For shooting 100 yards and less has anyone used a red dot plus a magnifier as your primary optic? I recently mounted and Eotech on a new 22 and was surprised at how easy it was to sight in and to shoot. However, it became apparent that some magnification was necessary at 100 yards for my 70 year old eyes. Later in the day shooting was also a problem with the Eotech alone - most so in seeing the target clearly than using the red dot. Anyone have any experience with this type of optic for 22's??
