Love my VMCT. I've got 2 seasons of 3 gun on it. Had to swap the cam pin for a benelli part (factory one was beat to hell after about 1500rds), and I am now using RCI xtra power carrier dog leg springs...Every now and again firing a full power slug would cause a timing issue with the lifter, ending with the shell crashing against the side of the chamber and jamming.
Rose Action Sports in KY did an excellent job opening the feed port and doing all the usual 3 gun stuff after my first season with it.
I know OP already made his choice, but for others on the M2/VM fence, at our local 3 gun there are a LOT of really hard leans and awkward shooting positions that can prevent you from having 100% perfect form. VM doesn't care...M2s, especially with small/light shooters tend to fail to extract/feed in those particular circumstances,
