Swampfox Sentinel Ii 1X20 Micro Red Dot 3 Moa Stealth Tritium Rear / Shake

The Swampfox Sentinel II 1x20 micro red dot is a compact pistol sight engineered for shooters who demand both speed and reliability in a carry-ready package. Built on the RMSc footprint that's become the standard for modern micro optics, this sight pairs a slim profile with a larger 20mm objective window—a meaningful upgrade from earlier generations—to give you better light gathering and a wider sight picture when you need it most. The 3 MOA red dot balances precision and speed for close-quarters work, while the Shake N' Wake feature keeps your battery fresh by powering down when the gun sits still and firing back up the moment you move.

What sets the Sentinel II apart is its integrated rear sight guide, a patented addition mounted in front of the window that serves as a backup for pistols forced to sacrifice their factory rear iron sights for optics mounting. That means you've got a fighting chance even if the electronics fail or the battery dies. The optic is machined from 7075-T6 aluminum for durability that matches the demands of daily carry and training, and the multi-coated lens resists scratches, fog, and water while rear hood serrations cut glare. A recessed lens design and updated body shape protect the emitter and glass from accidental contact during racking or holstering—real-world concerns for a carry gun.

This is a working optic for working shooters: no bloat, no gimmicks, just a sight that's tough enough to stay with your gun through whatever you throw at it.

Frequently Asked Questions

What pistols does the Sentinel II fit?

The Swampfox Sentinel II uses the standard RMSc mounting footprint, so it's compatible with any modern pistol that accepts RMSc-pattern optics. Check your pistol's manual or optics compatibility guide to confirm.

Does it work if my iron sights are removed?

Yes—that's the whole point of the rear sight backup guide. If your pistol requires you to ditch your factory rear sight to mount the optic, the Sentinel II's integrated guide gives you a makeshift backup sight if the electronic dot goes down.

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

The Shake N' Wake feature automatically turns the dot off when stationary and back on when the gun moves, which extends battery life significantly compared to a always-on design. Specific run time depends on your usage and battery type, but the auto on/off system is designed to keep you from draining the cell during storage.

Is this sight durable enough for carry?

Yes. It's built from 7075-T6 aluminum, the same material used in precision rifle components, and the recessed lens plus updated emitter housing are designed to protect the glass and electronics from the bumps and snags of daily carry and holstering.
