Swampfox Optics SENTINEL II Micro Reflex Sight – 3 MOA Dot w/Backup Blacked Out Irons (Red or Green Dot)


SKU: Swampfox_SNL2120 Categories: , ,


Crafted for precision and built to stand guard, Sentinel II showcases a fusion of advanced features in a sleek, cohesive design. Designed for concealed carry, this micro pistol dot sight maintains the standardized RMSc footprint and its familiar slimline profile while maximizing visibility with a larger 20mm window. Its most unique feature is the patented removable rear sight guide installed in front of the window. This guide provides backup support for micro pistols that sacrifice their rear iron sights for dot sight compatibility. Sentinel II displays a 3 MOA dot in either red or green illumination and is equipped with Swampfox’s Shake N’ Wake auto on/off feature for grab-and-go readiness.

The RMSc footprint provides compatibility for most optics-ready slimline pistols while its recessed hood design and shielding lens coatings protect its larger viewing window. Sentinel II stands as the latest advancement in Swampfox micro red dots.

Despite its slim RMSc mounting footprint, Sentinel II maximizes visibility for quick target acquisition with a new 20mm objective window – an improvement over the 16mm lens of the first generation optic. Fully multi-coated to resist scratches, fog, and water, and protected from glare by rear hood serrations, experience improved clarity no matter the shooting conditions.

Sentinel II is uniquely equipped with patented removable rear sight guides from Night Fision. Installed forward of the optic window with titanium screws, the hardened steel and black nitrided precision guides not only act as an alignment tool but also as a distinct landmark for those familiar with traditional iron sights.

Featuring a crisp 3 MOA dot in either red or green and 10 manual illumination settings, Sentinel II stays at the ready longer with a bottom-mounted CR2023 battery and Shake N’ Wake auto on/off. Brightness settings 1 and 2 are night vision-compatible with settings 3 to 8 for low-light and indoor applications, leaving settings 9 and 10 ideal for daylight shooting.

Manufactured from tough 7075-T6 aluminum, Sentinel II offers improved durability over its previous generation. A new body design better protects the LED emitter from the elements and provides enhanced protection for its recessed lens against surface racking. Armed with robust design features and optional add-on Ironsides Shield, Sentinel II is capable of withstanding everyday use and abuse.
