Gunsmithing thread pattern of AI and Thompson Icon

[cowboy_coffee]

Just a quick question, does anyone know the barrel threads and pitch of an Accuracy Int'l and also of a Thompson Icon?

Both are short action guns. The AI i'm sure is going to be metric...just curious about the Thompson.

if the icon is the same as the venture it uses the same thread pattern as the remington 700

M18x1.5 for the AI for the muzzle. Not sure on the barrel shank to action.

Still looking to see if anyone has the answer for the Icon

I believe the Icon is 1 1/16 x 16 (1.0625 x 16). It has been a while since I have barreled one so I'm not 100% sure on that.

Hmmm.. I might have to check out the TC action, my friend pointed out how similar it was to a Sako/Tikka action.
