The SLx optics are the heart of the lineup. The trusted optics that have built the reputation through the years. Although many SLx optics will be familiar to Primary Arms fans, they are always pushing forward with new generations and adding even more options in response to the demands of the loyal customers.

The full size 30mm red dot is back and better than ever! The Primary Arms SLxZ is the flat dark earth coated Advanced Full Size 30mm Red Dot with an estimated 14,000 hours of battery life, three night-vision compatible brightness settings, a lifetime warranty, and much more. The true 1x field of view and crisp 2 MOA dot combine for an unbeatably quick and precise sight picture while shooting with both eyes open. This red dot is protected by the Primary Arms Limited Lifetime Warranty. If a defect due to materials or workmanship, or even normal wear and tear, has caused your product to malfunction, Primary Arms will either repair or replace your product.


  • True 1x field of view
  • Flat dark earth anodized finish
  • 30mm tube diameter
  • 2 MOA red dot
  • 10 brightness settings
  • Includes battery
  • Lifetime warranty

The first three brightness settings out of ten are night vision compatible and can only be seen when the red dot is used together with a separate night vision device. Turning the rotary switch until it stops in either direction will turn the red dot completely off. At the highest settings the 2 MOA dot is instantly acquired by the eye even in bright daylight. The 30mm Advanced Red Dot uses the latest LED technology to display a dot that is a deeper red in color, and appears more sharply as a perfect 2 MOA circle.

The one-piece main body is stronger and lighter than previous full size red dots. It is compatible with any industry standard 30mm type red dot mount and will give the stated co-witness of those mounts. The Primary Arms High Cantilever mount (PAHICANT) is a great choice for a solid basic mount on AR-15s and many other rifles. This optic is powered from the factory by a single 1/3N “button” battery, but in a pinch you can substitute two LR44 batteries in the same battery compartment.

30 MM Red Dot

by -

Put this red dot on my 458 Socom, after 100 rounds I love this optic. Did have to crank down the mount to rail screw, 458 has a little recoil. Thos is a true 2 moa dot and crystal clear.

Excellent Red Dot

Holding zero with 458!
<br>Dot is clear
<br>Same as other review. Go a little heavy when turning those mount screw or it will move around when you're tossing slugs that heavy

The finish seems very nice, almost identical to Magpul FDE, maybe just a bit darker. The adjustments for illumination are solid and don't feel mushy like some other cheaper red dots I've used. The rubber cap retainer works great and is not hard to get on. The flip caps that come with it seem cheap but I ordered some clear Aimpoint ones to replace them. All in all I'm very pleased.

Money well spent

Wow, alrighty guys I've owned Vortex and Sig red dots and this thing is just unreal. Selection is crisp and can go either way. The glass is absolutely brilliant and the dot itself is extremely visible even with a 400 lumen light shining on a white wall. Excellent dot for the price.

Great inexpensive red dot

I bought this for my AR 15 300aac pistol build. I did a preliminary 10 yard laser sighting and fine tuned it at 100 yards. It is beautiful. I'm hitting 2" groups at 100 yards. For a 10.5" barrel I thought that was pretty good. I love Primary Arms...Thank you so much.

Clear dot and glass

by -

Nice red dot sight. Glass is clear as day. A must buy

Great sight

by -

This sight has a lot of features to include night vision compatible. The order was filled quickly. The sight was easy to mount with the cantilever mount. Very easy to pickup the red dot when getting on target. This sight compares favorably with the Aimpoint I used in Iraq. This is a great piece of equipment for those on a budget.

good product for a good price

by -

not a single complaint!

Awesome Dot

by -

The color looks good, the dials are robust with good feedback, holds zero, quick on target. I'd buy over and over.

Amazing Sight For The Price!!


This sight is great and got mine at around 30 bucks! Mounted it on my HiPoint 45 Carbine that late last year I got the Bullpup stock kit in FDE!!
