Question about aac brake out

[mikethebike]

Im planning on putting this on my tavor.
There is one that is described as:
AAC BRAKEOUT FSC 5.56MM 51T 1/2X28

and another described as:
AAC BRAKEOUT 2.0 5.56MM 90T 1/2X28

Are they the same?

what is the difference between a 51T and a 90T?
what is the difference between the FSC version and the 2.0 version?
would either fit on a tavor?

 

[hbean]

51T AND 90T refers to two different silencer mounting threads, as far as you are concern either will work on your Tavor.

Yep, basically how many teeth the ratchet mount has, won't affect you in the least.

I'd say get whichever one is cheaper
