I’ve been fighting to remove the muzzle break with no success. I finally got the retaining pins out. I assume it has left hand threads, but have tried turning it both directions, have tried heating it up with map gas, soaking it in water incase it was put on with Rock Set and I can’t get it to budge.

Any help from the legendary brain trust here at SIG Fourm?

TIA

A lot of AK's are left hand pitches. Unfortunately it could be either, I'd go to their website with your model and see if they say which way.

It may be Lefty-tighty.

- The flats on the end of the brake give me hope that it's threaded and only pinned, a penetrating oil of your choice and a long soak may be in order. It's been on there a long time, I'd oil it and try later. I hope you've got a vice.

Dear lord, someone help this man.

I'm only going on feel, and that only works if you're my wife or girlfriend.

They are the same person.

I can't tell from the pic. Is there a detent in the front bottom of the sight?

Unfortunately, this won't be of any help at this point, but, in the future, before you put a wrench on it, you may be able to see evidence of which direction the tightening torque was applied at the factory. The leading edge of the flats, in the direction of tightening, will likely have a sheen or other signs of wrench engagement; though a mere sheen would be rendered unusable, if the assembly was painted post-assembly. But, like I said, that's for another time. I don't have any unique AK knowledge that can help you at this point. Good luck!

SA-93's and SLR-95's (the first 2 Bulgarian imports beginning in '94) did not have a threaded barrel or muzzle brake when imported. If its threaded, it was done as a conversion after arriving. Typically, a muzzle brake was just pressed (or hammered on with a mallet), pinned, and welded or just omitted. Is there a hole in front on the sight at the top of the barrel for a spring-loaded detent? I don't see one in the photo but its not the right angle either. If there is no detent hole and no visible weld, methinks you need to whack it harder. You're going to have 2 divots in the bottom of the barrel where those pins are though.

Pace has it correct. I have an SA93, and it came without a threaded barrel. It also did not come with the spring loaded button on the front sight block.

I later "de-banned" it and added the correct FSB and threaded the barrel 14x1 LH.

In looking at pictures of the SLR95 on the internet, I see both models, plain barrel, and the ones with the OPs muzzle device. If it was added post import, I would highly doubt it is threaded, as that was after the 94 AWB, and threading was kinda taboo. I imagine that sucker has been pressed on. Your best bet may be to carefully cut it off with a dremel. Here is my old gas block that my gunsmith cut off when I de-banned it:



Wish I could offer more help. Good luck!

ETA: Looking at the picture and thinking about it a bit more, with the 2 pins, it was most certainly pressed on. The pins were there to hold it on. There are no threads.

Thanks for the info, if the barrel isn’t threaded that defeats the purpose of removing the muzzle break and cutting the break off will make the barrel less than 16” so I’m just going to keep it as is.

If you change your mind, I've seen pinned muzzle devices removed by cutting a slit (dremel or hacksaw) and splitting with a chisel.

You're probably right, though, about not bothering if there aren't threads underneath.

I took one off. It was not threaded. After removal the barrel was not shorter that 16 inches. I took mine off because I wanted to follow 922R parts count. After removing the cross pins I put the brake in a vice and turned the rifle.
