The low 3X magnification and bright illuminated reticle allow for fast, both-eyes-open shooting at close range, while the ACSS CQB reticle allows for easy hits on targets out to an impressive 600 yards.

The heart of our tough Gen III 3X Prism Scope is the improved ACSS 5.56 CQB-M2 reticle that combines ranging, wind leads, moving target leads, and ballistic drop compensation out to 600 yards. The outer horseshoe of the glass etched reticle is used for close quarters engagement, simply place the generous semi-circle on the target and run with it! Each side of the horseshoe also has our integrated ranging system. Place the bottom of the target on the bottom rung and range up. If you know your targets are roughly 18 inches wide, they can be ranged on the side Auto Range system, or directly on the BDC hold overs! Two dots on either side of the precision chevron offer a moving target lead moving with an average speed of 8.6 MPH. Each step of the BDC system includes a 5 MPH wind hold, drastically improving first hit probability at any range. As an added bonus, the glass etched reticle does not require batteries or illumination, but 11 brightness settings (including daylight bright) allow for fast acquisition in close quarters, or enhanced visibility in fading light, powered by a common CR2032 battery!

The SLx 3X Gen III has even greater strength and flexibility than ever before with our next generation ruggedized mounting system. We’ve upgraded everything about the mount from materials and finish to the design to create a mount that will not just clamp securely to your rail, but stand up the rigors of real-world use. Integrated recoil lugs help lock your mount in place against the heaviest recoil while large diameter crossbolts give you significantly improved clamping power and will hold up to significant torque. The included riser is the perfect height for AR-15s and AR-10s, but can be easily removed for carry handle or AK use as well.

Great for people with crummy eyes


I have a super bad astigmatism and I've have had problems with sights not being crisp and clear. I'm going to start selling all of my other ones like my strikefires and purchasing these. This optic is amazing!

Excellent optic


This is a good optic with an amazing reticle. I’ve had everything from vortex to trijicon to elcan and this reticle beats them all. Dollar for dollar you won’t find a better fix power and variable power scope than Primary Arms.

Great scope and reticle


This scope is great, especially for being under $300! I put it on my first AR (5.56) and had it zeroed at 100yd with 4 shots. After that, I was hitting steel targets up too 500 yd on the first shot using the reticle, and so did my friend who wanted to try it out. It’s also a solid build, especially on an aftermarket QD mount.
<br>The only downside for me was that I couldn’t mount my MBUS behind it due to the eye relief, but that isn’t a big deal since the scope works with or without batteries. I just store the back up sights on the front of the receiver and I can put it back on if necessary.
<br>Also great for anyone with astigmatism. I need a prism scope for this reason and the reticle is crystal clear. Of all the names in this price range, this is the best choice, especially with the reticle.

Highly recommended


The glass quality is excellent, the ACSS reticle is practical and uncluttered, turret adjustments are crisp and tactile, the illumination is truly daylight bright, and the unit seems very robust overall. As with all prism optics, the eye relief is a bit limited, especially if you run an AR with a fixed or fully extended stock and you don't shoot with your nose close to the charging handle. If you fall into that category, I highly recommend looking into the LaRue LT681 to bring the optic further back than the factory mount will allow. A fantastic optic at this price point.

This is an absolutely amazing optic. Installed it on a ruger ar-556 pistol with 10.5" barrel. Right out of the box it just exudes quality. Installation was a breeze, sighting it in took about 5 clicks, then...I was tagging a steel target at 200yds on a hill with absolute ease.
<br>The reticle. I was on the fence about this optic as some reviews I read stated the illumination was a little dim. If you are aiming directly into the sun, yes, you will have difficulty seeing anything. I had zero issue with using this optic with the illumination shut off. I have tested it running through the house at night on a setting of 5 and it is crisp, clear and really easy on the eyes.
<br>I highly recommend this optic. I have shown it to a few people who instantly asked where I got it and how much lol I don't think you could go wrong with this optic and I give it my wholehearted approval. Just sucks that ammo prices has shot through the roof :)

Working man's optic


Gets it done for the price. Not everyone can afford to dump $1000+ on an ACOG, Razor, or Atacr but this optic is reasonable enough that an average guy with an average paycheck can buy it without breaking the bank. Its a bit on the heavy end for what it is but the 3x magnification is crystal clear even with my 20/70 right eye with astigmatism (without glasses!). Plus 3x can still be used with both eyes open at close range if you put in the time dry-firing with it and getting used to it.



I have acog Ta31 and this optic. The 3x is my favorite optic to have on my rifle! Primary arms make absolutely great optics.

Spectacular performance for entry level price


Terrific for people with bad eyes was shooting amazing groups with my smith and wesson mp15

Excellent Scope, Amazing Value, Beautiful Build, No Brainer


I bought this scope after extensive research, as my budget would not allow for a Trijicon ACOG, which was my first choice. WOW. Glad I saved my money and went with SLX. Simply amazing scope for the money. Crystal clear glass, solidly built like a tank, excellent "Cerekote" like finish, easy to zero with audibly tactile 1/4 MOA click adjustments for windage/elevation, and the ACSS reticle, which alone is purpose enough to buy this scope. I also have very bad astigmatism, and the reticle is crystal clear with no fuzziness, thanks to the easy focal point and brightness adjustments. I was able to place it in front of my Magpul flip-up sights with no focal point issues. In my opinion, this scope is just as well made, designed, and built better than most scopes that are triple the price. At the range, out of the box, shot 2" MAO groups at 25 yards, and 1" MAO groups at 10 yards for CQB without zeroing. Once zeroed, shot sub MOA groups from 10 to 50 yards using PMC 62 grain 5.56 green tips.
