Swampfox Sentinel Ultra Compact Micro Red Dot Sight

The Swampfox Sentinel Ultra Compact Red Dot Sight was designed to optimize every day carry on a slimline pistol slide. It is crafted of 7075 aluminum and multi-coated glass. The red dot sight offers very real advantages in defensive shooting situations. The Sentinel is available in a manual brightness setting.

Swampfox Sentinel Ultra Compact Micro Red Dot Sight Features

Real World, Real Advantage

Slide mounted red dot sights are taking the law enforcement and competition worlds by storm, and for good reason. The advantages of target focused sighting, quicker sight tracking for faster follow up shots, and increased accuracy all apply just as much to concealed carry as they do to duty or competition use. It’s a real performance boost, day or night. Two Sentinel models stand ready to meet the challenges of everyday carry. Sentinel-M is the manual press button version, and Sentinel-A features fully automatic brightness adjustment.

Manual vs. Automatic, The Choice is Yours ​​​​​​

Sentinel-M features ten manually adjusted brightness settings accessed via digital push buttons. Shake ‘N Wake motion sensing illumination preserves battery life when Sentinel-M has been motionless for about 4 minutes. As soon as motion resumes, Sentinel-M resumes its previous brightness level. Manually shut off Sentinel-M by pressing the brightness DOWN button for 3 seconds.​ Sentinel-A truly never sleeps. A photosensitive sensor on the left side of the scope body provides a bright dot relative to ambient light in all conditions, day or night. There are no manual controls at all, no Shake ‘N Wake– no way for Sentinel-A to be accidentally shut off, ever. Install the CR2032 battery underneath Sentinel-A and you’re good to go for two years straight– there’s nothing to fiddle with. ​​

Brighter Dot, Longer Battery Life

The Sentinel uses a high efficiency emitter projecting a 3 MOA red dot. Sentinel’s highest setting is brighter than any other current Swampfox red dot. ​There is no room for a robust and strong tray system with such a small footprint, so replacing Sentinel’s battery means removing the optic and potentially re-zeroing.​ ​​The good news is, deleting the tray system creates space to use a larger CR2032 battery, effectively doubling battery life.

Duty Grade

Itl is crafted from CNC machined 7075-T6 aluminum, hard coated in matte black, and features multicoated glass of the same excellent quality used in Swampfox’s long range precision rifle scopes. ​

What does it Fit?

The Sentinel is really small. About an inch tall, an inch wide, and 1.6 inches long. Shoehorned into this tiny scope is a 16mm x 16mm window, big enough for fast acquisition and sight tracking, small enough that it doesn’t affect concealability even a little. ​​Sentinel will fit Glock 43X and Glock 48 MOS, Sig P365XL, Springfield Hellcat OSP, Canik Elite SC, S&W Shield 2.0 Optics Ready, Walther PPS M2 Optics Ready– any slimline slide with an RMSc footprint incorporated, either factory or gunsmith cut.​​​


A concealed carry optic must be ultra dependable, because you are literally betting your life that it will be ready when called upon. Some pistols, like the P365XL shown opposite, have no way to co-witness iron sights once a dot is installed. If your dot goes down there are no other sights.​ ​​ Sentinel is waterproof when installed using the included flexible seal that fits between the optic and footprint. It is shock rated to an incredible 1500 G. ​​​ ​​​

Vital Stats

It features a 3 MOA red dot enclosed in a window measuring 16mm wide and 16mm tall. Sentinel fits all RMSc footprint slides and mounts. Sentinel’s 7075 aluminum body measures 0.91” wide and 1.61” long. Sentinel is very easy to conceal while still providing a window size large enough to preserve sight acquisition speed when fractions of a second count.
