Crimson Trace | Rail Master

The Rail Master clips onto any Picatinny or Weaver accessory rail with four included inserts to adapt the fit across different pistols, rifles, and shotguns -⁠- one laser that actually travels between guns rather than being locked to a single host. A Class IIIA red or green laser (5mW peak) throws a beam visible to roughly 40 meters in direct sunlight and well past 400 meters at night, and a 5‑minute auto‑shutoff protects battery life if you forget to switch it off. A straightforward, genuinely portable laser sight rather than one built into a single pistol's grip.
