What thread for suppressor

[Timmay]

Hi all
I will be grabbing a new DPT Mk2 Overbarrel suppressor for my Model 7, I want to use it on two different rifles, one will be chopped back 95mm from muzzle (to retain OAL of factory) the other rifle will be left at standard length with the muzzle threaded. The barrel starts at 13.8mm (for non chopped rifle) and is 14.3mm where I intend to chop the other rifle.
All I know about threads is lefty loosey righty tighty... What size threaded suppressor should I order from the DPT site?
Cheers
