300 Whisper Upper + Gemtech HVT suppressor = Problem

[Archangel]

How about going to your local fitter and turner, get him to check the thread pitch with a thread gauge on your rifle and suppressor and then get him to machine up an adapter to suit..... shouldn't take any longer then 30 mins to turn it up out of a bit of 304 or 316 stainless...

I have these adapters made up already, they go from 1/2 X 36 to 5/8 X 24, they have wrench flats on them for ease of installation/removal.

I sell them for $35 shipped to the 48 states.
