thanks for the suggestions. the VX2 3-9x40 is getting there, with tube length of 5.6" approaching the desired 6", and the weight at 11.2 oz is perfect. just wish i could get more tube length between the bells. i am scoping a Ruger Mk 2 and the Ruger rings don't give me any mounting flexibility. The Ruger is heavy as is, so the lighter scope is a plus compared to the Vortex which is mounted on it now.
