Crimson Trace Rail Master Green Laser Sight - Universal Rail Mount
- Finish-Color:
- Black
The Crimson Trace Rail Master green laser sight is a compact, universal aiming solution for any rail-equipped pistol, rifle, or shotgun. If your firearm has a modern M1913 Picatinny or Weaver-style accessory rail, the Rail Master mounts in seconds without gunsmithing. The bright green beam cuts through most lighting conditions far more effectively than red lasers—your eye naturally picks up green wavelengths faster—making target acquisition and shot placement instinctive whether you're running a tactical setup, hunting at dusk, or training on the range.
The CMR-206 fires a 5mW peak green laser at 532nm, right at the legal Class 3R limit for maximum brightness. A single 1/3N lithium battery runs the sight for 2 hours of continuous use, and an automatic 5-minute shutoff guards against wasted power if you accidentally leave it on. Ambidextrous activation tabs live on both sides of the housing, so you can fire the laser instantly from either hand without fumbling for a hidden button. The sight also includes user-adjustable windage and elevation, so you can dial it in to match your point of aim at your preferred distance.
Crimson Trace's Secure Lock Technology (SLT) keeps the Rail Master rock-solid on the rail—no rattle, no creep. Best of all, you can move it between firearms in moments, making it an economical choice if you run multiple rail-equipped guns. Pistol shooters should note the sight requires a minimum of 1 1/16" of rail clearance forward of the recoil lug, so check your frame before ordering.

Frequently Asked Questions
Will the Rail Master fit my pistol, rifle, or shotgun?
The Rail Master works on any firearm with a modern M1913 Picatinny or Weaver-style accessory rail. For pistols, you'll need a minimum of 1 1/16" of rail space forward of the recoil lug. If your gun has a rail, you're good to go.
How long does the battery last, and what kind is it?
The CMR-206 runs for 2 hours of continuous use on a single 1/3N lithium battery. It also features a 5-minute automatic shutoff if you forget to deactivate it, which helps stretch battery life if the laser gets accidentally left on.
Can I move this sight between different firearms?
Yes. The Rail Master installs and removes without tools, so you can move it from one rail-equipped gun to another in moments. That makes it a cost-effective option if you own multiple firearms with Picatinny or Weaver rails.
Why is a green laser better than red?
The human eye detects green light more efficiently than red light across most lighting conditions. Crimson Trace's green laser at 532nm is the brightest green laser allowed by law (5mW peak, Class 3R), giving you faster target acquisition and clearer visibility whether you're indoors, outdoors, or in low light.
