The first step in this custom 500 build is to install a Magpul forend. Now, they no longer advertise this as being 500 compatible, but I'll show you how to tell if it'll work for your gun, and how you can keep your heatshield!
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...
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
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
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.
Just crimp it bro. Likely too late, this comment was a year ago, but the crimp works great. Vise crimp with a pad to stop marks and rubber mallet the rest evenly. Good luck.
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).
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 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!
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....🙄
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!
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.
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.
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.
ANTI HERO Of course the magpul one. If you do the mossy fore grip let us know how it turns out. Might want to practice on it before you start on the magpul grip. I practiced on some BB gun parts first. The materials vary in composition so start in a spot that isn't seen till you get your heat/technique dialed in.
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?
You sir are a genius.... Please verify a year later. Are you still good? The forens still rigid and holding up? Bending the heat shield defeats the purpose of a heat shield.😊
@@Paco-hh4jd You the man! I got a 590A1 and you have given me confidence to hear and bend the forend. I was gonna Dremel. But your idea is significantly smarter and easier.
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
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
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
From what I've seen online, M500 parts are far enough off that they won't fit without substantial modification. Looks like there's not a lot of aftermarket support for it right now, unfortunately.
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)
It's infinitely easier to bend the heatshield than to evenly sand/dremel down the inner edge of the heat shield. Sanding plastic like this with a dremel tool is a recipe for wavy bumps.
@@nypigskin No it doesn't, it has raised dimples that continue to stop the heatshield from fully touching the barrel, retains an air gap and stops the shield getting hot. Having done this mod I am 100% sure the heatshield retains it ability to protect the shooter from the hot barrel. As standard the heatshield is very far away from the barrel at the sides and is what I would describe as a poor fit.
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
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.
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.
Yeah, the Magpul forend isn't compatible with the factory Shockwave from what I've seen. This video is only for the standard 500/590 guns. Ultimately, I turned this into a Shockwave build using the kit that came out before Mossberg started selling them as factory guns, and retains the Magpul compatibility.
The Magpul website apparently advises that their 500/590 forend does not fit the Shockwave 590, but the Optics Planet web page (including the reviews) did not mention this important fact. I just left a review to let other Shockwave owners know. I guess I should have done my RU-vid research before getting cut on the new Shockwave bleeding edge. The corn cob forend went back on my Shockwave. I guess I'll use the Magpul forend on my pistol grip 500.
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?
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.
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?
Mr Anachronism ~ This is what I did. I ordered the action slides from the Mossberg 500. Then I ordered the Magpul for hand grip I wanted. And installed. Good to go other than excessive amounts of money in to some thing such as the Maverick. I’m happy. I believe that’s all that matters. Thanks again for chiming in
What sucks is the amount of video’s that exist in regards to the Maverick and changing the forehand grip. Let me simplify it for those that are confused as I was. First. Check to see if the Action Tube Rails on your Maverick are Built/Molded Into your current ForeHand Grip. ***If The Action Rails ARE built into your Forehand Grip, you’ll need Two Items. 1.) Mossburg 500 Action Tube Rails in 7 3/4 2.) ForeHand Grip of your Choice. It’s that simple. I hope somebody makes a video that is more streamlined and easier for people to understand regarding this specific weapon. Obviously there’s a different generations of the Maverick and or different configurations due to existing parts within the factory. So identifying what you have is the very first step. I’m happy to help since I have now completed it if anyone is unsure or still confused.
Yep, I just did mine. I didnt crimp my heatshield, though. Well, technically i dont have an A1, i have the plastic trigger guard, but it is the 20" Heavy-walled, bayonet accepting 590.
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?
+Tom Dietzman the measurement is for the action tube inside your plastic hand guard. Gotta unscrew the front, slide the plastic cover off and measure the metal inner tube. If your plastic cover is pinned in place, you need a new action tube to fit this.
