*Earlier ONE suppressors had 28 TPI threads of the same diameter as the later 24 TPI cans.   You will need to determine which threads your suppressor has before ordering.  We do not know of any way to identify these besides gauging/measuring the thread pitch of the tube or an existing adapter, and attempting to install one with the incorrect threads may result in damage to the adapter and/or the suppressor.   Our Return, Refund & Exchange policy applies to this adapter if you order with the incorrect threads for your application:   https://www.eccomachine.net/refund_returns/
