My thought when I talk to Kenny (Mag-na-Port) today is add a machined bell end on the Ruger 77, like Ruger installs on the Ruger American 16.5" barrel. Wouldn't be very difficult turn the end of the barrel the length of the bell plus threads so there is no taper on the barrel make a bell that will when heated slides on the barrel then let cool. Once in place finish machining it would be difficult to see the seam.
I had a machine shop been retired for 15 years. Wouldn't be difficult to do. Should have kept one lathe just to play with.
Myself 5/8" just is not enough even 11/16" is a better minimum for .451". Remember the shoulder to seat the suppressor is what is needed to be larger. If you were just adding a muzzle brake, it wouldn't matter much. Only adding about 1.5" for a brake wouldn't matter much, a suppressor is closer to 7" and $1000 plus a stamp, a lot to loose.
