I have a Mossberg 590 with ghost ring sights. Mossberg says that their own heat shield will not fit on shotguns with ghost ring sights. So my question, is there a matte/parkerized heat shield out there that will fit my gun?

The answer is no, but if you are handy with metal shears you can cut one to fit your gun, then bend and rebend it to go over the barrel. But why? Heat shields came into existence for WWI trench shotguns and were to protect the off hand when using the bayonet, the presumption being that one is using the bayonet because he is out of ammo and thus the barrel will be hot. If you plan on sish ka bobbing your offenders after shooting them, then maybe the heat shield will be useful. Other than that scenario a heat shield is pretty much useless, and falls into the catagory of "tacticool" devices for wannabes.

I guess I don't wannbe be like you.
I have heat shield on my shotgun and find it useful at times of sustained fire and reloads. Also I am hard on my working shotguns and the shield protects the barrel.
NWdude83 The Mossberg heat shield can easily fit your shotgun with GRS.
There isn't any problem with getting the shield over the barrel. You will have to remove the barrel to install it though. Once the barrel is off, you will have to start the shield on by slipping the rear ring of the shield over the barrel just after the front sight and sliding it rearward, then slipping the front cross screw ears over the barrel just after the front sight.
If it is a 590A1 with a heavy barrel:
You will need to relieve some of the metal inside the shield on the underside of the front band that contacts the top of the barrel. You will also have to slightly open up the cross screw holes, and get longer cross screws. There is a lot of trial and error in fitting the thing, and just make sure you don't take too much metal off.

Thanks Max100, I just believe that a heat shield will make it a little more convient/easy to pick up my shotgun after shooting it, and laying it down or standing it up at the range. And no, its the 20" barrel model.

The John Masen HS is good for the money and looks nice. The clamps are made of fiberglass also with brass threaded inserts. Don't over tighten the screws or you will damage it. It won't heat up like metal but it's not as durable. I have one and like it.

Will installing a heat shield scratch the finish on my shotgun? I'm not sure if I want that Mossberg one or the John Masen. How well are those ATI heat shields? Also there was some other brand out there but I can't remember the name.

You can tape the barrel where you slide it on then remove it. The ATI not so good. The Mossberg heat shields are the best for durability.

one thing to be careful about, though not a problem on the 6 shot 500 and probably not the 590, is the heat shield jumping forward. I had an eight shot about fifteen years ago that came with a heatshield, and in the first mag, the shield jumped forward under recoil and the rear tabs interfered with the pump handle, not allowing the thing to cycle all the way. I promptly took it off, though it looked tacticool (not a word back then). On the 6 shot the barrel attachment lug keeps it from shifting forward. On the 590 the bayonet lug looks to keep it from moving forward too far, but there is a bit of a gap, you might want to try sliding it against the bayo lug and see if that messes up the pump stroke. The newer heat shields comes with a spacer that goes between the heatshield clamp and the barrel lug for the 8 shot models.
The issue with the heat shields on 590s moving forward is due to the plastic standoff that is to be attached to the front of the heat shield using the bolts that clamp the front part down to the barrel. The plastic insert extends to either the bayonet lug support attached to the barrel for parkerized models or to the magazine support also attached to the barrel for the Mariner model (which does not have a bayonet lug). This standoff will prevent the heat shield from moving forward under recoil. Without it the shield will move no matter how tight you crank down on the bolts attaching the shield. (My 590 Mariner came with the wrong shorter standoff for the parkerized models. Thought I could bolt it down tight enough to keep it from moviing but it moved about 1" forward after a couple rounds. Made my own correct length standoff out of maple.)
One option (one I've done with a parkerized model) if you prefer the ghost ring is to get a regular bead sighted 590, attache the heat shield, and attach an aftermarket ghost ring system like that from MMC. The front bead is replaced with a blade on a band clamped onto the barrel end.

I put and ATI shield on my 870 HD model, kinda cheap but it gets the job done. The instructions say to put a patch of cloth under the shield in certain spots to prevent wear.
One option is to just get a heat shield with ghost ring sights on it. ATI makes one for about $30 I think.

Here is a Masen heat shield on a H&R Pardner Protector Breacher Demo shotgun. The Breacher brake was made and installed by King Armory.
Here is a Masden HS on a NEW 18.5" 870 with one of my 7+1 tube ext.

I do a lot of trap shooting, and I can honestly say even after 50 shots shooting doubles in the summer, the barrel isn't going to burn my hand. I can't honestly imagine a situation where you would be shooting enough rounds to make a barrel scorching hot.

Max100, on Midway's website someone recommends buying some 4-40 1/2" screws for the JM heat shield. Which screw would you recommend? I see there are button head and socket head screws, and there might be others that I'm not aware of.
MAX100

The button head screws would probably work better because they will be lower profile. You will have to be careful to over tighten and crack the HS. You can get more torque on the socket type screws.

When I was farming, I used to shoot blackbirds in the sunflowers fields and buy shells by the case when the reloading press couldn't keep up. You stuff shells in as fast as you can and blast them off into the flock with the hopes of crippling as many of them as you can (reason being that the call of an injured blackbird in distress tends to keep the rest of them away) and when you fire at that rate, the barrel can get pretty warm. My last blackbird gun was a Norinco trench gun and the heat shield did a great job of keeping the hot barrel away from any exposed skin.

I knew I forgot one, flat head screws.
NWdude83

So flat head would probably be better than button head right?
MAX100

There is nothing wrong with the screws that comes with it. I would say button head, if you want to replace them. If this is going on a 590 I would get a Mossberg heat shield.
