They absolutely suck at bore sighting rifles. I bought a pair of scope rings here and happened to have the rifle and scope in my truck so the guy offered to bore sight the rifle for me. I normally have my step-dad bore sight my guns but since he was on vacation I figured why not. So in 10 minutes he has the scope on the gun and says it's ready to go.
I head over to the range, and throw up targets at 50 and 100 yards. I start at 50 figuring I'll be 3 or 4 inches off. Take a shot and nothing, after 8 shots still not on paper. Finally I get frustrated and take a shot at my brothers target who's sitting at the next bench and the bullet hits the very edge of my target. This doofus who "sighted in" my gun had it firing 5 feet left.
