what else is there?
Let's check out more...
The Swampfox Sentinel has a very similar window size as the Holosun 507K and Trijicon RMRcc.
The window size is: 16mm wide, 16mm tall
Here is the deal: The optic might be slim, but it doesn't seem like the window is any much smaller than other full size optic.
Lens tint is there, but it's not noticeable at all.
Another thing we love on the photosensitive model is that there isn't any glare reflection from the emitter, so the sight picture is as clean as what you see in these images
The Swampfox Sentinel features a 3 MOA single dot reticle. It's the middle ground between a tiny 1 MOA dot and a 6 MOA dot.
When I mounted this on the Springfield Hellcat, I was able to pick up the dot fairly fast and as long as I keep a good grip and presentation the best I can.
During live fire drills, the muzzle flip will throw the reticle off center, and it takes time to get it back. It is what it is even with a large window optic like the Trijicon SRO.
If you have trouble finding the dot, we got couple unobvious tips you can check out here.
It takes a CR2032 battery to power the sight, and it lasts about 2 years based on manufacturer's specs. We will test it and update this content.
This is the photosensitive optic model, and the sensor is located on the side of the optic and it controls the reticle brightness.
The photosensitive model works well during the day, but it doesn't work well in low light situations unless weapon light is turned on.

It's plenty of battery juice to last almost 2 years before consider changing it, but we highly recommend you to replace the battery every year just to top it off.
The body is made of 7075 T6 aluminum, the highest grade material for field grade optic up to date. As far as running this optic hard, we will update this content to show you these following tests:
- Repeated recoil to hold zero
- Slide racking
- Every day carry wears and tears
1 MOA / Click is all you get with this optic. It provides plenty of adjustment for what it is designed for - CQB
The elevation and windage adjustment knobs are recessed to prevent accidental adjustment.
However, the only downside is that there is no positive / audible feedback when dialing the turrets, and it requires a small flat head screw driver to adjust the screws.
Sentinel features the Shield RMSc footprint, so it will fit directly with optic ready Sig P365, Springfield Hellcat and Glock 43.
Use For Conceal Carry
Is the optic small enough for conceal carry?
The optic is slim on a subcompact handgun for conceal carry and there is no doubt about that.
However, the only downside of an open reflex sight is that stuff, dirt, hair and other things can fall into the opening while holster under your cloth even if you're a super clean person.
Overtime, things can build up without cleaning, can affect dot clarity or potentially block the emitter.
As far as being slim for conceal carry, this gets a 10/10 score!
Final Verdict - To Buy or Not Buy?
It's built tough, the lens is clear, the dot is clean, and it fits on already RMSc footprinted gun slides without additional modification.
