I have stopped by and talked to them at the last couple of SHOT shows. They are really an OEM barrel maker and like to think that they will become a gunsmith supplier. They have extremely limited offerings with respect to contours and especially twist rates. Generally, they have one twist rate per caliber, like 1-10 for 30 cal. They are, obviously, button rifled barrels as they were set up and tried to replicate a lot of Shilen processes.
I went back on the last day of SHOT this year to try and discuss some things with them and possibly order a couple of barrels to try and they had abandoned their booth! All their barrels and displays were still up but I guess the exhibitors were out checking out other stuff!
