The Primary Arms Gen III 3X Compact Prism Scope with the improved ACSS-5.56-CQB-M2 reticle is the lightweight, do-everything scope you've been looking for. 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 Gen III scope has been equipped with the next generation ruggedized mounts to provide flexible mounting options with incredible clamping power.

  • Fully illuminated reticle is visible even in bright daylight
  • Removable M1913 picatinny top rail for accessories or piggy-backed red dot sights

The heart of the 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 the 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 the 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.

Very Impressive

Super happy with this scope. Right out of the box it was basically zeroed. I could probably adjust it a click or so in each direction but it's pretty darn close. I've probably tested more optics than I should have and this one is up at the top with some of the best I've used. I'll also be picking up the 5x model based on the performance of this 3x.

A touch strong for indoors but quick pickup

by -

The scope is a nice setup. I think it's funny that the 3x version has the more detailed BDC Christmas tree compared to the 5x. That lacks the utility it could have if paired with the higher power.
<br>This optic is a touch strong for clearing rooms and indoors and will give you a bit of edge distortion and will be slightly slower. But this is a prism not a red dot so you picked this.
<br>Shines from about 10 yards out in speed and precision. So it's an amazing optic on my 10.5" if slightly clunky indoors.

Love the optic works wonderfully

Perfect optic for short-mid range

by -

This optic is ideal for reaching out to 300 & 500 yards while still keeping both eyes open and transition to cqb ranges. Acss make range finding simple and fast.

This scope is awesome!


From placing my order to my door in NC in 4 days. Mounted and ready to go. The clarity of the glass and reticle are just incredible. Heading to the range tomorrow.
<br>Primary Arms never lets me down.

I am using this on a Riley Defense AK-74. It is a perfect match.

5.45x39 good

by -

Put this on my AK-74, glass is clear, the caps are quick to open, like that i could remove the 1/3 block between optic and base, was easy to zero. Fits my needs perfectly

My first prism scope


The unit is robust & capable. I did have one issue within the first 200rnds of the mount loosening up, could have been user error. No such issue since. I have better then average eye sight and my only regret is getting the 3 power rather then 5 power. Rectical is tiny. Works great.

the one star review on this scope is a joke!


the idiot cant figure out that the elevation nobs are just caps that hide the actual nobs that click lol
<br>AMAZING scope for the cash BTW! ill def buy again after getting mine

Great bang for the buck

This is my first prismatic optic and I am very pleased. I would give 4.5 stars if possible.
<br>The reticle is excellent and intuitive. I was initially concerned about it but found it to be very intuitive after short order. Sighted in quickly and easily. Adjustments were crisp and precise. Was ringing 8” gong out to about 100m in short order.
<br>Illumination was plenty for a bright summer morning. The reticle is clear and crisp even with Illum on all but the highest settings. Some bleed at the highest settings.
<br>The Only negative is not really the optic, but I want to mention it for others in case this is their fist magnified prismatic. I find it nigh impossible to shoot both eyes open with it as I am used to with non magnified optics. I don’t have enough time with it yet to see if that can be resolved with time.
