Am i doing something wrong with my 500?

[GrimLock]

Picked it up today from Big 5 and was excited. So I put my choate forend onto the 500 and when I rack it forward. It slides forward and doesn't stay in place.

I don't know whether this is normal or if I got the wrong forend. I looked through some other threads regarding forends for 500's. They all talk about buying new lug nuts, etc.Then apparently there are choate forends that fit the 500 and then another that fits 500a.

Then for some reason I can't load my mossy with out first loading a shell through the port. Now with my 7 shot 870 if I just want to load 5-6 rounds. I can do so and load straight into the magazine.

I did disassemble the 500 yet I put all the parts back in place.

So what's the problem?

[eccvets]

your apparently fked up some place while putting it back together. take it apart and put it back together. have you watched the youtube videos on how to do this? is this your first mossberg?

Yea I must have and I did watch the video on youtube. That is titled Mossberg 500 disassembly and the same guy has a video focusing on the same thing for the 870.

Ill take it apart when morning comes.

I'm really disappointed in the forend because I believed I purchased the right one. Yet it seems that I didn't arggg!

Should have went ahead and purchased the GG&G forend for the 500. Yet I figured for $34 I couldn't go wrong lol.

I planned on having the 870 for the car and the 500 for the house, or vice versa.

Geez

Are you talking about the forend?

The fore-end should wiggle a little in the slots. The two-part fore-end should be tightly together but the slots in the receiver where the action rails go in should be loose. If they aren't loose, then there's your problem, you probably didn't seat them properly. Also, until you do it a few times, lining up the bolt, bolt follower and rails is a major PITA, you may not have properly seated it.

Actually slides back and forth when I rack the the gun, for example when I rack it forward the forend goes all the way forward and when I rack it back. It goes back into place where it should be the whole time. The factory forend stays in place and does not slide forward but this particular forend does slide forward.

I do understand that it says "Mossberg 500 Forend short w/Picatinny" but should it slide all the way forward?

The forearm itself slides forward off the metal piece with the action bars? Or the entire unit slides up? If the first then the forearm is not properly secured. If the latter, then the gun was not put back together right.

Some photos might help others diagnose.

It slides off a bit from the round metal piece containg the action bars. It will actually slide over the lug nut a bit.

Now with the factory forend everything is fine obviously, so I'll take it apart and put the choate forend back on to take pics.

[BigDogatPlay]

If it slides back over the nut, then the hole is too large or there is nothing molded into the forearm for the assembly to lock into.

I've never used that particular unit with my 500, but I've also never had an issue with aftermarket parts on it either. My gun is older so there may be some dimensioning differences on the forearm and action slide. I know they've made changes to it's design over the years.

Pictures:

Slide fully racked forward
1.

Notice how it is damn near completely off the round part containing the action bars

2.

The forend itself slides over the lug nut/retaining ring covering half of it. It is still racked foward.

3.

Rack is still fully forward:

Yet the forend itself will slide back.

3 1/2 .


Notice how the forend now covers the round part containing the action bars. (It is still racked forward and this is a continuation of picture 3)

4.Racked fully back.


Look at the forend.

lol wow that's what I get for going super cheap I guess.

I'll just go ahead and buy the GG&G forend and hopefully it will work.

I've never heard of a "short" fore grip before...that one is definitely too short!
Missing a spacer?

Whew good thing it only cost $31.

I'm tempted to buy the regular length choate forend

I've never heard anyone complain about the Hogue overmoulded grip before. It's possible they sent you the one for the wrong gun. It's definitely not covering everything it needs to. Double-check your order and send it back, tell them they must have sent you the wrong part.
