Just got back from the rifle range - had a nearly great day - the only hiccup coming right at the end when the pin that holds my buffer tube spring broke. Cheap part to replace though.
However, I finally got the damn red dot sight zeroed in, and this was the first time I used it with the new 5x magnifier. Got everything zeroed at 25 yards, then moved up to the 100 yard range. Once I adjusted for the difference I was putting everything in about a five inch group. Not bad for a middle-aged guy with deteriorating eye sight.
Will post a shot of the targets later - I accidentally grabbed my buddy's rifle out of the car instead of mine, and the targets were in with my rifle.
