Picked up a LASERLYTE laser boresighter this past weekend. I bought it to roughly sight in a set of M-16A2 style sights I installed on my 10/22, just to get them close before heading to the range. Being that I don't have any scoped rifles I figured this was going to be a one-time use item boy was I wrong. After bringing my sight picture in line with laser I dry fired a couple times for shits/giggles and noticed some jump to the laser dot with my trigger pull, being slightly anal retentive I could not put my rifle down until I had adjusted my trigger pull to a more acceptable level of movement. Two hours / three firearms later I came to the conclusion that this is a fun and useful training tool and possibly the best 40 bucks I have spent in quite some time.
