What is the thread pitch and size on an original Galil ?
Does any one also know what the vortex thread and pitch is ?
I uncrewed the Vortex and went to replace it with an original Galil, the original Galil
was much larger hole diameter (in the FH ) and finer thread.
It looks like I will need to make an adapter or bushing the put the galil FH on this barrel.

Galil 13x1.0 right hand metric. Vortex I believe is 1/2x28 right hand inch.

FH is sorted out.
The 2 galil FH I have ( Ported and slotted ) are both 1/2 - 24 RH
The Phantom is also 1/2 - 24 RH just FUBAR by the angry beavers at CAI.
I was able to clean up the barrel and FH threads with a tap and die.
The barrel threads were savable, but I may shorten it by 1/4" and cut a 1/4" of new threads.
I will have to check the barrel length and make sure I can do it and be legal.
If not it will just have to do.
