Mossberg 500 slide sticking.

[oneshotonekill]

Hey guys, I have a 500 AT that the slide is sticking on. I took it apart and looked at it and gave everything a thin coat of oil and reassembled it and still sticks. What it does is when you pull the slide back aggressively as to make a positive reload it sticks in the rear. You have to put some pretty good pressure on it to slide it back forward. If you do it gently it's fine...????? I tried to research it and can't find anything specific on it. Any help would be appreciated. Thanks

Did you somehow manage to bend your shell stop did you?

If I remember right you can get your shell stop and the bar of the pump wedged and it can make the action stick/stiff/not work

I bought it used and the first time I took it out it acted up like that. I mean every round sticks. It seems smooth but locks back.

What fore-end is on it?
They self center by underside flat of the bbl.
Might need aligned or fitted.

It's all original. I'm wanting to sell it for reasons other than it being sticky. How do I go about getting it fixed?

If you are going to sell it then I'd just let the buyer know ahead of time.

Completely strip the shotgun, see if something is visually off, put it back together, see if it still have the same problem.

If so, let the buyer know

Single bar on the pump or dual bar. Single bar ones are known to bend out a bit causing problems. Might need a new part if it bent and can't be bent back. Once bent back they often re-bend.

have an older 410 camper pistol grip with the single slide bar. Pain in the arse but it belonged to a friend who passed and I just bend it back when it acts up. Maybe I should fix it. Makes a cool early tree rat gun.

Dual bar. I've stripped it and cleaned it.

Dual bar. I've stripped it and cleaned it.

Did you see any places where the parts are interfering with each other????

Should be obvious.
