Primary Arms SLx MD-25 Rotary Knob 25mm Microdot - 2 MOA Red Dot - Red Dot Bright™

I'll start by saying this is the first time I've been disappointed by a product that primary arms offers. That being said, I'm highly disappointed in this item. Even in a walk in closet with no lights on pitch black darkness the n1 and n2 settings give no dot at all. It only works on settings 3 and higher. Even at that from settings 3 to 6 the dot is nearly impossible to see unless you are in complete darkness. From settings 7 to 11 even under bright light the dot burst progressively worse. Setting 11 burst out so terribly bad that even under the brightest shop lighting I have it makes your sight picture unseeable. The frustration and time it would take me to send this back and get another one simply isn't worth it either, seeing that it took two weeks to get to me the first time. I'll probably still buy other products from primary arms but after this I highly doubt I'll ever buy any kind of optic here again.

I received my new red dot fast and in nice packaging in good shape and was really happy with it. Then I noticed the front lens was angled at maybe 25ﾟ. In true rookie fashion I thought "this doesn't seem right I'd better return this". As it turns out, all red dots are this way. It's crooked because the laser is on the side and it focuses on the middle so to get into your eye in the center it has to be canted. In the end, customer service was really helpful, they returned the red dot back to me in fantastic condition, and I feel stupid and wanted to make sure everyone else knew that it was supposed to be that way. They said it happens all the time, and they weren't sure how to make sure everyone knew. So I'm doing my part.

Quality is almost consistent among the 4 sights I purchased in the last two months with only very slight bloom on one more than another, I personally feel you’re getting about $200 dollars worth of product for way less.

Nice quality glass, rugged construction, great base options included in the box, really nice finish. I mounted it as an absolute co-witness on a BCM upper and as expected, my astigmatism caused it to flare BUT then flipped up the rear sight and the flare disappeared….

First, I own about 30 red dots ranging from $30-$150, I am always looking for best value and purpose of use. I received my MD-25 and was nothing short of shocked at how well it is made. It makes much more expensive optics feel like toys. Glass good to great, 30mm instead of 20mm that are usually in this price range, priceless. For Lefties, the knob being on the right side is perfect for us. Will buy again, very happy.

I like this red dot a lot it keeps the ar's weight down , comparing it to my aimpoint pro it's lighter smaller and looks like a quality optic the clarity's not quite the same but it will work for me just fine . I put it on a ar that , I wanted to keep the weight and cost down but still have a dependable rifle I have accomplished that I would recommend to friends the downsides mention by some of the adjustment dial being too stiff is warranted but mine seems to being a little less stiff after about three or four turns on the dial it will probably be fine after a while the knob does cut down on my vision being on the left as stated by some probably will not get used to it but if your left handed it would be great for you . I like it more than I thought I would if I had substantial money to spend I would buy a aimpoint t2 but this is less than I allotted for the optic and am totally satisfied.

Had to replace a Sparc II on a firearm. This is a great sight, it might even be better than the Vortex Sparc it replaced.

A great DOT. Mounted on a Clark barreled S&W Model 41. Way more accurate than I am.
Only negative was the low profile mount included did not match rail. Lug spacing was off a little.
Took a file and slowly knocked a little off until it had a gunsmith fit. Was like filling a match barrel to a 1911.almost tight enough it will stay on without tightening.

These are great little sites. Easy to use easy to set up highly visible. I got the IR honeycomb filter in bikinis. Awesome sites recommend you buy several of them.

This red dot is the best for the money. It’s clear and continues to hold zero after hundreds of rounds have been fired. It comes with a lot of different mounting hardware for multiple height configurations. My only complaint is it doesn’t come with caps. Butler Creek Blizzard series flip up scope caps work perfectly. The Blizzard series are see through so you can see your dot with them closed. Some of the other comments in these reviews are not right as far as what size caps to order. You’ll need two different sizes as one opening on the red dot is slightly smaller than the other one. I chose the Butler Creek Blizzard series size 1 and size 2. They’re about 10-15 dollars a piece. Size 2 was hard to find but eBay had them.
