The 9mm Bore Sight uses 3 of the smaller L626/AG4 batteries, so the laser output is limited in time. Make sure that you have the pistol set up to do your adjustments quickly as the battery life is 5-15 minutes depending upon battery output. Must use alkaline batteries with the BS9.
Compatible with the accessory MBP9 Modular Battery Pack 9mm that allows you to convert the BS9 to the MBS9 and runs on 2 AAA batteries for much longer battery life. Not included.
