I am pulling the barrel from my AA entry and am going to have it threaded standard 5/8X24 for the Vortex QD. his way I can run my Quicksand on my .308's, .300WM and 6.5's
Until that day,

Mike Stannard at Tornado Tech did my 19.5" upper without pulling the barrel. He has jigs for that stuff and they come out great! He can do AR actions with the barrel on as well as 700 Remys, etc.
