The Swampfox Optics Sentinel II is a second-generation micro red dot sight built for shooters who carry concealed and demand a reliable aiming solution without sacrificing their pistol's ergonomics. This compact electronic sight maintains the standardized RMSc footprint, fitting seamlessly on modern carry guns while its slimline profile keeps your firearm trim and ready for daily use. Unlike many micro dots that force a choice between a backup sight and a mounting solution, the Sentinel II includes a patented removable rear sight guide positioned in front of the window—a smart feature for pistols that ditch iron sights entirely in favor of dot compatibility.
The 20mm lens window is notably larger than many competitors in this class, giving you a wider sight picture and faster target acquisition when speed matters. You get a clean 3 MOA red dot, 10 brightness settings to handle everything from indoor ranges to bright sunlight, and Shake N' Wake auto on/off so your sight powers up the moment you draw. The lens system features multi-coat, hydrophobic, and anti-fog coatings to keep your glass clear in wet conditions, while the 7075 aluminum housing is rated for 1500 G forces—plenty of backbone for defensive and duty applications. Waterproof to IPX 7 and backed by up to 50,000 hours on a single CR2032 battery, the Sentinel II is the kind of optic you mount and forget until you actually need it.
Whether you're running a red dot on a carry gun, setting one up on a duty pistol, or outfitting a backup firearm, this sight delivers the visibility, durability, and feature set that serious shooters expect. The rear sight guide is available in standard blackout or tritium stealth versions, giving you options based on your lighting preferences and training needs.

The Sentinel II uses the RMSc footprint, the standard mounting pattern for modern micro red dot sights. It fits any pistol with an RMSc-cut slide, including most current-generation carry and duty guns. The removable rear sight guide is designed specifically for pistols that do not have rear iron sights.
Yes. The Sentinel II is purpose-built for concealed carry with its compact slimline profile and 20mm lens window. The design minimizes print and bulk while maintaining excellent sight picture for self-defense distances.
The CR2032 battery provides up to 50,000 hours of runtime on a single cell. With the Shake N' Wake auto on/off feature, your battery conserves power until the moment you draw the gun, extending practical field life even further.
The Sentinel II offers the rear sight guide in a standard blackout version or a tritium stealth version. Tritium provides low-light visibility without batteries, while blackout is a traditional non-illuminated option. Choose based on your lighting environment and training preferences.
