I put one on a Mossberg 590A1. If you look on youtube, they had some video showing different applications.

I never attached the sights because i was missing some of the screws. Despite not using the sight, ive been shooting pretty well. I'm sorry i couldn't be of much help!

Ha Ha, I had to go look. There is two allen head screws holding each one on. Not sure what it looks like without then, but I think I will find out. I'm not a fan of all that either. The AR it's on, I removed the quad rail and put MagPul back on. It's a carbine. Looks better and it's half pound lighter.

Hi Scott, This is Jeff, I'm Colleen's husband. I took my maverick 88 apart, drilled & tapped the receiver. With 8-32 allen heads you will be fine. Just make sure to blow it out good with air gun before re-assembly, & use the red Loctite ! Good luck! Jeff

It depends on how well you separate the slide tube from your molded forend. There is a special tool (search forend wrench) that you need as well because the threads can be damaged pretty easily. My Mossberg was made back in the mid 1990s, and this one fit perfectly.

Ok. Im looking at the Camp 9 receiver and i see the 4 set screws that are in the top of the receiver. it looks like it would fit. the rail i have that i had to modify. there are 6 holes. 2 in the front and 4 in the back. the 2 in the front look uniform and will fit but the question is if two of the back 4 are drilled at the correct measurement. i just measured mine and from the center of the first set screw.(farthest hole toward the muzzle) to the first of the 4 toward the rear of the rail was. 2.5 inches. second hold from the farthest hole was 3 inches. third hole 3 3/38. and last hole was 3 7/8. so these measurements are consecutive. hope this helps. if not sorry.

I can not tell you! I only know that when I ordered my kit(I called Blackhawk) and was told that the stock was what I needed! The installation of the stock was fine,not any problems! However the "forend" would not fit my Mossberg 500 as I was told. The stock works great,I only wish the forend did also!

Flip your gun over and look at the bottom of the receiver in front of the loading/ejection port. If it says mossberg 500 or Mossberg 590 it will fit.

First a question, how does your shotgun eject spent shells? I looked up your gun and could not see a ejection port just wondering. I don't think it will fit your gun as you can see by looking at the picture a screw replaces the pin in the Moseberg and a new screw is needed on the right front the two big holes but you can check with Weaver to see if they make one for your weapon.

I had a Mossberg.. 410 not predrilled. Never tapped before, Screwed it up, Lol, pardon the pun. Should have taken it to a Smith or somebody who knew how to tap. Also, used a hand-held drill. Bad move. Probably done better in vise and drill press

Depending on the fasteners that were holding it on, reattach, widen exisiting holes and bolt it on. Or drill new ones. Just ensure you use good quality bolts, such as a stainless steel. Otherwise, you may need to contact the manufactuer for such a request.

Your receiver needs to be drilled & tapped in a rare thread pattern if it already isn't (8-40?). Front sight will need to be epoxied or brazed on, preferable silver soldered. It's something that should be done by a gunsmith & not an easy project for the weekend warrior. I found out the hard way. Bought all the right tools & it still came out funky. Good luck Doc..Btw, the silver soldering process consists of removing barrels finish around bead, soldering & having to have refinished. $30-50 isn't realistic. It's more like $150-300 to get it done. Vang Comp out of AZ is a trust worthy place to have it done. They are pros who will do it right from start to finish.

If you can't find anything that works, Get a good steel picatinny rail and bring it to your local machine shop and they will make whatever it takes to mount it. Anything can be fabricated. Where there is a will there's a way!

I believe the trigger housing pins (how this mounts the shotgun) are in different locations on the Mossberg 500.

Hello, when I put my pad, on my 500 Mosseberg 12 ga. I tryed, mounting the pad with package screws . Did not work. So I used original screws. Perfect. Now if your pad needs to be fitted to the. Let me know. Good luck.
