I am trying to help a friend fix his AR. When he installed the bullet button, it was adjusted wrong. It will not hold a full mag in the magwell if you give it a soft tug. I tried to adjust it for him, but the black cylindrical nut is stuck. He used blue loctite so it wouldn't vibrate loose, but not I can't get it off. I used a red bullet button wrench that had the threads removed as the removal tool, but that failed. The little "fingers" broke off. I tried the silver bullet button tool, but the same thing happened. The nut is also starting to get chewed up by all the tools. I asked him if he used the blue loctite and he said he did. What can I do to get it off?

I think a little heat will break down the blue locktite but I'm not sure. Check the bottle and see if they have any solvents listed.

Use a hair dryer. Apply to bullet button for 3 to 5 minutes. Try to remove.

you may end up using a dremel tool with the cut off disc . cover the the area around the button with three or four layers of blue tape. get replacement parts and use only a pin drop of blue loctite. i dont use any and mine has been ok.

I just did this today! What I had to do is grind off with a dremel the back of the mag catch where there is a circle then punch it out. 5 min tops.

I don't think the hair dryer got hot enough. I am going to try a pencil torch.

I will do this if everything else doesn't work. I do not have an extra mag catch to replace it with.

A soldering iron works great

I stripped the lower except for the mag catch. I put it in a pot of boiling water for a couple minutes. After puting on my welding gloves, I pulled it out and the nut spun right off. Thanks for the suggestions. Now I just to wash the pot and start the pasta water all over again. Dinner wil be a little late tonight.

Soldering iron for the win, hold it onto the nut for three to five minutes and it will heat the nut/screw without heating up the surrounding stuff.

I turned the gun upside down and suspended it with books at both ends. I placed a birthday candle directly under the BB with the flame nearly touching (but not touching) the BB. If the flame touches it will produce carbon and get all over the finish.

after 3 minutes most of the loctite has dripped off and OUT of the rifle.. Spin the nut off while hot.

The danger doing it with a hairdrayer or soldering iron is the loctite will drip DOWN into the rifle. Its not as bad as I make it sound, but I have seen the loctite drip into the Bolt catch spring and screw that up enough to force the guy to remove it and clean it also. Its a remote possibility, but its there none the less.

Dried Loctite does not turn into liquid when heated up, it just breaks down (soften up)

Now that was clever. Boiling water.

Acetone (often sold as nail polish remover) supposedly breaks it down if you ever get it somewhere that heat would be a bad idea.

Push out the lever and cut it off

If it is just a matter of the blue loctite -- use a soldering iron, point the iron tip to the bullet button screw, 'carefully and precisely' heat it to break the loctite, and then use a bullet button wrench to unscrew it.

I drilled thru the post on the back side of the mag catch where the post is pressed into the catch bar. BAM whole thing dropped out. Had to get a new mag catch but those are cheap. I would recommend this over dremel.

I know this is an old thread but ... there is no problem that cannot be made worse with a Dremel tool. Use only as an absolutely last resort.

:smilielol5: I ran into a similar issue. The guy that installed my BB, screwed it in all the way. So when I was pushing the BB it would barely release the mag. So I got one of these (http://www.amazon.com/gp/product/B008X85R6S/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1):

I used an 1/3" hex key to smoothe out the insides about halfway in. It worked like a charm! I did have to use pliers to unscrew the thing, it was really tight and I couldn't get a grip mostly because the "Wonder Wrench" is smooth in the outside.

I've had to drill one out before. Worked like a charm
