Mossberg 590 w/Ghost Ring + Heat Shield. Explain Incompatibility.

stagolee · November 27, 2004, 05:04 PM

Hey, I have a Mossberg Persuader 590 w/Ghost Ring sights. Mossberg plainly states that their heat shield will not mount on the Ghost Ring models.

To my naked eye, I can't see why I can't have the heat shield on my shotgun. The line of sight is not obstructed, the movement of the pump does not appear to be obstructed. I've never gotten a good, clear answer from Mossberg or the various merchants I've asked.

The best answer that I've been able to deduce is that maybe it's related to cumbersome installation/removal process and the risk of trapping moisture under the hardware. I don't know for sure... this is simply my best guess.

So, I'm turning to you folks.

Why can't I mount Mossberg's heat shield on my Mossberg 590 Ghost Ring model shotgun?

Best guess is, the heat shield won't fit over the front sight during installation.

Some heat shields are riveted or welded together at the front end, and the hole isn't big enough to slip over the taller front sight.

I have a heat shield model and you're right, it looks like it would fit. The problem is that the heat shield goes on over the business end of the barrel, so you can't put the darned thing on with the taller GR sights. You can pull the barrel and try to put it on from the receiver end, but the barrel tapers and the heat shield tapers with it so the receiver end of the barrel is too large as well.

You should be able to design or make a heat shield that will work, but the stock mossberg part won't. No promises with generics either.

I have the standard thickness barrel, and the heat shield is a pretty tight fit between the magazine tube and the barrel. I don't think there is enough clearance for the heavy barrel 590A1s to mount them either.

It looks like the two of you have solved that mystery.

I'll look for a third-party heat shield. Or, perhaps, concoct a modification to the forward mounting bracket on the Mossberg shield.

Thanks.

Or you could just skip the heatshield all together?

I have taken two shotgun classes from Louis Awerbuck and never once saw the need for a heatshield.

I like the way it looks. Nothing more. Nothing less.

I know what you mean.

Then again my serious shotguns are very plain jane.

I use 18" 870's without a mag extender. I think the 870 with the standard mag tube feels just about perfect. With the extra rounds I feel like the shotgun gets muzzle heavy and does not handle as well.

A tac star universal on my 590.

Thanks for the pics. I'll look into the TacStar universal heat shield.
