Aimshot MBS223 Features The AimShot MBS223 projects a visible red laser down the bore using an arbor system letting shooters align a scope or iron sights with the bore axis before ever firing a shot. AimShot positions this as the system it recommends for any caliber laser bore sighting built to be more accurate more durable and longer lasting than chamber-based bore sights that rely on a cartridge-shaped insert. Because it works with arbors rather than caliber-specific chambers the MBS223 adapts to a wide range of rifles and pistols without needing a separate bore sight for every chambering. This flexibility makes it a practical tool for anyone who owns multiple firearms in different calibers. A modular battery pack extends the laser s run time to over 20 hours far beyond what typical button cell powered bore sights can offer reducing the chance of a dead battery mid-session. The unit is operable with either the included button cell batteries for a compact setup or the modular pack using two AAA batteries for extended use. Finished in black the MBS223 is built for durability through repeated use in a workshop or at the range. For shooters zeroing a new optic or verifying alignment after a scope mount change this kit saves ammunition and time by getting the first shots close to point of aim.
