Reviews & Ratings for Primary Arms SLx MD-25 Rotary Knob 25mm Microdot Red Dot Sight — 22 reviews — Page 1

I wish this was shake awake but when you’re on a budget. You get what you pay for.. everything else on this red dot is above average

This is an OK budget optic. It would have been better if it came with lens caps. My big issue with it is that the rotary dial to turn it on and adjust the brightness is VERY hard to turn. I reached out to Primary Arms and was advised that they are very stiff and I should use a rubber glove and sit in front of the tv to break it it. Yeah.... no.
It is a good size, the red dot is crisp and the glass is good. But I've already left a few layers of skin on the darn dial so I can't recomend.

It doesn’t stand out in any particular category but delivers like a red dot priced twice as much. Glass is clear, dot is easily picked up in multiple lighting situations, controls are crisp. Only thing I’d change is an off between every brightness setting. Would buy again for sure though, especially for the money!

An easy to use optic at a great price. Highly recommend for beginners.

Comes pre installed with a battery and roughly centered dot.

Comes with a lot of mounting plates.

Don't forget to buy the kill flash or bikini cover. Those are extra.

This is for my beretta 300 patrol. It is a solid optic have had no problems yet. Good for the money. I would definitely suggest giving it a few runs at the range before using it as a your main home defense optic. I did notice it took my wife a short amount of time to feel comfortable with poa to poi. I’ll probably buy another one for a pcc.

This is my 3rd primary arms red dot, budget friendly Life time warranty and clear, highly recommend better has good life . As far as Optic Planet perfect delivery came on time very good experience with Optic Planet

Fantastic red dot. I wanted a simple 2moa dot for 5.56 pistol. The larger objective lens provides a greater field of view and quicker engagement. Primary Arms optics have been my go to and I have experienced great reliability and solid performance every time.

I would totally recommend this optic it will totally work no doubt for most people the mount works for me and co witnesses with my Midwest fixed sight and with my bravo stock if I lay my cheek light down I looking above the fixed sight aperture firmly down on stock I am co witnessed I would recommend to friends but it's not perfect the dial is stiff but mine is a little nicer after about 3-4 turns of the dial I don't like the dial obscuring my left eye vision but I will live with it I am not going to nitpick for those problems and the stiffness of dial will be fine after a while it taking a common battery that I can find at the grocery store is a plus also if you have lots of cash laying around buy a aimpoint but if your like most people and cost conscience and want a lot for little in a small package buy this it's packaged well by primary arms and optics planet also shipping was fast also I am not a snob so I have to give it a five

In my honest opinion I believe this red dot to be better than a vast majority of bigger name brands on the market. The SLx-25 comes with 3 night vision settings which work flawlessly if that’s your thing, the dial is butter smooth, the adjustment is a solid click for sighting in and the battery life is 50,000 hours…. That’s almost 6 years. I leave mine on 24/7 on a medium daytime bright setting and a good middle ground for at night, so I’m not getting any overflow and it’s never given me any issues. I highly recommend to anyone. Looks and feels amazing when paired up with a Reptilia 1.93 mount for the Aimpoint T1/T2.

Read all the negative reviews and some sound legit but some don't... got mine with a little blue tint on the lens but doesn't affect the performance to me.... i did have to buy lens covers for it as it is not included in the purchase but comes with everything ready to install on any rifle from AR to AK, got mine installed on my MINI 30 and hold Zero very well. Cannot go wrong with the price too....
