Thread shoulder

[il_cop]

Just got my Tikka 243 back from the smith... I had it cut to 17" and he threaded it 5/8-24, but the shoulder is .675

I told him I didn't know what the barrel diameter would be at 17 so if there's not enough shoulder, thread it 1/2-28. Something got lost in translation.

This is only .05 over the thread major. Not much of a shoulder.

Any remedy other than chopping another 1/2 inch and rethreading 1/2-28?

This rifle will have an OG 6.5 on it, if that info is helpful

I'm guessing the relief cut at the shoulder would preclude you from extending the 5/8-24 threads to add on a shoulder but maybe someone with more machining experience can confirm that.

You're probably stuck chopping it again.

Thread 'Does this barrel have enough shoulder for Suppressor?'

May 9, 2024

I am going to run a suppressor on my Tikka T3 Lite in 6.5CM with a 20 inch barrel. I got the barrel threaded by a local gunsmith in 5/8x24. He told me the shoulder would be smaller, but he wouldn’t have a problem running that thread size on my gun. Cool, the professional thinks 5/8x24 will work well.

I just got the gun back and thought “wow, that shoulder is tiny!”

I am no gunsmith, but this shoulder seems very small…would you be comfortable running these threads for a suppressor, or would you go back and get this done in 1/2x28?

I would want my suppressor in hand to check how it shoulders

I know I would prefer to have 1/2-28 over a 0.050" shoulder
ETA id still be tempted to try it with 0.050" shoulder vs spending another $100 to re thread
