Swampfox’s Sentinel II is a straight-forward reflex sight built on the RMSc footprint, which is very common on today’s small guns. Its three m.o.a. dot is available in red or green, and it has a generous 20mm window. It’s built of 7075-T6 aluminum, with anti-glare serrations on the hood.
The Sentinel II has 10 brightness settings, which are controlled manually. Press the up arrow button on the left to increase intensity and the down arrow on the right to decrease it—which I prefer over having both buttons on the same side.

It features shake-awake, which puts the sight asleep after four minutes of motionlessness. This feature can’t be deactivated, so you don’t have to fret about what mode it’s in. The dot automatically comes on at its last setting.
The Sentinel II comes with a unique rear sight guide that screws into the front of the sight body and acts as a backup rear sight should the CR2032 battery fail. This guide is available in plain black, or like the sample they sent me, one with two tritium dots.

Scott Rupp) The guide sits much higher in relation to the bore than standard irons do, and without a correspondingly higher front sight, you’re going to have to account for that. With the Taurus GX4 I tested it on, point of impact was three inches high at three yards and six inches high at six yards.

The sight has to be removed to change the battery, which means you’ll have to reconfirm zero. The dot is adjustable for windage and elevation, and the adjusters have tiny slots, so you’ll want to hang onto the supplied tool.
The Sentinel II comes with four nicely labeled sets of screws and a handy tool for them. Last but not least, you get a waterproof plate that fits under the sight body.
Simple is good in my book. At $269—$299 if you opt for the tritium rear sight guide—the Sentinel II is a well-designed red dot that gives you solid basic features, plus that rear sight guide.
