Primary Arms SLX Rotary Knob 25mm Microdot with ACSS Red Dot Reticle

I was in the market for a sight for my airsoft rifle and found this for a little over 100 which isn't a lot more than the airsoft sights I was looking at, which had questionable reviews and I figured why not spend a little more for something that could be used on a real firearm if I decide to move it. It came with 2 mounts and a couple spacers to allow for more options, it seems the highest it goes is a 1/3 co-witness height which works for me. This sight has pretty clear glass from what I can tell, although it does seem to have a slight bluish tint but its not too distracting. The actual reticle is pretty crisp, I do have astigmatism so I don't see it quite as its designed ( the chevron looks more like a fine dot), but under the right lighting it looks as it should. Cant really speak on the battery life as I just turn it off after a game. I highly recommend this sight as a higher quality option for airsofters or for your real firearms as well.

I tried a cheaper reflex that didn't really perform so I bought this to replace it. It seems well built and sturdy. The range of lighting should work for any situation. I used it in daylight and there were even higher brightness settings available. The brightness can also be dimmed below the visible threshold for night vision but I can't test that. There were no issues with parallax at either 50 or 100 yards. I can't really think of anything that would make this sight any better. The group I shot at 100 yards was as good as I am ever going to shoot without magnification.

I don't usually leave feedback unless I feel that my observation can be useful to others. This is the case with this optic. I generally use Eotech's or Viper PST optics. However, I wanted a slightly cheaper optic that would perform and function flawlessly and be reliable and robust enough to be used in any kind of scenario. I was super impressed from start. The reticle is similar to the one on PST and it is easy to use sight in. As someone else stated the optic only needed a couple clicks up, and it was on. I did not have to adjust left or right. The glass is clear and brightness levels work for most environments. For the price, this optic is a steal and I would buy another in a heartbeat. It has so far stayed zero and functioned perfectly. It's a great alternative to a higher price optic with the same features. I highly recommend it and I was paid or rewarded for my review.

I own several other high end red dots and this one is almost as good , I say this because the others are shake to wake and auto shutoff , besides that these are nice for being much cheaper

Absolutely love this optic! The acss reticle is fantastic! Glass is clear. Solid build and daylight bright on highest setting! Way above price point in my opinion. Pairs great with my tacticon 3x magnifier! Very happy with both!

This optic is bright , crisp , and holds its Zero. Three round groupings at 40 Yards inside of a bottle cap in Size. Wide Field Of view and if you are using it correctly with both eyes open you can very quickly acquire close and distant targets. The Chevron make windage easily calculatable to ensure confidence in fast decisions and quick acquisition of Targets. Two thumbs up. My Buddy rocks a SIg Romeo 5 Red dot and prefers my MD25 from Primary Arms. Only Down fall it this is not shake to wake, but at the same time neither was my M-68 on my Combat A4-M16. I can easily turn it off and on when necessary. I hope this help in your decision making. With lots of red dot experience this is the best bang for your buck by a mile :) Good Day and GOD BLESS AMERICA

Most red dots in this class have battery life ratings of 30-50 thousand hours. This one is rated for 12,00 - and I think that's a very generous overstatement. When I store this optic, I keep it turned off since it doesn't have a shake-awake feature like many others do. Even still, running home defense duty and maybe 4 range trips since I purchased it, I've had to replace the battery three times, one of which only lasted a month. The coin slot used to tighten the battery door is also easy to strip out, which makes changing the battery difficult. I'm pretty disappointed with this product and would advise you spend your money on a different optic if this is going on something other than a plinking gun.It's a dang shame, too, because I really like the reticle and nobody other than Primary Arms offers it.

I really like this optic. It is everything that I needed without all of the (mostly annoying) extra stuff. The mount is over engineered, almost to the point of absurdity, and seems excessively sturdy. The large window is really nice especially with the acss reticle. The reticle is kinda small and hard to see the drop dots without magnification but it’s easier to pick up than a plain dot. The only complaint I have is there’s a slight blue tint to the glass which helps with the reticle clarity. It’s not extreme like the sunglasses glass on some red dots out here, but it’s noticeable.
