Aimshot Pistol Arbor Kit for MBS9 and MBS30 Bore Sighters 5 Piece

A bore sighter is only as good as the arbor holding it square to the bore. This five piece set adds pistol arbors for the Aimshot MBS9 and MBS30 bore sighting units, so one unit covers more handguns on the bench. Each arbor seats the unit in line with the barrel so the reference point is honest before a single round goes downrange.

Bore sighting will not replace live fire zeroing, but it gets an optic close enough that the first group lands on paper rather than somewhere in the berm, which saves ammunition and range time. Keep the set with the bore sighter and a new optic can be roughed in at the bench in a couple of minutes.
