Compact 3x prism optic with ACSS Raptor reticle
The Primary Arms SLx 3x MicroPrism represents a revolutionary approach to magnified optics for AR platforms, combining the compact footprint of a red dot sight with fixed 3x magnification and an etched reticle that remains visible even without battery power. At just 9.6 oz and barely longer than a standard red dot, the MicroPrism delivers a unique value proposition for shooters seeking simplicity, reliability, and extended effective range.
The prism optical design offers a critical advantage for shooters with astigmatism - unlike red dot sights that appear as blurry starbursts to astigmatic eyes, the etched glass reticle of the MicroPrism appears crystal clear regardless of eye condition. The ACSS Raptor 5.56/.300BLK reticle provides automatic ranging using the horseshoe and BDC holdovers calibrated for common AR ammunition, transforming a basic carbine into a capable 500-yard platform.
With its compact size, the 3x MicroPrism excels in roles where a traditional LPVO is too heavy or bulky - patrol carbines, truck guns, and compact defensive rifles. The fixed 3x magnification hits the sweet spot for most defensive and tactical scenarios from room distance to 300+ yards, while the extremely generous eyebox allows for rapid target acquisition comparable to a red dot.
Add the Primary Arms SLx 3x MicroPrism to your build and see how it enhances your platform.
