Most Helpful Positive Review Best bang for the buck red dot out there
I beat this little thing as hard as I do my Aimpoint T1s and MRO. Sight picture is almost identical to T1micro it’s almost as tough and doesn’t cost much at all. I put this on a budget build for my truck gun. I ran it in a class last weekend for vehicle carbine work and bashed it getting in and out...

Most Helpful Negative Review Poor Quality Control
I submitted a review on the Primary Arms website but they only publish positive reviews. I received two of the Advanced SLX red dots yesterday. Both were defective. Almost half of the sight picture is blurred out with a red haze. This is the case even on the lowest daytime brightness setting. I own ...

A no-frills, basic red dot that works.

by Xcalibur, Verified Owner from MO, United States Written on March 15, 2024
It’s a great red dot that does its job without any extra bells and whistles. I put this on my Krink and it handles 7.62 recoil just fine. If you’re looking for a red dot and don’t need any extra frills, this is definitely a good option.
Best Used for:
  • Rifles and shotguns

Really good read that there’s no job primary arms. It’s a home run.

by Eddy, Verified Owner from ID, United States Written on September 28, 2023
This is my second read that from primary arms he can’t go wrong with her stuff. Whoever is the manufacturer is a great job. The only thing I wish it came with was a riser. It doesn’t call exist with pop-up sites so you need to know that I did, and that is, a really nice read that of course the higher you turn it to fuzzier the Donetsk lower the setting is more clearer on the dock

Tough red dot

by James, from TX, United States Written on April 3, 2023
Bought this for my AK, Fit well on my new mount, looks great and doesn't add much to the weight. Took me a while to get it to zero, but once it got on it stayed there recoil did not seem to effect. it Good for the money. Very happy.

Promise at first but a let down

by Jasper Beach, Verified Owner from MO, United States Written on August 24, 2021
I've had this remote for about 6 months and I believe it has finally died with almost no to very little use do to ammo prices. It slowly was losing brightness thought it was battery 6 batteries latter only works on max brightness everything else nothing. Stay far away and get a good low mounting red dot instead. But once cry once
Pros:
  • Works sometimes
Cons:
  • breaks easily, not worth the money
Best Used for:
  • Looking at turned off
Would recommend: No

Still tickin'

by Thomas, from CO, United States Written on June 29, 2021
While I don't have this particular red dot, I have the Gen 1 Version.
Its seen alot of abuse on my truck gun. Its been frozen, its been hot, its fallen out the back of my truck while moving. It keeps zero just great.
I've been telling myself I'd upgrade to this new one once my old Gen 1 breaks.
I almost did the upgrade when the adjustment tower o-rings crumbled but, found some new rings and its still trucking.

Don't hate on the brand. Buy it and try it. If not, the scope base it comes with will fit on your sons nerf gun. Not Kidding.
Pros:
  • Insanely resilient
Cons:
  • Hard to break ( and justify buying a new one)
Best Used for:
  • Best for guns you're going to drag behind a truck
Would recommend: Yes

Save your money..walk away.

by nick d., Verified Owner from MI, United States Written on March 3, 2021
NOPE! Just walk away. This DOT is nothing I'd take into battle & for that matter wouldn't even TRY training with. Not only does the DOT travel with every movement of your head position, it starbursts.Further, the lense circumference Halo's as a bright red circle. I bought to mount to my AK with Midwest rail and it does NOT allow for use with your OEM sights even on the lowest plate. Yeah, it's an attractive sight! But who cares..it doesn't "work". Save a tad more cash and get a SIG Romeo or a Vortex SPARC2.But this..this is junk and a complete waste of your time, money AND your return for credit.
Pros:
  • Looks cool
Cons:
  • Doesn't function as advertised
Best Used for:
  • Paperweight
Would recommend: No

Perfect little optic!

by Brass Moustache, Verified Owner from WA, United States Written on October 28, 2020
First off, a huge thank you to the Optic Planet's customer serive team for swappibg my order so i could get this little piece of kit asap!
Ok, I absolutely love this little red dot. It's small profile works beautifully on my Kel Tec sub2k, and paired with the M*CARBO flip up optic mount it's dead on target with co-witness! The construction is absolutely solid due to the material and machining involved. The red dot is clear and crisp with a rotary knob that is solid. So happy to have gotten this red dot, so I can chuck the cheap plastic and clunky red dot I was using earlier and use this perfect little optic!

Perfect for survival rifles and shotguns.

by Chazz, Verified Owner from CA, United States Written on June 2, 2020
Have 4 of these and all have performed without problems. Great red-dot for the price.
They are small enough to use on shotguns and survival rifles, for instance, Ruger 10/22 takedown & Ruger PC9 takedown.
The small size makes it easy to fit in backpack while mounted on rifle.
Would recommend: Yes

Good sight at a good price

by Stuart, from MT, United States Written on April 2, 2020
I mounted this on a Ruger 10/22 with a Magpul backpacker stock and mount.
The whole package is very tidy.

I'm a little uncertain about the 2moa dot as I have not had time to do a lot of shooting.
I got the 2 moa for accuracy at distance (lets say up to 100yd on gophers)
Wondering if a 3moa may have been a better compromise for shorter distances.

Zero at 25 yd was simple and straightforward.
Pros:
  • Price
  • Size
Cons:
  • None so far
Best Used for:
  • Accurate controlled shooting
Would recommend: Yes

PA MD-RB-AD red dot good so far

by MG, from CO, United States Written on December 21, 2019
The Primary Arms MD-AD-RB micro red dot works well so far; no immediate issues and the lifetime warranty should cover any which develop over time. The rotary dial seems like a better choice than the push buttons, for electrical durability and winter glove usage.
