The Primary Arms SLx 1X MicroPrismT with green illumination delivers red-dot speed with the clarity and durability of an etched reticle — usable even with the illumination off, ideal for shooters with astigmatism. The green emitter many find faster to pick up. This model uses the ACSS Cyclops Gen II reticle on the popular H1/T1 footprint.
Green illumination spans 13 settings (3 night-vision) with AutoLive motion-sensing. It's tiny (2.48in, 5.5oz), sealed to IP67 and nitrogen-purged.
