First I need to say "don't get old". I went to sight in my new AR and within a couple minutes of staring through the A2 peep hole my eyes got blurry. I really want to use the iron sights primarily, but decided to PU a cheap red dot for paper punching. I got a NcStar w/see through handle mount and boresighted in my garage. The upper was in a vise and I put the dot dead nuts @ 25ft. This method (with typical rifle/scope) has always put me right on target @ 50-100 yards. Went to the range, not only did I miss the target, I shot over the friggin 4 ft high backboard @50 yds w/o touching it. Maggie's drawers we used to call it in the Marines. After several shots finally got down to about 1 ft over bull @ 50yds and the el adjustment is maxed down on the scope. Is this common? Are handle mounted red dots useless? I'm thinkin the scope is so much higher than the bore, the dot and the bore are crossing paths. I'm a retired sewer-rat (mainline pipelayer) and I set up and used lasers to lay all my pipe. This is a common prob with guys who set them up wrong, the paths cross at a given point rather than running parallel. Any help would be appreciated.
