Any experience with red dot sights. I'm going to be doing most of my shooting under 20yds, but the open sights on my qb57 seem hard to focus on. I was figuring that for snap shooting a reflex red dot would be the way to go. How much would I need to spend to get a decent one. Are they durable, are they accurate up to 40 yds, any other points of view or experience would be welcome.
