Swampfox Optics Snl2120Gmt Sentinel Ii 1X 3 Moa Green Laser

The Swampfox Optics Sentinel II is a compact pistol red dot sight built for shooters who demand both speed and reliability in a concealed carry package. Designed around the standardized RMSc footprint, this micro pistol dot sight delivers the familiar slim profile that works with modern carry-ready slides, while the enlarged 20mm objective window gives you significantly better sight picture than older 16mm designs. The 3 MOA green dot reticle cuts through glare and tracks targets fast—perfect for home defense, duty carry, or quick-action range work where every millisecond counts.

What sets the Sentinel II apart is its patented removable rear sight guide. This feature lives in front of the objective window and gives your backup irons a solid reference point, even on micro pistols that ditched their rear sights entirely for dot-sight compatibility. That's genuine co-witness insurance when electronics matter most. The Shake N' Wake auto on/off system keeps the dot powered down until you move the gun, so you grab it ready to go without burning battery life on a shelf.

Swampfox didn't cut corners on durability. The Sentinel II is machined from 7075-T6 aluminum and fully multi-coated to shrug off scratches, fog, and water. The redesigned body sits the LED further back from the elements and protects the recessed lens from accidental racking—real-world toughness for a gun that sees real use. Rear hood serrations kill glare and reflections. Pair it with the optional Ironsides Shield for even more impact resistance, or run it standalone on any RMSc-mount compatible pistol.

Frequently Asked Questions

What pistols is the Sentinel II compatible with?

The Sentinel II uses the RMSc mounting footprint, which works with all modern carry-ready slides designed for that standard. Confirm your pistol accepts RMSc-pattern dots before purchase.

Does it work with my backup iron sights?

Yes—that's the whole point of the patented removable rear sight guide. It gives your backup irons a reference point even on micro pistols that sacrificed their rear sights for dot compatibility. This guide mounts in front of the objective window and helps you maintain sight alignment during transitions.

How long does the battery last with Shake N' Wake?

The Shake N' Wake auto on/off feature reduces unnecessary battery drain by powering down when the gun sits still. This extends runtime significantly compared to always-on sights, but we don't have a specific runtime figure to give you—check with Swampfox for detailed battery life specs.

Can I add extra protection to the Sentinel II?

Yes. Swampfox offers the optional Ironsides Shield as an add-on accessory that provides additional impact resistance and protection for the optic during hard carry or training.
