I've handled these rifles at the SHOT Show and NRA Annual meeting. I own three of their rifles: XWR-SS .270 WSM, XWR-SS .300 Win Mag, and a Custom .338 Lapua. I'm very happy with all of them. Also, my brother bought a custom Woodland .257 Rob. The Xtreme Vantage Rifle (XVR) line is a follow-on from the Xtreme Weather Rifle (XWR) line with a heavier contour barrel and iron sights.
I know Dave Petzal shot their Vantage Rifle at SHOT Range Day and really liked it.
