You completely demystified the process. Best instructional I think I've ever seen. One thing I did differently was using a leather/silver workers rawhide mallet to peen over the heat shield. It was fast and really curled over the shield to hug the barrel. Weird I had a leather hammer but not a mousepad...

Well done. All vids I have seen have you break down the entire action.

wow thanks for the video, been wanting to do this but thought it was gonna be a lot more technical, I have the same shotgun and definitely wanna keep my heat shield

Easy to follow, straight and to the point. Thanks man

Thanks for close-ups of work and plain background with good lighting. Very good DIY video.

cheers to you sir. Easy, straight forward and helped me install my new forend in a matter of minutes. My first shot will be to you Booligan!!

Saved my Christmas gift. Thanks man!

I think the Anti-Rotation insert went in BACKWARDS! It says flat end towards the forend! Thanks for the heat shield tip!! Worked grea

I just did this to my Mossberg 500 SPX. Mossberg says you cant put a heat shield on that model due to the tall sight on the barrel - but spreading the front of shield apart a little did the trick. Also - my heat shield isnt contoured like that one. It comes down much further around the sides. I left the heat shield on the barrel and covered the teeth on my vice with a cloth, and used the vice to crimp it down. Finished it off with a soft face hammer from Harbor Freight and the Magpul grip slides easily back and forth, just barely touching the shield when the gun is racked all the way back. The SPX model comes from the factory with a pistol grip, ported barrel, ghost ring rear and AR style front sight. Shotgun looks awesome now with FDE Magpul furniture and factory parkerized heat shield. Just added the QD cups in the stock, and a QD front magazine tube cap for a Magpul sling. 7 round Black Velcro mounted elastic side saddle from Esstac on the receiver. Waiting on an Mlok mounted front hand strap made for the Remington tac14 which uses the same Magpul grip, and the 400 lumen Inforce light also in FDE to finish it off. I like “this” shotgun better without the factory pistol grip and kinda flimsy AR style stock it came with. The Magpul stock is much better. I have a shockwave that i converted over to a pistol grip and arm brace anyway, so its nice having this SPX with a more traditional style stock setup. Don’t wanna sound arrogant, but i gotta say my SPX is pretty friggin sexy looking now. This vid inspired the transformation. Thanks

Thanks. I appreciate your attention to the graphics. Without graphics, these kinds of presentation just do not work. And taking photos of a nonm-reflective black surface is a tedious job. You did well. Thanks. I plan to make the same modification, but I shall take some time sanding down the inside surfaces of the Magpul fore-end, to gain a few extra thousandths of clearance.

Thanks for the great video man. I am about to install the same forend on my 890 Shockwave (thinking about making a video, I'll try to remember to give you a shoutout if so).

Dang I ain't seen one of those bracelets since the early 90s. Great video

awsome pieces and love the bracelet

Good tip on the vise. Good man.

Nice little mod. Thanks for the tip.

Very good video, helped me out alot, cost me $0, fixed the problem I was having! 5/5 stars!

Great video, even better 90s friendship bracelet bruh

Looks awesome with that magpul forend. I hate that corn on the cob handguard. I got a nice hogue one but couldn't install it cuz my maverick has the action slide tube attached to the forend

I swear to God.... I had this exact problem about 3 hrs ago..... didn't look anything up, just switched the heat shield to another 500, and now this pops up in my feed ?!?!?! BIG BROTHER IS OUT THERE....🙄

thanks for the video lg from Germany

Great vid! I have a very old Mossberg 500 AB that was given to me by my dad and it has NEVER been cleaned. When I removed the forend nut, I see a little ring that appears to be stuck on the tube not allowing me to take off the forend. Is it really stuck or should I use a rubber mallet to remove it? Any advice? Thx!

I have found what I believe to be a better way. It involves time and effort, and a little known practice of fitting parts. I (successfully) tested the proof of concept (poorly) with a black one, then found an FDE one online to match my SGA stock. For specificity I have a Mossberg 590, 20" Accu-choked Heavy Walled Barrel, w/bayo lug, Model #51663* -Take the Magpul pump, lay an MLok rail in the slots on the side. -Scribe a line on pump where the top of the rail meets it. Do that on both sides so that both sides have a scribed line a few mm from the top about half of the length of the pump. -Now flip the pump over and run it over 80 grip paper while applying even pressure. -When you get half a mm above that line, stop. -Flip it back over, clean it with progressively finer paper (200-400-600-1000) to get rid of the marks and round off the edges. -Now you have a fitted pump that can still accept MLok rails for stuffsnthings and fits with the heatshield that is still doing its job by being far enough away from the barrel to resist heat transfer. *That's the closest model to what I have. I have a heavy walled barrel and bayo-lug like a 590A1, but I also have a plastic trigger guard like a 590, BUT also an accu-choke brrl which is only listed on one 590 option and no a1 options. My model no longer appears on the website because I guess we can't have nice things. The perfect pump action offered up by a company with sub-par options.

Great Video..Thank You

Its funny how both Magpul's website and on the box say only for the 590/590A1. However, the instructions inside the box point out which of the two spacers to use for the 500 series. I fitted one recently to an ATP8 500 riot gun from the 1980s - and it fits and works perfectly.

very well done. thankyou

Thanks for the info man 🫡

I never would have thought about crimping the heatshield

Nice. Plan to do this to my persuader 500a. It should fit right?

Did you find that it eventually wore off the coating on the heatshield? Mine did in a few places and I was surprised that happened.

These are great forend hand grips I installed one on my shotgun fix the problem of my sleeve getting jammed in the forend grip while pheasant hunting could not get off a second shot now I can

Great review and I was able to retain my heatshield by crimping slightly in the vise. Perfect fit and function.

Stipple the recessed area of the foregrip. You'll wonder why it doesn't come that way from the factory!! Man is it ever grippy and looks awesome!!

Great video, helps alot before making the forend purchase. Not sure if you would be able to answer or have some insite. Looking to add an aimtech warhammer in replacement of the heatshield. Wondering if it would even be worth trying to see if the M-lok forend would be compatible. Would look sweet if they were. Thanks!

So, does the magpul forend work with the shorter 6-5/8ths inch action tubes? I have the shorter one, no one seems to answer this question, I'd rather not have to spend an extra 60$ to get the longer one.

With the heat shield it looks like one of those trench shotguns with the regular pump grip

If you have the short slide tube, you can get an extended hogue castle nut to make it work.

Thanks for the info, I would've broken something otherwise lol.

Good info!

Does that castle nut tool come with the foreend or was it a seperate purchase?

Do you have to have forend in certain position to remove barrel?

Could that apply to the 870? And does it block the sights?

Awesome! Thank You...

I had to heat up my Magpul grip with a heat gun and bend it out a bit In order to install the heat shield. Works fine!

Question. Online I see a lot of slide action tubes being advertised as 7-3/4" long. Will those work or does it HAVE to be the 7-5/8"?

Is there any way I can get a Magpul M-LOK forend to be compatible with the RIA Armscor M5?

Huh. Wonder if this will work with the ACM Mossberg...

Very good DIY video. I'm new at this and wonder what level of computer is needed to print out a 3D gun please?

Man ill have to give that a shot with my rem870, putting together a shopping cart for making a duck hunt a home defense and no foregrips seem tk accomodate a heatshield

Glad I saw this before I tore down the whole gun!

Thank you!

Will this fit a maverick 88?

Thanks for the video... I have the Mossberg 500 ATI and I just recently installed the same piece.. I'm not sure if I would have to add 1 of those spacers. I also have to do a little crimping on the heat shield because there is a space and the barrel is not sliding all the way down. Both spacers look very similar. Is there any way to tell the difference or is it just by trial-and-error and do I actually have to use a spacer?

Is that a factory heatshield? Do you think it would fit a 590 shockwave?

I have very noticeable cosmetic issues on my mossberg flex 500 wonder if could just install something else I hate warranty processes

This makes my racking much harder. Trying to find out why. I've sanded my magpul foreend. Not rubbing anywhere. Works fine till I put barrel on???

So I'm trying to to get a tube slide for the mavrick 88 and I got the wrong size I got 63/4 now which one shud I get then anyboby help me? Or tell me where to find it cheap

Will this fit a 590 shockwave with 18.5 barrel?

Couldn't you have just dremeled the inside of the edges on the top of the forend to make it clear the heat shield without bending it? Unfortunately I have the 20 gauge so this forend won't work on mine either way 😞 (although I might try to modify it to fit if I can)

As far as disassembly/cleaning, What is different/same with the existing Moss 590 and new 590"M"?

hey! what heatshield is that? i would like to get the same one been looking all over but this is the only vid i see with the same forend thanks

perfect vid! Let me know if you wanted me to send you some free zytel polymer heatshields to try out.

Does this mean to crimp the heat shield you will need a metal one?

Great video. This is kind of a random question, but you seem to know your shotguns so I'm hoping you (or anybody reading this) might be able to help me out. I have a rock island armory M5 12 gauge pump (nickel), and absolutely nobody makes any aftermarket furniture for it. Do you have any idea if this would fit my gun? I wouldn't mind doing small modifications to fit if needed. My understanding is my "M5 shotgun" is basically a clone of the "high standard flight-king". I have also heard mossberg come under fire back in the day for basically coping the flight-king to design the model 500. Since both these guns took their inspiration from the same shotgun, I'm hoping they are similar enough that I can steal from the massive pool of aftermarket 500 parts to fit my R.I.A M5. Any help would be appreciated, thanks

QUESTION: When you did the Mouse Pad + Vise number on the heat shield, did you remove the heat shield from the barrel, or leave it on ?

i used a castle wrench for an ar to take the nut off. i didnt have a wrench that came with mine.

How difficult was it to bang the forend off ? Thank you great video

The legs on my forend will not detach, i think i will have to purchase a slide action assembly to attach magpul forearm, u have a different model 500 than i do

I'm needing a forend for my Mossberg Shockwave.

Thanks for the video. On the 590 Shockwave, the new forend does not slide on easily as shown at 5:30. I"m off to watch a Shockwave Magpul forend video.

So no to my molded forend that sits on top of receiver?

Do u have a link for this particular Magpul on Amazon. I have 590A1. Thx

Where did you get the tool for the tip of the forend?

So I have a question if anyone can help. I bought a mossberg 500 scorpion a little over a year ago. I’m wondering if I can also crimp the heat shield and make this work as well.

Hey, I just get a mossberg 500 tactical, it has a heat shield and muzzle brake... the forend is almost 8 inches, would magpul forend fit on my mossberg?

Do you have a video showing how to retain your heat shield. Thanks

Could you just trim the edges of the new forend without crimping the shield?

Would this work on a ria ag 12 gauge? I figure most 12 gauges are similar @Booligan Shooting Sports

Can't see this working with the 590A1 because of the thicker barrel. Thanks for the informative vid though.

i have the forend grip with the pin in it can i still use that grip

Can u add a pistol grip to the new forend?

You can put anything on the short action tube. There is an extension nut you can get for like 15-20 bucks. No need to buy the 7 5/8 slide if you have the shorty.

What’s the overall length?

How can you tell if it will fit on m500 if you don't have original forend?

I'm highly surprised that you failed to use any oil for the retention nut!

Will this forend fit on a 590 20ga?

I recently purchased a Maverick 88. Build date is of this year. My forehand pull Does have a Pin. As I understood you in the video. I CanNot install this Magpul due to Pin in Forehand Grip.. Correct?

OK, I'm confused...the stock hand guard on my 500 Persuader is 8 inches long, and your explanation is kind of confusing. Will this hand guard work only within the 6-3/4 to 7-5/8 range of sizes?

Would this fit a 590M?

Unfortunately, my 500 has the forend that won't allow the Magpul .

Hi, a question.I have a Mossberg 500A .Does this Magpul Forend fit on Mossberg 500A? Thanks.

Are there any forends that you know of for Moss 930 spx ?

What size is your action slide?

Isn’t the point of the heat shield not touching the barrel to help dissipate heat?

Does the forgrip rub at all?

will this work on the 590A1?

Maybe a heat gun and flare the top of the foregrip a little?

Why is it some videos the action slide assembly comes off with forend yours did not? Anyone out there can answer I'm getting my parts soon to install thanks

Mine doesnt fit to my mossberg 590’with factory heatshield.. but when looking at your video yours is also a factory heat shielf

Does anyone know if this could work on a maverick?

No sanding? Heatshield
