School me on muzzle threads

[timattalon]

So I have been wondering this for a while. I understand the difference between threads, the fact that there are a certain amount of turns cut per inch etc. What I don’t know is what the different threads are used for? Can any thread be cut into any barrel? Are some threads used for specific barrels? I’m looking to cut down my .223, but also want to replace the current gunworks suppressor for a dpt. I have passed up on a few second hand supressors in the past because they were the wrong thread for the rifle. Can I buy another threaded suppressor and cut the barrel to suit?

With my limited experience, most threads I see are 1/2" UNF but when you get up to about 30 cal a lot of them do 9/16ths . The reason for the size difference is the internal distance from the bottom/deepest part of the cut, is not much bigger than the bore

My usual advice is to get a thread cut by whoever makes your suppressor. While threads are supposed to be standardised there may be subtle variations in it that vary.

And may I ask why you want DPT over the Gunworks? On a 223 performance would be very similar in both I would have thought....
