The Crimson Trace Rail Master Laser is a red laser sight built to mount on any rail-equipped pistol, rifle, or shotgun with Picatinny M1913 or Weaver-style accessory rails. If you're running modern tactical hardware—whether it's a tactical shotgun for home defense, a duty pistol with a Picatinny rail, or an AR platform—this universal laser gives you a fast, reliable aiming reference that works in bright daylight, low light, and everything in between. The Rail Master's straightforward design and ambidextrous controls make it equally at home on the bench, the range, or in the field.

Activation couldn't be simpler: tap the controls on either side to turn the laser on or off instantly. The unit ships factory-sighted at 50 feet but is fully adjustable for windage and elevation, so you can dial it to your preferred zero. The 5mW red laser delivers a visible dot at typical shooting distances without eating through batteries—you'll get over four hours of runtime on a single 1/3N Lithium battery. A handy 5-minute auto-shutoff kicks in if the laser is accidentally left on, preventing dead batteries in a duty bag or safe.

Crimson Trace engineered the Rail Master to stay put. Secure-Lock Technology locks the sight firmly to your rail and keeps it there under recoil and handling. The package includes four custom inserts to dial in a perfect fit on common platforms—Glock, Ruger, Sig Sauer, Smith & Wesson, Springfield Armory, Walther, and others—with a fit guide in the box to walk you through the setup. Pistols require a minimum of 1 1/16" clearance from the recoil lug. No batteries are included.
