BSA 30mm Weaver Red Dot Sight. Integral mounting rail.
BSA 30mm Weaver Red Dot Sight with Integral mounting rail. The dot is powered by a 3V lithium battery mounted into the 11 position click rheostat which adjusts the brightness of the dot whenever necessary. Not a Scope, but much easier than open sights!
