Does anyone have first hand experience with the EGW Picatinny rail that mounts on the barrel sight block on a Winchester 52D or H&R M12? I've been using a Redfield 3200 12X scope and switching between both rifles. Been looking around for another vintage scope and prices are through the roof if one is found. I saw this pic rail and figure a modern scope would put me ahead if the rail works well enough. I'm a little concerned it mounts with 2 screws at only one end and cantilevers the rest of the rail. Comments?
