I love it. - OpticsPlanet Exclusive Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

Mounted to a G43X MOS. Installation was easy and quick. I have the always on/auto brightness model. It includes all the tools you need to install it. I did use my own torque driver to secure the bolts. The auto brightness adjustment is very nice. The dot is clear and crisp. I added co-witness height sights. There is no cut out to allow you to see your stock iron sights, if the optic fails. Zeroing was quick and easy. Mine required no windage adjustments, just some elevation. I’ve put approximately 600 rounds through it, with no change in the zero.

Target acquisition is fast, like most dot optics. Since it’s low profile it takes a little more practice getting your eyes lined up through the window onto the dot, but like any sighting system it takes a little practice.

In all, I’ve been very pleased. This is on a EDC weapon and it added very little bulk and it’s super light, so you don’t notice any change at all in overall weight. Durability seems good. I’ve had no issues with damage or the zero being affected by general banging around associated with EDC. I’ve even dropped it onto the ground from about waist height, with no issues. This was accidental when it fell out if a range bag.

My only issues are:
1. The optic must be removed to change the battery. Due to its compact size and low profile, it’s probably difficult to build it with a battery compartment on the side, etc. Ive had mine set up since July of 2021 and the power is going strong on the original battery, so it’s not like I’m unmounting it every few weeks to change it out.

2. There is not cut out to allow you to see your iron sights if needed. Not everyone will have an issue with this, but when using optics on any weapon, I want iron sight capability just in case. For close range engagements, you could still make hits on bad guys if you are comfortable with the weapon and you practice regularly. I just prefer the option.
