After rigorous field testing, this optic has been given a Silver-tier rating by the National Tactical Officers Association.
SLx optics are the heart of our lineup. The trusted optics that have
built our reputation through the years. Although many SLx optics will be
familiar to Primary Arms fans, we are always pushing forward with new
generations and adding even more options in response to the demands of
our loyal customers.
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:

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
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.
Prism Scope body is just as tough as the rest of our 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.
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”.
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”.
prism scope is not a red dot sight. It is a prism scope, meaning that
the reticle is visible regardless of battery power. The etched ACSS
Cyclops reticle works more like a typical rifle scope than a red dot.
Magnifiers will work with PA1X when placed in the standard configuration
behind the PA1X. Special attention will need to be paid to focusing the
magnifier on the reticle ensuring it is crisp and clear. This
configuration can be used without introducing parallax or point of aim
shift. In addition to the configuration described above a typical
magnifier can be placed in front of the PA1X prism scope, however it
will introduce a large amount of point of aim shift, parallax and
overall unreliability of the optical system. It is not recommended to be
used in this configuration.
Due to the fundamental nature of the
PA1X prism scope’s optical system, it operates differently than a
typical red dot. It can be used in line (co-witness) with iron sights
like a typical red dot. When placed in line with iron sights the front
sight can be visible through the scope. However, the iron sights should
be zeroed while in line with the PA1X to account for any point of aim
shift introduced by having the PA1X in line with the iron sights. It
should also be noted that co-witnessing of iron sights is not necessary
with the PA1X like it is with a red dot sight, because the ACSS Cyclops
reticle is always visible regardless of battery voltage or even having a
The Primary Arms 1X Compact Prism Scope with
ACSS Cyclops reticle is the smart alternative to red dots for shooters
with astigmatism or other eye issues, or shooters who want advanced ACSS
reticle features in a true 1x optic. This product is covered by the
Primary Arms Lifetime Warranty.
