Thanx guys. ya Rat Patrol it is an old set of rings.1 cheapo AA flash light with a 3d mag lite bulb wired to 6volt battery.I would like to put pressure switch.it is pretty bright it reaches the fence property line in my back yard easily about 25-30 yrds.I also use old scope cap + red tailight tape as a filter.I know you can buy rigs like this but this was stuff I had at hand.
