I have attempted to boresight 2 scopes on 2 different guns with 2 different laser boresighters. Both scopes run out of movement before either will come up enough to center on the reticle. I have tried both scopes on both guns with the same result. One boresighter is a LaserLyte that goes in the muzzle and the other is an AimShot that goes in the chamber. Can some one please give me some input what the problem may be?
