I wonder if that one is a suppressor...
That rifle looks darn right svelte with that barrel length.
Might be a fun project for the next chopped down 1917 I run across.
Do I see it correctly that the rifle is shortened too?
Undoubtedly.Quote:

I have not measured it. Thread form would have been what ever was common for 1920 to 1930's. I have assumed shortened rifle was made up by Soley for some reason.Quote:

So, with seven threads showing, that makes either 1/2-13 NC or 1/2-14 NPT. A little more coarse than 20TPI. And yes, I have way too much spare time today. Tom
Half inch pipe thread is much larger than 1/2” diameter. Something more in the neighborhood of .80”.Quote:
