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”.

Unusable

by -

I may have received a lemon. The reticle is so small it would fit inside the reticle in the example they display making it unusable. It is basically a red dot because you can’t use any of the etched markings. Quite heavy for a simple 1x.

Great Prism Optic

by -

Looks great on my AK105 and AK Master Mount rear biased scope mount. In order to mount this optic as low as possible on a Master Mount I had to use the super low mount from one of my MD-25 red dots. Did I mention this has a T1 footprint? Well now you know.
Zeroing was a breeze, but those turret cap lanyards can be a nuisance. Once zeroed slapping steel at 200 and 300 yards was a non issue. Lens covers are a nice addition but I ditched the rear one and inverted the front one.
If you have older like me and have an astigmatism, prism optics are your friends. I can't stress that enough.

Only Dot close would be Eotech

Once you master the holdovers, this item will change the game. The holdovers are very clear and nice, making it well worth the purchase. The etched reticle is ideal for an end-of-world scenario.

Passes swallow test. Scope was to big to fit in my mouth. I then proceeded to mount it on a drill gun. This served no purpose at all. I would recommend this scope to anyone who has lungs and a heartbeat.

Best I've tried yet. Saving up for new gen

by

I highly recommend this prism for anyone. Can't wait to get my hands on the new micro. I didn't have my first Primary Arms optic for a month til I order 2 more. Great quality at the best value out. Thank you PA for looking out for the everyday american.

Great buy

Can’t find anything wrong with it, just as good or better than more expensive and big brand name sights. Actually better than what I expected. I’ve heard they are made in the same plant as Vortex. I don’t think you can beat the price and quality is equal to Vortex.

Impressive optic

by -

Solid ACSS optic. I own many optics from Primary Arms and highly recommend them. They are clearer and better than many more expensive name brands. 👍👍

Excellent Optic Very happy with it the ACSS is great because its always there

Still works

by -

I purchased a 1st generation Cyclops when they first came out and have had it on my 300 blackout pistol until just recently when I replaced it with a 2nd generation Cyclops. I moved the 1st gen scope to my 5.56 pistol. I have banged it around a lot since I got it and it has some scars to prove it but it still works great just like it was new. It is a tough little scope.

Way better than a red dot

I am very glad I switched
