I stuck a Bushnell reddot on my Camper Stainless w/5.5" bbl with the rings Bushnell included but it sits too high. I dont know anything about the rings except theyre weaver style, medium 30mm. I looked everywhere for LOW 30mm rings but cant find any below about $50 a set. Medium 30mm rings grow on trees. I can find dozens of styles and prices but no LOW 30mm. I called Bushnell and they agreed to send me a set of low 30mm rings but I just got a letter from them telling me theyre backordered. I can find dang near anything in the world I want off the internet except low 30mm rings for around $10. That I can't find. 30mm waever rings are like good tomatos in February. There aint none.
