I just bought the Laserlyte in the picture for my Saiga .308
Boresighted it a 25 yards and the dot was low, started at 25-50 and then 100yds... still had to do a lot of tuning at the range anyway...tried the reticle attachment thingie also...it seemed to help out some

aligned the rings & polishing them with the wheeler kit...got some different ammo and trying her out again...
using burris rings and swear the scopes shifting (the tick marks not moving)
maybe buying more ammo was the answer ?
