The Lantac Dragon Muzzle Brake 9mm version is for 1/2x36 threaded muzzles and will not fit the 1/2x28 threads of the CZ Scorpion.
It depends on the muzzle threading, if it is 5/8x24 threaded MPN: DGN762B would work.
These Lantac Dragon Muzzle Brakes will not fit a Henry Big Boy in 357 Magnum with a barrel that has 5/8x24 threads. You will need a muzzle brake that is for .357 caliber or larger and uses that thread pattern. The guide at the link below will provide information on selecting a muzzle device.

Yes, the .308 model of the Lantac Dragon Muzzle Brake can be used on a Remington 700 SPS in .308 as long as your barrel is threaded 5/8x24.
From what information I could find the Zasatva M90 is chambered in 5.56 but the manufacturer doesn't state the barrel thread pattern. The 5.56 model of the Lantac Dragon Muzzle Brake will work if the M90 barrel is threaded for 1/2x28 to match the threads of the Lantac Dragon Muzzle Brake.
The 7.62x39 model of the Lantac Dragon Muzzle Brake should fit a IO M214. However, I could not find any information regarding the barrel threads of that rifle. So if your IO M214 barrel is threaded M14x1 LH it will work the the 7.62x39 model of the Lantac Dragon Muzzle Brake.
The Lantac Dragon Muzzle Brake 7.62x39mm model should fit a Zastava M70 if the barrel matches the M14x1 LH threads of the Lantac Dragon Muzzle Brake. If your muzzle device is pinned and welded then no muzzle device can be placed on the barrel.
The Lantac Dragon Muzzle Brake will work on an Smith and Wesson M&P10, but you will need to make sure you select the .308 model and make sure the threads on your barrel are 5/8x24. This is Lantac Dragon Muzzle Brake model DGN762B. So AR10's are not as universal or parts compatible like AR15's. There are a lot of variance between AR10's and their components. So certain AR10 parts or upgrades that may be compatible with one brand rifle may not be compatible with yours. However, there are most likely a variety of interchangeable parts with your rifle, you just will have to do some research before to ensure they will work. When it comes to modifications, this all depends on what your are going to be using the rifle for as well as personally preference.
The 7.62x39mm model of the Lantac Dragon Muzzle Brake may work on a WASR-10. You would just need to verify that the barrel threads match the Lantac Dragon Muzzle Brake.
The B&T Quick Detach RBS Suppressor may work with the Lantac Dragon Muzzle Brake. I recommend contacting the manufacturer to confirm compatibility.
