Cut barrel and Flash Supperssor

It's a good idea to get it done all at once, both the threading and cutting.

I think the 26" is a bit too long myself, so a 24" or even 22" length would get good in my opinion. They only thing you will loose is a bit of velocity, but probably not all that much. You may see an increase in accuracy, since by cutting the barrel, you are in a sense making it stiffer.

I was doing some reading on the subject awhile back. There's some good info on this page - scroll most of the way down:

There is probably a mathematical formula that could be used, but I don't think it would be a simple one!

Many people believe that the 18 - 22" barrel length for .308 is the way to go. Its shorter and stiffer. Read some of the articles on the TacOps website. They explain it a bit. The reason Palma rifles have such long barrels (26" is the minimum, usually 28 - 32") is they need the longer sight radius. Many F-Class shooters are going to short barrels as they are getting better results with the short barrels.

It is possible just to drill and pin the barrel end without actually trying to thread it. Besides.....umm there is quite a bit of legality when you place a flash suppressor or something that visually resembles a silencer on a rifle. Pinned flash suppressors are relatively easy to install your self.

If it is made correctly I am sure it would work.
The threads are a good way to place different items on the barrel.
Suppresor, Flash suppersor, Muzzle Brake, or a Thread Protector that can look like part of the barrel.
If you made a suppresor attach via a pin you would need the suppresor slip over the barrel quite a bit.
That would scuff the barrel and be noticable when the suppresor is not in place.
A Flash Suppresor or Muzzle Brake would not work without being made for that barrel and pin location.
They would also be larger than normal.
