Hi all. I have just acquired a new rifle and was assured that it had a 1/2 unf thread. Lovely I thought that will fit my mod i have already. Tried fitting it tonight and low and behold its the wrong thread size.
So is there a way of measuring the thread without buying a special tool if one even exists.
I have measured the screwcut section and from crown to face where the mod should stop is 14 mm. Is this measurement of use or do I need a diameter or count the threads etc.
Also if a rifle is factory screw cut and then proofed is there a proofing stamp just near the action. Or if it is after market screw cut and then reproofed is there a stamp on the muzzle end of the barrel.
All in all I'm a bit miffed as I was told it was factory screw cut ( not sure it was ) and half inch unf.
Needless to say the dealer will be contacted. But in the mean time thanks in advance for your help.
Also can I buy a different thread section for my a tec mod
