That's what I use at DSG to bore sight customers rifles. They work just fine, but as Vellnueve pointed out, they are not an exact science. You may get lucky, but plan on the bore sighter getting you on a piece of typing paper at 50-yards, then go from there. If you laser bore sight your gun to zero, then tweak the bore sighter 1/2 turn, you'll be off. Every once in a while I get lucky and have a customer report that he needed to make no adjustments whatsoever, but that's the exception rather than the rule. I find the lasers to be far easier to use and produce better results than optical...I didn't check, but if that price includes shipping, (or shipping is cheap) it's a good deal.
