As mentioned, in addtion to fixed 1x scopes, there ARE in fact scopes which dial all the way down to a TRUE 1.0 power (not 1.25 or 1.5), but also dial up to higher magnification. These are ideal for many uses, and in addition to the Nightforce, Trijicon Accupoint, and Leupold make some - perhaps others too. Trijicon's is a 1-4x24, and Leupold offers both the VX1 and VX2 in a 1-4x20 config. Bushnell even has a Banner that is a 1-4x32 - careful though, because they ALSO make a Banner which is 1.5-4x32 (for some odd reason), so you have to look around if you want the true 1x one. The true 1-4 one is typically $10 more than the 1.5-4 one.
The V3 is true 1X not so sure about the Leupolds....
For less then $150 the made in Japan Weaver classiv V3 variable (1X-3X) is a sweet little scope.
