What are some of the best and worth the cost?
Mainly just want to reduce recoil.
So far I am interested in the AK74 muzzle brake, but that is really all I know. I hear they are one of the best and they reduce recoil a lot and it also redirects the flash to the sides so it kind of does both jobs.
Also any websites for the best deal are appreciated.
Thanks

And by the way, is there any advantages of a 24x1 mm thread/muzzle brake over a 14x1mm lh or rh one?
Reason I ask is why don't they just make all the AK47's the same. Also I seen that the 24mm one is longer as well as fatter than the 14mm.
Do any of the sizes in the AK-74 style brake have advantages? Handles the better, more sturdier, reduces more recoil and/or flash?

Sorry I am new to firearms and just want to get the right things so I am not wasting any money on the not-so-good stuff.
Thanks for the help.
Also do any of these affect accuracy at all? In a positive or negative way?
Not talking about rapid fire or fast follow up shot accuracy, but as far as effective range.
