The Laserlyte Mini Bore Sighter in red (Laserlyte part no. MBS-1) drops into the barrel of an unloaded rifle or handgun to project a laser down the bore for fast, ammo-free scope and iron-sight zeroing. Laserlyte built this bore sighter around a Class 3R red laser rated at a 5mW peak between 630 and 670nm, the brightest beam legally allowed, in compliance with 21 CFR 1040.10. Included caliber adapters let it fit rifles and handguns from .22 through .50 caliber with a minimum 3-inch barrel, and a daylight laser target makes fine adjustments easy to see even outdoors. It also works with the full range of Laserlyte laser trainer targets, making it a versatile addition to Schaefer Defense’s other gun accessories and parts lineup.
