Here’s Swampfox’s announcement in full:

Clear, precise, tough, Swampfox Optics is excited to unveil its latest advancement in carry optics, the Sentinel II Micro Dot Sight. Maintaining a slimline profile and standard RMSc footprint, the second-generation optic features advanced functionality and superior construction with new, removable rear sight guide and 7075-T6 aluminum body and reinforced hood.

Engineered for everyday carry, Sentinel II features a crisp 3 MOA dot available in red or green illumination with 10 manually adjusted brightness settings. The optic’s widened 20mm lens, an upgrade over the previous generation’s 16mm window, is recessed into the hood for added durability and fully multi-coated for optimum clarity and resistance against scratches, fog, and water. Swampfox Shake N’ Wake auto on/off further optimizes run time of a bottom-loaded battery for up to 50,000 hours of grab-and-go readiness.

Installed forward of the optic window, the patented Sentinel II rear sight guide provides a guiding solution for subcompact and micro compact optic-equipped handguns missing their rear dovetail. Developed in partnership with leading tritium manufacturer, Night Fision, the rear sight guide is removable and available in complete blackout or tritium for increased visibility and precision. Matching cowitness front sights will be made available in the future for popular handgun models.

Offering an expansive 80 MOA windage and elevation adjustment range in 1 MOA clicks, shooters are well equipped to fine-tune their aim for any distance. And with tactile brightness and zeroing adjustments, Sentinel II provides user-friendly feedback even when wearing gloves and hearing protection.

      @ClintTorres Very true. Although I do like the idea of an RMSc footprint with a 20mm window. It's not worth the tradeoff to me.
