Primary Arms 3X Prism Scope
Editor's Review: This optic is virtually invincible and is built durable like an ACOG for less than 1/3 the price. The adjustable diopter is a wonderful feature and the ACSS Reticle simple rocks. In low light, we could adjust the illumination to where it did not overpower or obstruct our target in ultra-low light and the brightness could easily be adjusted to tackle brightness at any time of the day. An etched reticle is a great option should a battery fail in the field. Surprisingly, the optic was almost dead on zero as soon as we mounted it. We tested the Primary Arms 3X Prism Scope at 100 yards out of the box and did not even boresight it and the results were shocking. The Primary Arms 3X Prism Scope simply rocks and it is built like a tank.

Primary Arms 3X Prism Scope


The SLx optics are the heart of the Primary Arms lineup. The trusted optics that have built the Primary Arms 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 3X Compact Prism Scope Gen II with ACSS CQB 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. For even greater flexibility, the GEN II features a removable spacer to tailor the perfect height for both AR-15 and AK-47 platform rifles. Whether you're looking for a new scope for competition, hunting, or plinking, why look any further?

The heart of our tough 3X Prism Scope is the 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 an 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 holdovers! Two dots on either side of the inner horseshoe 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 Primary Arms 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.
