Featuring a red Class 3A (<5mW) 630 - 670nm laser, the Mantis® Pink Rhino™ Laser Training Cartridge delivers a consistent, reliable, instantaneous beam when struck with the firing pin, allowing you to train with your pistol using any visible laser target system or simulation. Non-marring brass construction with rubber O-rings. Requires three LR626 batteries (included). Note: To prevent damage to the o-rings, a very thin coat of oil should be applied to each o-ring. Reapply as needed. Not compatible with Ruger SR series or Hi Point pistols. Using this product with Hi Point pistols will result in damage to the sensor.
