The flash suppressor is not threaded. The barrel is.

To clarify, the flash supressor is held on by the castle nut to the threaded barrel. There are no threads inside the flash supressor.

They are right hand threads, but I don't know the pitch. It is at least 32, maybe higher.

I'm not entirely sure what you're asking but the barrel is threaded 0.595" -32NS 3A threads for the castle nut according to Kuhnhausen's shop manual.

You need to use a thread gage from a tap & die set. That will give you the thread count.

M1AalltheWay answered your question, mostly. This is not a standard thread for which you can get a tap/die from the hardware store. Here's what the spec.means:
0.595: nominal diameter of threads
32: threads per inch (this is what the thread gauge from your tap & die set will tell you, but it's not the whole story)
NS: Type of thread (he may have truncated from "UNS" which indicates a "special" thread)
3A: Tolerance class ("3" indicates a tight tolerance, "A" indicates an external thread)

Do you have a problem with the threads on your barrel? A few months ago someone had a problem and I think he actually had a die made. If memory serves me correct it cost him a 100 bucks. Try using the search thread feature, he may loan it to you if there is a problem with yours.

Guess what? I found the thread and that guy was one of the top M14 gunsmiths in the country. His name is Ted Brown dba Shooters Den. He paid $90 bucks for the die and I dont think it will be loaned but I am sure you can send the barrel to him to get chased. Here is the thread
http://m14tfl.com/upload/showthread....hlight=tap+die
His info can be found in the sticky "armorers that work on the M14" He is a great guy. I think he may just be getting back from vacation/work right about now so try giving him a call if you need his services.
Hope this helps

Nah. Not too much of one. If it comes to it I will dig up this thread thank you guys. The castle nut has problems if I take it off. so I simply will not take it off anymore at all. Nothing much just gets a tad hung up from time to time.

it is times like these I wish I got a ptr-91 & make me wanna sell my gun.. but i would want too much for it cause I would wanna sell all the accessories too lol. but then i would miss it eh? xD

I assure you, you will miss it even if the threads are loose and its bothering you. If it came down to it just leave it off the barrel and get one of those new fancy smith enterprise gas lock front sights. But dont get rid of it.

but I really like PTr-91s lol.

and I also have some off fixation on getting a new barrel on my m1a >.> haha my m1a makes me thing weird. perhaps it is.. love 0__O I should have jsut gotten a fulton armory with medium weight or chromed barrel. I really like chromed barrels. what is the life on a standard SA m14 (march 2005 production)? how long will it do for a 100 - 300 yard shooter before needs a change? I know it goes out of NM standards after about 5000 - 8000.. or so i have read.
