Exceeded my expectations in every way.

Ex competitive shooter. I’ve has lots of Aimpoints, etc. over the years, but rarely on handguns. Got one of these to put on my Ruger 22/45 MK III, as an inexpensive way to see how a dot might work on handguns before spending more money on a reflex sight and mount. Getting older and my eyes really struggle with focusing on the front sight through my bifocals.
This sight allows me to shoot with both eyes open, wearing street glasses, with my focus on the target. The resulting functional accuracy improvements are impressive.
For less than $100 this is a high quality sight that I would not be ashamed of. Easy to use, plenty of brightness settings (3 or 4 works fine for an indoor range), no eye relief issues, seems to be holding its zero well. Quality is better than its price point would suggest. Certainly not as small and unobtrusive as the current crop of RMRs, but a lot smaller than my 20 year old Aimpoints! Little things, like the rubber bikini cover and thread locking juice that’s included, are a plus. For those using the included picatinny mount, be sure to remove the screws and put Loc-Tite on them before you mount it.
My only really minor disappointment thus far is that the control knob is not bi-directional – from the OFF (0) position, you cannot rotate it clockwise to go directly to the higher brightness settings.
Overall, I am quite pleased with this little beauty. Buy it – Buy it now.

this sight feels well built
the brightness adjustments have nice little clicks for each setting
it appears to have 3 settings for NV
it feels and functions like a quality product
the reason i dont like it? is there are better optics that do the same for less money.
the Bushnell TRS-25 does everything this sight does, and some things it does even better.
first i will say this, i cant tell a difference between this sights 2moa and Bushnell 3moa.
this sight boasts 1,000 hours of battery life, the Bushnell advertises 3x that
this sight costs more than the Bushnell and doesn’t co-witness as well as the Bushnell.
for the price i payed for this sight, i could have gotten the TRS-25 and a medium riser, or the TRS-25 that comes with its own high riser.
because this sight has changeable plated like the aimpoint, its always gonna sit a little higher, unless you purchase a riser made for it to screw into.
im not trying to come off as a Bushnell fanboy here, i haven’t ever tried their scopes and their barrel bore sighter sucked big time, i just constantly hunt deals, cause i’m not rich enough to buy the really nice optics that cost as much as guns lol.
my biggest problem is this….to me this red dot seems to have the same size dot as my TRS, it has similar build quality and boasts, it costs more, it has a shorter battery life, and it needs more expensive specialty risers to co-witness as well as the TRS.
I guess the NV option is cool, but if you have the money for NVG or a NV monocle, youre probably not going to break the bank buying an eotech or aimpoint.
its hard for me to personally recommend this sight over the TRS, considering that for the same price you’ll spend on this, you can get the TRS, some extra batteries and a medium riser.

I know it isn’t an Aimpoint or EOTech, but Primary Arms red dots are the best budget minded red dots out there in my opinion. This is my second Primary Arms and I highly recommend them. I’ve tried others that were cheaper and Primary Arms beats them every time. I’ve had one on my AR15 for years and it holds zero and works well to this day. I got this to mount on my 308 AR for when I don’t use the scope. I’ve tried a couple of other brands on some of my plinking guns that were slightly cheaper but none performed as well as the Primary Arms. I’m in the process of slowly replacing those with Primary Arms. The dot is crisp and one of the smallest out there and the sight holds up well. I highly recommend these.

Update (Original review below): After using it with the .22, I have to say this is a great little sight, and I’m changing my rating from 4 to 5 stars… It’s very effective, and I also take back some of my original complaints. First, upon closer inspection, the brightness knob isn’t plastic, though it feels a bit plasticky (mushy?) as you turn it. The clicks are defined enough to work. Also, outside in the light, the brightness levels were fine. A new minor complaint I found is that the windage and elevation knobs don’t have well defined clicks at all (making the action of the brightness knob seem mechanically precise by comparison), but it doesn’t really matter.
—————–
These are my initial impressions… I will update once I’ve used it some. I got this to use on a .22 Marlin rifle to protect my chickens from predators. For comparison, I have an Aimpoint Pro on my self-defense rifle. The Aimpoint is built like a tank, has a battery life of years while left on and ready to go at all times, and I have absolute confidence in it. But it is heavier and costs 4X what this small sight does. For this particular usage on the .22, I didn’t want to spend much and was willing to have to turn it on and off in exchange for low weight and a much cheaper price. So I thought I’d try the Primary Arms micro red dot.
Pros:
– Cost
– Dot looks fine on mine, crisp with no blur or comma or anything like some have experienced.
– I was concerned about emitter blocking view, and it does block a small amount, but is not really noticeable in actual usage.
– Seems well made and sturdy, except for brightness knob.
Cons:
– Brightness selector knob is plastic and doesn’t give well-defined clicks. It works, but feels fragile and cheap.
– Brightness levels are not ideal. The first few are dim, as you’d expect, but then there’s a big jump at the 3rd or 4th level to too bright. So the level I’m looking for under some lighting conditions isn’t there. Not a huge problem, but it would have been nice if there was a more gradual increase in brightness of each click.
– You have to remember to turn it on and off to preserve battery rather than leave it on all the time, but you’re also paying a lot less.
Yes, it would be nice to have 50,000 hours of battery life while leaving the dot on all the time like with the new model (and for a self-defense application I would require that). But this one is half the price and has a knob for adjusting brightness (instead of push-buttons which I’m leery of). For my particular application this one seems a good balance between price, quality, and capability.

Mounted it at a 45-degree offset, and it’s perfect.
Elijah (verified owner) –
The sight is low-profile and doesn’t obstruct my view.
Paul (verified owner) –
Very impressed with the durability. Dropped it, and it still holds zero.
