Anyone used the Czech Special Forces Muzzle Brake System for VZ 58 / CZ 858 that Corwin Arms carries?

I'm assuming by the price of $87 that it will superior to the $35 options they carry.. Also open to suggestions for other good Vz 58 muzzle brake options out there.
 
I don't know if it's necessarily superior to other muzzle brakes but I do use it on my CSA Vz.58 and it does work quite well. Honestly, for me it was mostly aesthetics that prompted to buy it...it's not like x39 has any real recoil.

I will say that people standing alongside me certainly feel concussion when I shoot...for whatever that's worth.
 
I got mine from corwin after doing some research. Found a couple of YouTube videos where several brands/styles were tested. And the special forces brake consistently came on top. In the process I also found some videos of over compensating slant brakes.

My experience with its performance has been very good. Very little to no muzzle rise and no muzzle flash that I can perceive. When I haven't cleaned it in a while and crud begins to build up inside it, you'll start seeing sparks coming out of it every now and then. I have theorized that this are ignited crud fragments coming out of it.

Which brings me to its "weakness". Because it is a 2 part brake, gases and burnt residue have a complex, non linear path out. After 200 to 300 rounds, hard black carbon crud starts to build up in between the two parts. That crud is not easy to remove using traditional solvents and gun brushes. I finally resorted to grabbing a flat file and scraping it off. So far it seems to be the best and fastest method of cleaning. The cleaning is all internal so the outer finish is not affected.

If you have an M14/M1A/M305 this is like the cleaning of the insides of the gas plug and the inside of the gas piston. The crud that builds up there is very similar and the standard cleaning procedure involves scraping it off with hand held drill bits.

While this brake performs very well reducing muzzle rise, recoil and flash, other simpler brakes may not build up the crud this one does.
 
I can't compare it to other brakes for the CZ858. because it's the only brake I have for mine.

But it does a very good job of keeping the gun flat while firing. For me, it isn't about reducing recoil, it's all about keeping the muzzle flip to an absolute minimum - makes for quicker follow up shots.

For cleaning, I just throw the whole thing in the sonic bath for a cycle, that loosens it up enough to unscrew the two different parts. A second run through after that removes everything from the threads and hard to get places. Blast it with the air-compressor and done.

What you DON'T want to do is lube it or oil it in any way. The oil will just collect extra fouling, and the oil will also cook and harden very quickly during firing, just making things worse.

$85 is peanuts compared to what you can dole out for a fancy brake on an AR, so keep that perspective in mind.

I learned this the hard way. I lightly oiled it the first time I assembled it and the crud build up was much faster than what it is now.

I dab a little bit of anti seize on the threads and have not had any trouble disassembling for cleanup. I do the same thing with my M14/M305 gas plug.

I wish I had thought of doing that back when I first got it...mine is on there and I think only God or a MOAB is going to get it off now.

It's an East Bloc gun. Use a playing card to hold back the spring loaded set pin. Fit a crescent wrench over the brake Hit crescent wrench with a hammer. Upsize hammer until success achieved.
 
I have a old school jar of diesel in my garage hard to clean parts I just soak for the night. It does the trick
 
Warning on muzzle breaks is they throw off were your bullets land, Makes it very frustrating for irons or scope because it can/will run out of adjustment if its drastic.

Super nice smooth shooting tho, follow up shots are easier and less kick. They all work good except the 25$ slanted break.

In the end, mine has none now. Just preference.
