Maverick 88 issue

[zky]

Just purchased a HD shotgun - Maverick 88 20" barrel - from GunBuyer. The barrel does not meet up with the mag tube as it should. The barrel is seated properly (and fully) in the chamber. I have 2 other Maverick versions that do not exhibit this issue.

Anybody else every seen this type of issue?




Thank you.

Make sure your slide is open when you seat the barrel.

About the only thing I can suggest is take the barrel from one of your other ones and compare the two. Perhaps that bracket was installed at the factory a hair off?

This. I have multiple 500s. they each have different clearance there. But they all work just fine.

I'm not saying that it would cause any problems, just that it might be the reason. Probably better to have a little gap than too tight.

UPDATE: Well I emailed Mossberg because I've never seen this type of gap before. I sent them pictures and asked their opinion of this fit. Here is Mossberg's response:

Thank you for your email and sending over the photos. Everything you sent over is totally normal and exactly how the fitment should be. Everyone one of our firearms will have the same identical gaps and there is nothing to worry about.

'exactly as it should be'
'every one of our firearms will have the same identical gaps'

Interesting......

Thoughts??

i would just shim it and shoot away as long as the barrel is seated properly!!

if it bothers that bad, take side by side pics of another one you have that doesn't have that issue and ask them if that one that doesn't have the gap, then has an issue?

Would have been different I guess if they said within normal tolerance, etc but that's not what they said.

Maybe that's the one of the differences between the mav 88 and the 500. My dad's old mossberg 500 is tight and no gap.

I had my nephew check his 590 he said no gap.

Then just dremel the lugs at the base of the barrel to make it fit tighter into the action. What could go wrong?

I'd send them pictures of the other two and ask them again. Maybe you got a less than knowledgeable support person. It's happened in the past for me I'm sure others as well.

 

[Cameramonkey]

Does it lock up properly?
Does it fire properly?
Does it eject properly?

If all 3 are correct, based on the CS response, it should be OK.

another thing to consider is that a original barrel or aftermarket one???

I missed that part bought on Gunbroker. So yeah it could be an aftermarket set up.

Not a shotgun guru but I wonder if that space can lead to problems later on it looks like a weak link so to speak. Is that a stress point or not for those shotguns?

Uhhh, where can I buy one of these Dremels? Are they easy to use?

 

[zky]

purchased new
original barrel
haven't fired yet, but will soon

I'm going to shim it so it fits snug and just go with it. I don't care what they say - this gap is not 'normal' or even good. There can't be much load going from the barrel to the mag tube at that point, but it isn't zero - there is at least some inertia load during firing. Having it seated on the end of the mag tube is better than this gap, even if this gap would not create issues for a while. I can imagine the threads having some issues after a significant amount of shooting. I may never shoot it enough to get it there, but it would happen eventually.

Thanks for all the comments and suggestions.

Are the mag tubes the same length off of the receiver?

 

[MrSmitty]

Take a pair of vise grips, or a pipe wrench, and back the mag tube out a little bit to close the gap......Except for the pipe wrench, this might not need to be sarcastic....as an aside, I looked at my Mossberg 500 and it looks like this..,
It shoot fine, and no issues, so OP should be GTG

 

[binkerton]

Damn, now I gotta go look at mine. BRB
Update: Mine has a gap about the thickness of a credit card. Never noticed before, oh well.

 

[LtScott14]

Maybe an Oring or a fiber washer could shim it up? Just thinking. If the mechanicals lock and rock, go shoot it.
