Micro Reflex Red Dot

Sentinel II

$266.05

Crafted for precision and built to stand guard, Sentinel II showcases a fusion of advanced features in a sleek, cohesive design. Designed for concealed carry, this micro pistol dot sight maintains the standardized RMSc footprint and its familiar slimline profile while maximizing visibility with a larger 20mm window. Its most unique feature is the patented removable rear sight guide installed in front of the window. This guide provides backup support for micro pistols that sacrifice their rear iron sights for dot sight compatibility. Sentinel II displays a 3 MOA dot in either red or green illumination and is equipped with Swampfox’s Shake 'N Wake auto on/off feature for grab-and-go readiness.

STAND GUARD

Sentinel II is a rugged micro dot sight designed for everyday carry. Combining manufacturing experience and consumer feedback, we’ve made great improvements to design an optimized compact optic solution. The RMSc footprint provides compatibility for most optics-ready slimline pistols while its recessed hood design and shielding lens coatings protect its larger viewing window. Sentinel II stands as the latest advancement in Swampfox micro red dots.

STAND GUARD

BIG WINDOW, SMALL FOOTPRINT

Despite its slim RMSc mounting footprint, Sentinel II maximizes visibility for quick target acquisition with a new 20mm objective window – an improvement over the 16mm lens of the first generation optic. Fully multi-coated to resist scratches, fog, and water, and protected from glare by rear hood serrations, experience improved clarity no matter the shooting conditions.

BIG WINDOW, SMALL FOOTPRINT

GUIDED PRECISION

Sentinel II is uniquely equipped with patented removable rear sight guides from Night Fision. Installed forward of the optic window with titanium screws, the hardened steel and black nitrided precision guides not only act as an alignment tool but also as a distinct landmark for those familiar with traditional iron sights. For shooters desiring more, pair the guides with a matching height yellow jacket tritium front sight, coming soon for Glock, SIG Sauer, and Smith & Wesson M&P Shield subcompact handguns.

GUIDED PRECISION

ILLUMINATION AT THE READY

Featuring a crisp 3 MOA dot in either red or green and 10 manual illumination settings, Sentinel II stays at the ready longer with a bottom-mounted CR2032 battery and Shake 'N Wake auto on/off. Brightness settings 1 and 2 are night vision-compatible with settings 3 to 8 for low-light and indoor applications, leaving settings 9 and 10 ideal for daylight shooting.

ACCURATE ADJUSTMENTS

Sentinel II provides 80 MOA of adjustment range for both windage and elevation. With adjustments of 1 MOA per click, users are well equipped to fine-tune their aim for targeting at any range. With tactile click adjustments, the zeroing process is easier even when wearing hearing protection.

ACCURATE ADJUSTMENTS

BUILT FOR THE FIGHT

Manufactured from tough 7075-T6 aluminum, Sentinel II offers improved durability over its previous generation. A new body design better protects the LED emitter from the elements and provides enhanced protection for its recessed lens against surface racking. Armed with robust design features and optional add-on Ironsides Shield, Sentinel II is capable of withstanding everyday use and abuse.

  • I'm a Fan: So far so good, this is my first Swampfox product and I really like the quality and value so far. I put the Sentinel II on a Walther P99 with EGW dovetail mount - It works great. I really like the complete kit of parts included, like all the screws in neatly labeled bags, the mounting plate shims, etc. I've only put in about 50 rounds with my Sentinel II so far, but it's nice. I do wish it could go a click or two brighter, that's one of my own desires on the Trijicon SRO as well and some other dots, but for some reason my RomeoZero (which just starting losing it's zero) is notably brighter than the Swampfox in it's top setting, but I think I will get used to it. I would buy Swampfox again no doubt.

  • Very Nice !! I like it better than the earlier model.

  • First and foremost, Swampfox customer service is absolutely great!!! This is my 1st Reddot so nothing to compare to. However, the look, feel, and install was flawless. The multi-pack of screws provided the perfect screws for my S&W 9 EQ. The sight-in was very easy. The quick adjustability of the Reddot, the size, and clarity of the glass makes getting on target very fast

  • I got the Sentinel 2 after my Sentinel 1 had a part fall off and they didn't have anymore. I have to say I was blown away by the customer service I received. Top notch guys. The Sentinel 2 Green Dot I got is a clear crisp picture. They give you screws to mount it on just about any gun. Even at the lowest brightness setting, I can pick it up in the sunniest of days and full brightness is just a robust clear crisp dot. I recommend this optic and the Justice which I have now but if I get a new pistol that's optics ready I will get the Justice 2.
