The CMR-203 Rail Master® Universal Green Laser Sight is an instantly-activated universal laser sight that is designed to fit M1919 Picatinny or Weaver rail-equipped handguns, rifles, and shotguns.  The CMR-203 marks Crimson Trace’s first universal fit green laser platform and is built with the industry-leading quality, ergonomics, and fit that Crimson Trace is known for.

An excellent addition to the extremely popular Rail Master family of products, the CMR-203 will please both novice and expert shooters alike with its excellent versatility and dependability, which includes adjustable activation locations and a compact, rugged design.

The human eye processes the color green more than any other color and Crimson Trace offers the brightest green laser allowed by law, (5mW peak, 532nm, Class 3R).  Additionally, the CMR-203 provides two hours of run time on (1) CR2 lithium battery and includes an Auto Shut Off feature at 5 minutes to preserve battery life.

As with all Rail Master products, the CMR-203 is quickly user-installed in moments, (with included hardware and inserts), and can be easily transferred from firearm to firearm.  The unit is securely fastened once installed because of Crimson Trace’s unique Secure Lock Technology™ (SLT™).
