The normal markings you’d find on the left side of the receiver. The deep engraved safe/fire, serial number, manufacturer, etc… Right side of receivers are almost always blank, so that’s where I had the lasering done.
Shot and zero’d the Remington 700 today w/ the Vortex optic and was easily getting 1/2-3/4 groupings. Would’ve been even tighter if I adjusted the trigger for a lighter pull.
