I want to swap my Ergo forearm to the Hogue to match the Hogue stock, but couldn't loosen the nut. I used a bit of loctite when I installed the Ergo, so that makes it even harder for me to remove now.

Any ideas for a make-shift tool? I understand MagPul includes a tool to remove that nut with their forearm. Any of you have that tool lying around I can borrow?

I eventually had to craft one out of a cut up section of angle iron and some vise grips. Yeah, I’m sure there’s a dedicated tool for it, but this was in the dark days before 56k dialup. After the fits I had trying to get it off in the first place, I can’t imagine using loctite on that nut! Good luck.

Guess I'm confused. An 870 forearm is held in place by a magazine cap that is hand tightened. This is removed and the forearm comes off and from there you can break the gun down for cleaning or repair. Are you saying you loctited the magazine cap.

I am pretty sure he is talking about removing the forend part from the forend tube assembly. There is a special tool that makes removing the retention nut much easier than other methods, especially if one has used thread locker on the nut for some (odd) reason.

As such tools go, it’s fairly inexpensive and useful to have to completely disassemble the forend for cleaning, maintenance, or switching parts.

If and when you get it off, I advise not using loctite when you reinstall it. It really isn’t necessary, and as you’ve discovered, makes removal a challenge.

Yeah, it's the screw ring at the end of the forearm to keep it in place.

It unscrewed easily when I installed the Ergo, so I put in a bit of blue loctite in case it backs out after so many pumps.

I should have at least made sure I like the new setup first. Live and learn.

I might try heating it up with a match and see if it loosen up the loctite.

Brownells does make a tool. About $30 bucks. I've never used one though.

heat.

A small mallet and a flathead screwdriver (or a brass punch if you're worried about leaving marks) has always worked just fine for me.

I can get you measurements from my tool if you want to make one. Alternately, I could loan mine to you.

Try needle nose pliers.

This works, especially one with the curved tongs....make sure you have a mallet ready as well

Heat up a tool to Tansfer heat to ring. Not open flame.
Good luck

Proper tool for a proper job. I have an ATI wrench, but it's discontinued. I've used it many times and never had a spanner nut that I couldn't remove.

The one Sigfreund posed is good.

This one should work well too...

I have a spare Magpul one if you need it. Send me your address and I'l get it out to you.

I found last week that a regular QD sling swivel fits that screw slot just about perfectly. It may not give you enough leverage if you've Loctited the screw, but in a pinch it fits.

Every one I tried to swap out was a bitch to get off. When I went thru the Remington Armorer course, I tried to get them to fess up with a tool. No joy! I eventually bought a tool from Brownells.

The forend tube, which is attached to the left and right action bars, uses a forend tube nut that takes a special tool. If you want to remove the wooden (or plastic forend), you have to loosen the forend tube nut with the special nut. Has nothing to do with the magazine cap.

I used a big flat washer and turned it with a crescent wrench.

Always used the tool from brownells. Once in a blue moon I'd come across one that was so butchered up from using needle nose pliers or something that just wasn't made for it that it was easier to just replace the nut and action bars vs spending hours trying to save parts that weren't that much.

If you get the tool from brownells you won't even have to bother with loctite, just grease the threads for the future, and tighten down. It'll never back off itself on you.

I have used a nail cut to length. Insert into slot, use pliers to twist.
