Due to old age and accompanying decline in eyesite, I am entertaining the thought of installing a red dot type sight on my Ruger 44 carbine. I have looked at all the logical sites like midway, weaver, leupold, redfield, DNZ products and cheaper than dirt, but cannot find a one piece base that will fit the carbine. I can find the 2 piece set at weaver but the red dot type sights are not long enough to reach both ramps. I called Ruger hoping the receiver on the 10/22 might have the same radius as the 44 carbine and I would be able to use the readily availble 10/22 ramp, but no such luck. Does anyone have any suggestions or a base they would like to depart with?
