somewhere on another thread some chaps were doing it for their pig hunting rifles.....mounted an aperture on a scope base.......... got me thinking why not fit one in reap scope base and another in the front........ pistol type site radius but enough for bush ranges. magic red lazer beam sounds like a winner to me, they work as a rangefinder too if you mount then slightly above or below scope. have beam hitting crosshair at say 100 yards then you know if you are under or over that range by where dot is in scope.....

Funnily enough, the idea of using the rail itself for both sights occurred to me when I was trolling ebay, there is a lot of stuff there cheap enough to buy on spec, just to see if it works, all sorts of barrel mounted options too, AR type stuff, but just ream the barrel mount to suit.
