Always Ready
You’ve done the work. You’ve taken the classes and run the drills. You don’t just shoot on the regular, you train hard when you do. You are the one they ask for help with figuring out the shot timer. Dry fire is your Zen meditation time, and every day carry is part of your lifestyle.
You are ready to step up your carry gun’s sighting system to the latest technology available. Swampfox Sentinel is ready for you.
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
Like Liberty and Justice, 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. Whether you choose Sentinel-M or Sentinel-A, expect two years of real-world battery life, even carrying your pistol all day everyday.

A FUSION OF METAL AND GLASS
DUTY GRADE? DAMN RIGHT
Other companies are producing slimline pistol dots with plastic bodies and clear polymer lenses.
No thanks. That’s not our style.
Sentinel is crafted from CNC machined 7075-T6 aluminum, hard coated in matte black, and features multicoated glass of the same excellent quality used in our long-range precision rifle scopes.


BUT WHAT DOES IT FIT?
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 the 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.
BET YOUR ASS DEPENDABLE
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 “dunk it” waterproof when installed using the included flexible seal that fits between the optic and footprint. It is shock rated to an incredible 1500 G.


GO FORTH AND SHOOT 50,000 ROUNDS
Fortune favors the prepared, right? So get out there and train hard. As the round count climbs, as you earn the holster wear on that pistol, as you replace recoil springs and mag springs, and yes batteries too, Sentinel won’t give up, and neither will we.
If shit happens and your Sentinel does stop performing within 50,000 rounds of live fire, Swampfox will repair or replace it promptly. That’s our code. That’s our word.

RETICLE
Swampfox Sentinel features a 3 MOA red dot reticle powered by a high efficiency emitter. Switching your sight picture from blocky iron sights to a 3 MOA dot equivalent to just 3 inches at 100 yards provides a much more precise point of aim, resulting in a very real accuracy bonus even with subcompact pistols.

VITAL STATS
Sentinel 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.
THE ADVANTAGE OF TARGET FOCUSED SIGHTING
Micro compact sized concealed carry pistols are notoriously difficult to shoot accurately due to their extremely short sight radius. Having to focus on the front sight to assure an accurate shot in a defensive shooting situation is an additional burden.
Sentinel’s 3 MOA dot is focused at infinity so you can forget about focusing on the gun entirely, and focus on the threat, which is what you’ll be inclined to do anyway. With a sharp crisp dot superimposed on the target, you can make a wiser decision about whether to fire and make those critically important shots more accurate as well.

Sentinel A
Awesome little red dot, mounted right up to my P365xl like it was made for it. The labeled mounting screws for the different pistols and the rubber cover are nice extra touches. I was waiting on the vaporware Holosun 407k but this little sight is a keeper. The always on, auto brightness works like a charm and even when trying to trip it up i.e. dark room to bright outdoors it always seems to be just right. No buttons, no fiddling and no problem. Thanks SF

Sentinel
Just got back from the range with my newly mounted Sentinel on my PCR. Easy to zero, held zero after 200rds, auto brightness worked flawlessly. My PCR was milled by Cajun Gun Works for a Shield rmsc. The Sentinel fit perfectly.

Sentinel automatic
I just received my sentinel, and installed it on my p365. So far all I can say is WOW! it is very obvious a lot of time thought and effort when into this optic. The attention to detail on the entire site, and heck even the way it was packaged is second to none. It honestly makes my shield RMSc look like something I would buy off of wish haha! I haven’t shot with it yet but will update this when I do. So far you can’t go wrong purchasing this optic! Not to mention customer service is absolutely phenomenal. Thanks swampfox!
