This Primary Arms MicroPrism is part of the SLx optics line. SLx optics built their reputation for innovation, reliability, and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.
For precision without compromise, the SLx 5x MicroPrism brings an extended range to this lightweight, ultra-compact design. Weighing only 8.5oz with a 3.31" overall length, the SLx 5x MicroPrism is comparable to many red dot sights, though its crystal-clear glass and 5x magnification offer improved precision at even longer distance than the 3x variant. Even at close range, the optic’s wide field-of-view and forgiving eye relief make it easy to snap on target. Because the SLx 5x MicroPrism uses an etched reticle with adjustable diopter, the user will always have a clear, crisp reticle image, even if they have severe astigmatism. When set to max illumination, the MicroPrism reticle is fully Daylight Bright. Paired with the AutoLive motion-sensing illumination technology, this optic provides an exceptionally long runtime at any brightness setting.
This package also includes the new ruggedized mounting system with industry standard mini-prism footprint, guaranteeing reliability and zero retention through heavy use and adverse conditions. Out of the box, this mount can be set for 8 different mounting heights and configurations, ensuring compatibility with any rifle system.
The ACSS Aurora 5.56/.308 Yard reticle is part of the patented ACSS Reticle series.
The ACSS Aurora 5.56/.308 reticle is a high-performance BDC reticle with a comprehensive toolset for ranging and engaging targets. This reticle uses yards-based holdovers, which are optimized for 5.56 and .308 cartridges and takes all the guess work out of getting first round hits.
EXPORT CONTROLLED ITEMS: These items are controlled for export and may require an export license from the U.S. Government. Buyer acknowledges that Buyer is responsible for obtaining all export licensing authorizations and filing all export documents prior to export from the United States.

ACSS Aurora 5.56/.308 Yard Reticle
The ACSS Aurora reticle is a high-performance BDC reticle with a comprehensive toolset for ranging and engaging targets. This reticle uses yards-based holdovers, which are optimized for 5.56 and .308 cartridges.

Target Ranging
Knowing the distance to your target is crucial to using the reticle effectively. The ACSS Aurora reticle allows you to range using target width, full height, or half height
WIDTH: To range a target by its width, simply hold your BDC over your target and find the stadia which most closely matches its width.
HEIGHT: To range a target by its height, use the numbered stadia to the sides of the center chevron.

Bullet Drop Compensation (BDC)
The ACSS Aurora reticle features built-in BDC holdovers to help you make fast, effective shots at variable distances. While this BDC can fit various cartridges and velocities, it is optimized for 5.56 and 7.62x51.
The BDC starts at the tip of the chevron and ends at the 800-yard stadia. To use the BDC, simply aim at your target using the stadia coinciding with the target’s distance. The ACSS Aurora 5.56 Yards reticle also features smaller marks between numbered stadia, representing holds at 50-yard increments

Wind Holds
Starting at 400 yards, your BDC includes dual-speed wind holds to help you compensate for crosswinds. Each numbered BDC stadia has two dots on each side. These dots represent a 5-mph or 10-mph crosswind hold at that distance.
Note: For the 400-yard stadia, only the 10-mph hold is visible, as the 5-mph hold falls inside the edge of the stadia itself.
