How to install a Weigand Weg-A-Tinny mini scope mount on a Smith & Wesson 460 XVR & mounting a Vortex Venom red dot. Also bore sighting. I sight in my revolvers at 25 yards. The Weigand scope mount replaces the rear sight on most S&W Revolvers manufactured after 1992. Fits K, L, N, and X frame revolvers that come drilled and tapped from the factory.
Torque specs (all with blue Loctite):
--Weigand scope mount to revolver: 13 in.-lbs.
--Vortex mount to Weigand base: 30 in.-lbs.
--Vortex Venom red dot to Vortex mount: 20 in.-lbs.
