I'd use a steel Weaver base, and buy a NECG peep sight that fits Weaver scope bases. For the front, just have your gunsmith install a steel sight ramp for a Remington 700. It will likely fit, and you have the advantages of steel instead of an aluminum Williams sight ramp. They are relatively inexpensive too. With that sight combo, use a plastic XS "try" sight to figure out what height front sight you need, then install the right height XS steel BLADE front sight. (Elmer Keith taught the shooting world seventy years ago that you can't hold consistent elevation in changing light with a bead front sight, but for some reason the firearms accessory manufacturers keep trying to sell us bead front sights. There are a few companies out there that "get it", but damn few. I believe many companies think iron sights are for looks and not for using.) If you are going to use your scope in the traditional location instead of mounting a forward mounted scope, then after you get your rifle sighted in with the iron sights, put loc-tite on one of the the rear sight mounting screws, then take the sight on and off with the screw on the other side. You can then mount your scope with Warne QR rings for Weaver bases. You will need to find some secure place to carry your NECG rear peep so you can pop the scope off then mount your peep sight and be ready to go.
