Mossberg 500, what did i do wrong?

[psdan000]

ok so i installed one of those weaver scope mounts onto my mossberg 500, one of the side mount deals. i have no idea what i did but now the gun will not feed any shells onto the elevator from the magazine tube. i removed the barrel, removed the trigger housing pin, ejector and ejector screw, installed the new hardware given in the kit and put it back together. i cant even see how any of those things would even affect the gun being able to load shells. any help is appreciated. thanks

Heard or read somewhere about a similar problem with a 870.
Problem was the trigger group is normally held in by two "pins" and the mount uses a bolt/nut to hold the mount on. With the pins the trigger group "floats"
(for a better word) in the receiver, with the bolt/nut setup it applies to much side pressure to the receiver wall causing the trigger group to screwup?
I believe the answer was to not over tighten bolt/nut and give the trigger lots of room to move around?

* the old trigger group controls about all the feed/lockup and everything else with a pump or even a autoloader for that matter.

well i tried loosening the screw, even took the whole trigger assembly out and put it back in, made sure there was plenty of play in the trigger assembly. still no go:confused:

I bound my 11-87 up with a side saddle before. The screws were to tight and pinched the reciever.

Check your gun, it should have a set of taps on the top for a rail/bases. If it does get rid of the thing and buy a reciever rail or scope bases.

so if the reciever is damaged can it be fixed? why would they make a product like this if its that easy to damage the gun?

[psdan000]

ok well i found the problem, i feel pretty stupid now though, but i cant say its entirely my fault. the scope mount mounted on the side does not allow the forearm "pump grip" to come back all the way. so now i need to grind the mount down to allow it to work, talk about a bad design:barf:. i guess it may work fine with other 500's without a wood grip? i dont know, just thought id share the info to everyone else.

that was pretty silly

I had the pump on my 870 sawed off short to accommodate a side saddle. I had to argue with the gunsmith to get him to do it. He was an older guy and couldn't figure out why I needed that confounded contraption bolted on the side of my gun. Heh, I respected his opinion but it was my gun after all.

I've since taken the side saddle off my 870, but I really don't care about the pump grip. Actually, I think it looks better with that bloated part sawed off and I don't plan on ever selling ole "Elmer" so I don't care about resale value. FYI, they sell after market pump grips that are shorter to allow for stuff like that.

The reciever should be fine. I loosened the screws and my 11-87 worked fine.

An after market fore end that doesn't overlap the receiver should fix that problem, and you won't get clothing or straps wedged in there.

And the Mossy uses an aluminum reciever, which is susceptible to over-tightening problems with aftermarket goodies.

The synthetic "corn-cob" forends do not overlap the reciever at all while the wood fore-ends do..just a tad.

Your 500 isn't a Bantam model, is it? On those, the forends overlap the receiver by quite a bit, because they're rear-mounted to be easier to reach for short-armed shooters. As mentioned, the shorter corn-cob style is the way to go. Try Numrich (http://www.e-gunparts.com/productschem.asp?chrMasterModel=0840z500) or Havlin's (http://www.havlinsales.com/).
