Questions & Answers
Does the OPMOD variant come with a battery and charger like with the standard version? Or is it the light and switch only?

Mine came with a battery and nitecore battery charger.

Does it have a picatinny attachment? Expert Answer

No, every REIN ships with a standard inline M-LOK mount designed to work on a wide variety of hosts with M-LOK compatible rails. If a different mounting solution is required, all REINs are fully compatible with existing Scout style mounts (linked below).

Product Info for Cloud Defensive OPMOD Rein 3.0 1200 Lumens LED Weapon Light

The Cloud Defensive REIN is a leap forward in both weapon light technology and performance. With a maximum output of 1,250 lumens and 100,000 candela, targets are easily identifiable from close range and out to 300+ yards. In short, this means more light on target, improved situational awareness, and maximum penetration of photonic barriers such as smoke, fog, tint, and other light sources. The REIN represents the next generation of weapon lights.image

REIN lights now include a USB-C rechargeable battery with a built-in USB-C port. Use the included white USB-C cable to charge it. To access the battery, unscrew the light head - the battery will slide out.
