Princeton Tec Switch Rail IRRD

It screws onto the rail, without an adapter. This is the difference between this Switch Rail and the two other versions in the catalog: no mounting system to configure, a Picatinny interface and that's it.

Mounting

Direct attachment to Picatinny rail. Fewer options than the versatile mount of the MPLS versions, but also fewer parts to lose.

Two sources

• Ultrabright red LED: 10 lumens, 36 hours of battery life
• Infrared LED, invisible to the naked eye, for use with night vision devices

In both cases, the goal is the same: to see without being seen.

Controls

A single button on top, to turn on and change modes.

Body

Impact-resistant, injection-molded polymer. The manufacturer states it is resistant to splashes and rain.

Powered by two 2016 batteries.
