After rigorous field testing, this optic has been given a Silver-tier rating by the National Tactical Officers Association.

This Primary Arms rifle scope is part of the SLx optics line. SLx optics have built a reputation for innovation, reliability, and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.

The Primary Arms 1X Compact Prism Scope with ACSS Cyclops reticle combines the durability and flexibility of an etched reticle with the speed and ease of use of a red dot. Unlike most prism optics, the 1X Compact Prism Scope has a generous 3.7 inches of eye relief combined with a massive 13mm exit pupil to provide an exceptionally forgiving eye box. This allows for a high degree of efficiency in red dot-style shooting, keeping both eyes open for fast target acquisition in a variety of positions and circumstances that no other prism scope can touch. The 1X Compact Prism Scope’s included 1913 MIL STD Picatinny rail mount is removable, and the scope body is compatible with industry standard microdot mounts.

Features:
  • Silver-rated by the NTOA!
  • Glass etched reticle that works with illumination on or off
  • Partial reticle illumination with 11 brightness
  • CR2032 battery provides up to 13,000 hours of reticle illumination at medium settings
  • Forgiving eye box with nearly 4” of eye relief, and a bright 13mm exit pupil
  • Patented ACSS Cyclops reticle provides fast target acquisition, range estimation, and moving target leads out to 400 yards.
  • Quick adjust diopter ring for shooter-optimized reticle focus
  • ½ MOA click adjustments with capped turrets
  • Compact design at just 4” long and 9.7 ounces
  • Uses industry standard microdot mounts
  • Wide 76.3-yard field of view at 100 yards
  • Durable design for fog resistant, waterproof, and shock proof operation
  • Black hardcoat anodized finish
  • Protected by a lifetime warranty


At the heart of the 1X Compact Prism Scope is the new etched-glass ACSS Cyclops reticle. A heavy horseshoe makes rapid acquisition and reflex sight style snap shooting a breeze, especially when used in conjunction with the red reticle illumination. When speed is less important, the center chevron tip offers an infinitely precise point of aim that won’t cover the target, allowing for remarkable accuracy at long distances. Snap shots and precise hits aren’t the only tricks up this reticle’s sleeve, either! The edges of the horseshoe double as moving target leads, allowing for improved first shot hit probability on mobile targets. To account for the worst-case scenario, the etched reticle remains visible in black even when the scope loses power. Batteries are only needed for the full reticle illumination, giving you the flexibility of a high-contrast sight picture in the brightest of conditions.

The etched ACSS reticle combined with the fast focus eyepiece make this optic an excellent option for shooters with astigmatism. Red dots simply project an LED beam that reflects off glass back towards the shooter’s eye. The smaller the dot size, the more difficult it can be for the brain to resolve the shape, especially when combined with eye issues. This can lead to shooters perceiving the red dot as starbursts, comet tails, and a host of other distracting or obtrusive shapes depending on the shooter’s eye. Etched reticles and prism scopes don’t have this problem, and by adjusting the fast focus ocular ring, a perfectly crisp view of the reticle can be achieved for anyone. A clear sight picture will lead to more confident hits and better accuracy at further distances than ever before.

The 1X Prism Scope body is just as tough as the rest of the proven line of prism rifle scopes. During durability testing, the 1X Prism Scope outlived not one, but TWO piston-driven .308 Winchester rifles, selected specifically for their reputation for driving optics to failure. Combine that toughness with waterproof construction and nitrogen purging for fog resistance, and the 1X Prism Scope is an optic you can trust whether you’re a weekend plinker, a competitive ace, or a hunter in the field. Each optic is finished with a tough Type III hardcoat anodized black finish to keep your scope looking great for years.

The Primary Arms 1X Prism Scope is shipped with a riser mount that results in a centerline height of 1.41”, the standard height of an AR-15 platform front sight. A low base (1.05” to centerline) is also available as an accessory, which is useful for mounting to an AK-47 or other rifle with a stock located lower than the optics rail. In addition to these two mounts, two spacers are available for purchase to accommodate different applications and shooter preferences. When used with the riser mount they will result in a height to center line of 1.535”and 1.64”.

The 1X Prism Scope is compatible with all industry standard microdot style mounts, including QD options such as the popular American Defense AD-T1 series. When choosing a mount, note that the height from centerline of the scope to the surface where the mount attaches is .25” taller than a typical 20mm microdot. Therefore, if a mount normally results in a 20mm microdot sight height of 1.41”, installing it on the Primary Arms 1X prism scope will result in a taller height of 1.66”.

Great help for those with an astigmatism and the BDC works as advertised

by -

I have an astigmatism and though I'd give this 1X prism a try. It replaced an Aimpoint PRO on my 16" 5.56 rifle. I paired up the cyclops with a one of the new Holosun 3X magnifiers. Took it to the range and shot it out to 200 yds. The BDC works as advertised after a 50yd 0 with 64 grain .223 powerpoint ammo. Had a nice grouping of center mass hits out to the 8 ring on the target. The glass is very clear and the diopter lets you focus the reticle to your eye very easily. Definitely worth the money!

Great Product! Great Price!

This optic is solidly built. I can’t see anyone describing it as “fragile”. It is robust without presenting with excess weight.

The factory supplied base is wonderful. I wouldn’t bother upgrading it. The entire setup has flawless fit and finish. Adjustments are firm.

My sole concern is that the reticle is so profoundly small. The horseshoe is perfectly observable and does make a nice aiming point However, the chevron is difficult to see. I would like to see PA lose the horseshoe, and double the chevron. JMHO.

I would not even think of returning the optic to PA due to my few concerns. I am likely to purchase an additional one for my AR15 .22LR upper.

A 1X Mini ACOG at 1/4 The Price!

by -

After using one on three different rifles the past few months I just bought two more. These are like a 1X mini acog, only with better features - adjustable illumination and adjustable diopter focus - at 1/4 the price!

A+++. 👍👍👍

Great little optic made better when paired with a 3x magnifier. The "3000 hour battery life on a medium setting" however is a little misleading. 3 different brands of batteries, left at setting 5, I averaged 92 days or just a little over 2,200 hours. But 3 months of "set it and forget it" isn't bad at all. My astigmatism has made me transition away from standard red dots to LPVO's or prismatic sights and this optic works great for me

9/10

Wow! I was so impressed with this optic. The glass is clearer than my EOtech’s, and the etched reticle is very fine. The BDC is very useful, especially with a magnifier. The donut of death on the ACSS reticle makes quick shots to a torso sized target very easy. This optic replaced my Eotech XPS2. Very pleased with it. My only gripe is that it is not as durable. From light training, a dent formed on the top of the scope, making the threads for a sunshade unusable. I was not planning on getting a sunshade, so it doesn’t bother me, but it concerns me about whether this optic would hold out through a combat scenario. As a civilian no longer overseas, I don’t need to worry about that, but I like knowing my equipment is bombproof. For $239, you’re getting the best you can get in this price range, no doubt about it. You won’t regret picking this versatile, clear, well thought out optic!

Built Tough, Built To Last

Absolutely love this prism scope. I have been running it on a 300 Blackout (after relpacing a red dot with it) for the last 4 months are so in everything from rain and mud to high winds and dust. In all conditions, it has performed flawlessly. Target aquisition is smooth, quick and snappy when I'm on the go giving me clear, crisp views of everything down range. The chevron tip is as clear as a bell and I no longer have to worry about how much battery life I have left as it can be run without illumination thanks to its etched reticle. In fact, I can count on one hand how may times I've had to use its illumination capabilities as the reticle works perfect without turning it on under normal to low light conditions. The 3 times I've actually turned on the illumination were in extremely low light conditions, and again, flawless. Built tough and built to last. Love it.

Add a KISS reticle option please.

by

With the awesome glass, eye relief, and build quality. This is as close as anybody has gotten a prism scope to be like a red dot. It is so quick to get a good view of your target. I have one complaint, and that is the reticle. It may be great for some shooters, but I find it too busy for a 1x option. Plus, the limited brightness options makes it difficult to pick up on bright, sunny days in my opinion. If you had the KISS reticle as an option, with better illumination, Primary Arms would crush the 1x prism competition. Regardless of the reticle, I am glad I purchased this scope. Still, the reticle and limited brightness for direct sunlight shooting makes me wish that the KISS reticle was an option.

Dollar for dollar an excellent optic.

I've been looking for and researching for an optic that could help with my eyesight issues. I love a red dot just as much as the next guy. But astigmatism got me. So I took a chance with a Zero Magnification Prism style optic known as the Cyclops from PA. Glad I did. Now I have a quick CQB optic with an etched reticle that provides BDC, eye focus adjustment, and illumination that I can count on even with eyesight issues, and if the battery runs out, I still have an optic. I gave it 4 stars to be fair because I have not taken it to the range but I suspect it will perform as promised and it has plenty of 5 star reviews as it should. Dollar for dollar, and excellent optic.

Almost perfect
