Ak74 muzzle brake fouled on

[jeepnuts]

help,

Stuck muzzle brake on my ak74. I am sure is it due to fouling, carbon, rust or a combination of the three. I failed to remove and clean it after a shooting session or three and now have a stuck brake.

It used to come off by hand, easily. I have tried the basic cleaning / penetrating chems that I have laying around and can’t get it off.

What should I try? Hoping there is a chem that will get it loose

I haven’t used any big tools because I don’t want to tweak the front sight base or the barrel. I’ve only used a piece of rubber coated metal through the holes and tried turning it.

I found out the hard way as well...mine's still stuck.

Maybe work on in one day. Hard part is holding in the detent pin while turning.

I use a razor blade to hold the detent down while I have the rifle secured so I can stick the large channel lock handle (rubber coated) thru the brake.

Using the screwdriver from the AK cleaning kit works well for the pin. Lay it flat against the pin, with fingers on the screwdriver on both sides of the barrel.

Kroil is one of the very best penetrating oils. Well worth soaking overnight.

That's what I was gonna say. Kroil, then some heat, then some more Kroil. Heat will work with capillary action and Kroil will get into the smallest places you can imagine.

I use to like Kroil, but it could not bust loose what PB Blaster could.

I've tried PB, but for my problems, (mainly cars, motorcylces and boats), Kroil seems to work best for me YVMV

So far no luck with it soaking in Kroil for 24 hours. Thanks again for the tips

You're twisting it the correct direction to remove aren't you?

I'd hate to think your actually tightening it...
