Great information RW.

I will add this to my web site links under Gun Smithing where I have lots of other thread pitch and barrel tenon information,if you don't mind.

No one can remember all of this type of information, so it is nice to have a reference to go to.

Thanks

Thank you for the information. I see this is a new section to LRH. I can't post in this forum and please redirect me if I am posting in the wrong section. I am trying to build a 300 blackout. Can I build a suppressor? Would you recommend building your own?

I can help for sure. You can build your own if you file a Form 1 first. Still runs you $200 to the GOVT. If your not a accomplished machinist I would purchase one.
Feel free to call me at 816-718-9489. I can give you the long and short of making VS's purchasing one.

Thanks

You should check the links on your website as I found several broken ones. Also, Steve's pages require a login.
