HUGE THANKS TO REVIEWER JASON!!!!!!!!!! His trial and error making his 6 3/4 action tube work is nothing short of God's work. His efforts led me to not only have the pump shotgun Ive always wanted AND saved money doing it. Win/Win in my book.

As suggested by another reviewer, you can use this Forend nut adapter to install a 7 5/8's forend on a 6 3/4 action tube. This is significant because there are hardly any forends for 6 3/4. In my case, I was trying to add a vertical grip to my Maverick 88 that already had a Phoenix Technologies Kick-lite pistol grip stock. I wanted a setup for easier manipulation as a home defense shotgun. Since the Maverick's forend has the action bars molded to it, it cannot accept a different forend. Also, finding Mossberg 500 action tubes at the moment is difficult due to this COVIDiocy. When you do find them, the 7 5/8's is nearly $80! A new 6 3/4" is about $50. If I can save $30 Imma do it.

I paired this nut with a Mossberg 6 3/4 action tube, a Magpul MOE 590 Forend and Magpul RVG. Using a Dremmel with sanding barrel and a flapper sander, I was able to open up the front of the forend "tunnel" enough to accept this nut but still remain snug to the forend. After a few test fits, I assembled the forend and installed on the Maverick. Action cycles perfectly with no slop and a huge improvement on grip and manipulation of the shotgun.

And like that, I have a great forend on a Maverick 88 setup for me and I save $30 bucks in the process!

I'm writing this review for anyone wanting to install a magpul forend on their mossberg 500 with a 6 & 3/4 inch action tube as Magpul moe forends are designed for the 7 & 3/4 action tube. Buy this nut! Some people gave the nut a low rating because they had to modify their magpul forend to get it to work.
1. This is a hogue nut designed for a hogue stock. Get over it.
2. Your trying to make a forend fit that wasn't designed for your gun. Obviously it'll take some small modification.
3. The nut is high quality and is EXACTLY what it's advertised to be. That said I haven't tried it on a hogue forend.
If you already have a magpul forend you'll notice the original nut will not slide into the front of the forend, such is the case with this hogue adapter nut as well. The magpul forend is designed with a small collar to go around the nut and then the nut jams itself against a shoulder in the front of the forend. After you buy this nut you will need to modify your magpul forend slightly so that the adapter nut will slide into the front of the forend (you'll need to remove the small "shoulder" the nut would normally press against). I did not have a dremel to do this with so I bought a small sanding drum (1/4") and stuck it on my cordless drill and began expanding the front of of the magpul forend(this is inside the forend and cannot be seen once installed). As soon as it was large enough to slip this new adaptor nut inside the forend (snug fit) the new forend fit my 6 & 3/4 action tube like it was made for it. Once you've done this there is no way to tell the magpul forend wasn't designed for your shorter action tube unless you remove it completely, look inside, and see some small sanding marks.

If you have a Mossberg 500 or Maverick 88 shotgun and you want to upgrade the hand guard - this can possible help you do it without breaking the bank. Late model Mossberg 500 and Maverick 88 models have a 1-piece slide action assembly / hand guard. This means the handguard is not meant to be removed. To get around this many people buy a replacement slide action (7 3/4" long) and then the replacement handguard of their choice to install over the new slide action tube. Some older Mossberg / Mavericks shotguns have a removable handguard, but the slide action tube is 6.75" long. Most times people also buy a replacement 7.75" slide action assembly. That's around $60-70. If you have an existing 6.75" slide action, use this nut so you can install a normal handguard - it makes up the extra length. If you need to replace your slide action assembly, you can buy a new 6.75" assembly (usually HALF the cost of the 7.75" assembly) and use this part to make it work as well.

Note: With the original nut removed from your slide tube, the handguard slides over the tube, and then you install this nut. Some clearance (5 min work with a dremel tool) was necessary when I installed an aftermarket handguard.

I used this product to fit a streamlight tl racker for end to my mossberg 500a shotgun. The shotgun is one of the older mossbergs with the 6 5 inch slide action and not the 7.5 inch slide action on the newer models. As such, the forend was an inch too long to thread to the tube. This adapter replaced the original castle but and allowed me to use the forend without having to buy a new slide action.

If you are using this nut for the Magpul forend on some Mossberg 500's, this nut will not go through the Magpul forend opening without expanding the Magpul opening. It is not difficult and is the best solution to avoid replacing the slide action tube. A simple Dremel tool with a 1/4 or 1/2 inch wide circular sanding wheel just applied in a circular motion to the inside diameter of the forend opening going about an inch deep will enable this nut to slide all the way into the Magpul and enable you to connect to the shorter action tube. It is not difficult and worth the reward.

I got this for my Mossberg 500. It screws right on and fits perfectly. If you're using it for the Magpul forend you will have to grind out the inside of the tube where this piece sits with a dremel because its a little too big to slide into the forend. Otherwise, it went in perfectly and really improved the quality and durability of my gun.

You will need this if your Mossberg 500 has the shorter slide action tube length. That being said, I used it to install the Magpul MOE forend in FDE for the Mossberg. I was a little unsure about the using the Hogue forend adapter since there were mixed reviews regarding whether it would fit the Magpul forend. Based on my experience, it did fit BUT only after some modification. You will need to sand the inside of the forend down and maybe sand the sides of the nut so that it will slip in. The nut is too large to fit on its own. When it was all said and done, the forend locked up tight and the adapter nut did its job.

Fit Great

Worked perfectly for my Mossy. Since the newer 500s come with a cheap slide tube assembly that is all in one (at least the one I bought did) This came in handy when switching it out for the older style (better IMO).

Money-saving solution

Adding this to a shorter action tube is way more cost-effective than buying the longer tube. I used it to add a 7 5/8" Houge forend to my Maverick 88 with a 6 3/4" action slide tube.

Saved me money!

Worked for what it was needed for. Was able to use a smaller slide tube in my Mav 88 and upgrade to Magpul furniture. Will need some modifying, but nothing a dremel can't handle.

Used it to put on magpul forend.

It says it doesn't fit and it's right. But sandpaper on a socket or a dremel with a flap wheel and this will hold your magpul forend on instead of spending more on the action slide tube.

I have a older Mossberg 500 with the short 6 3/4 action tube, which is pretty limited on the forends that you can buy. I dont care for the shorty forends.
I was looking at the 7 3/4 action tube assemblies, so i had a much bigger choice on forends to pick from, but every place i looked was out of stock.
Then i came across the Hogue adapter nut, it is ment to be used to install a Hogue overmolded forend on older Mossberg 500's and 835 and 590 shotguns.
But it opens up other options as well if you have the 6 3/4 action slide and this adapter nut.
I purchased a Choate 7 3/4 forend, it is made to use the oem shallow shouldered forend nut, so the Hogue adapter nut sit a inch higher in the shouldered pocket were the forend nut goes.And was 1 inch away from the threads on the action tube.
This was easily fixed, just use a drill press with a 1 1/4 holesaw installed, deepin the shouldered nut area another inch or just a tab over, clean up the inside and install, onley takes 3-4 minutes and it allows you to use just about every 7 3/4 forend on the market on a 500 or 590 with a 6 3/4 action tube.
You can also use a 1 1/4 holesaw for metal on the new aluminum forends , just go slowly and have the forend secure.
Thank you Hogue.
