bulgarian flash hider ?

will the 4 piece flash hiders for the 7.62mm work on a 5.56 gun?

i’ve got an arsenal slr106ur and thinking about getting the 8" barrel for it but would like to use the 4 piece on it if it will work.

Sure will.

do you happen to know what thread pitch i need for the flash hider?

All the front sight blocks are already threaded for 24mm/RH twist.

is that for the arsenal rifles? i thought i saw somewhere that they were 22mm

nevermind, i found it

thanks for the help:)
