I have a Bushnell Trophy model scope with 4 seperate recticles in it which fits extremely well on my 22A or my Berretta Neo's. Its extremely easy to mount on either and has a Bullseye, a-t or a big dot or smaller red dot to choose from in sighting. Also has up to 11 different brightness ranges as well and has worked extremely well so far for me when I use it. Cost was a little over $105.00 with taxs here in Canada. The rings and mounts are with it and need NO modification of any kind at all. They just bolt right on to the rail on top and are very sturdy. Takes about a minute to mount and is not oversized for the gun as well. Everything is in the box when you buy it.
