Awesome attachment on my 3.0!
Easy to install and sight in, and once it is dialed in it stays even when you drop the Bug A Salt! Mine was knocked off of a chair and hot the floor from almost 3 feet in the air. I was sure I would hav to re-sight it in, but when I shot it at my aiming foil with the foil target with flies drawn on it from 30”. To my amazement it was still dead on! I would recommend it to any fly hunter!
