I assume you have flat tops- right?
I don't make big expensive deals with mine. I use a one piece base/ring doo-hickey like the Burris PEPR. Sight that in with your favorite flavor of scope, take it off, put on regular GI type carry handle or GI Short A2 type sight and sight that in. When you hit the field, carry the sight in the case, pocket, kit bag, etc. As long as you mount each to the same tightness and the same place each time- it won't lose zero, it will always be minute of yote or better uless somebody comes along and turns a knob or wheel.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
