AimShot KT-MBS Features The AimShot KT-MBS kit is built around two laser bore sight modules one chambered for 9mm and one for .30 Carbine with the .30 Carbine module doing double duty as the laser source paired with the kit s pistol caliber arbors. This setup lets a single kit cover a far wider range of calibers than a dedicated single-caliber bore sighter since the arbors adapt the one laser module to different bore diameters. Included arbors cover .38 Special .44 Remington Magnum .45 Colt .45 ACP and .500 S&W representing some of the most popular pistol and revolver chamberings on the market. Each laser module runs on a AAA battery delivering roughly 20 or more hours of battery life for repeated sighting sessions. Using the kit is straightforward: the appropriate arbor or module is inserted into the bore and the projected laser dot shows where the firearm is actually pointed relative to the sights or optic letting the shooter make adjustments before ever firing a shot. This saves ammunition and range time that would otherwise go toward walking rounds onto paper during an initial zero. Everything ships together in a zippered pouch keeping the modules and arbors organized and protected between uses rather than rattling around loose in a range bag. For pistol owners working with multiple calibers or frequently installing new sights and optics the AimShot KT-MBS offers a practical reusable way to get close to zero before live fire confirms it.
