It is 2.48 in (63 mm) long, weighs 5.5 oz (156 g), adjusts in 1 MOA clicks with 120 MOA of windage and elevation travel, gives a 76.5 ft field of view at 100 yards (25.5 m at 100 m), and is sealed to IP67 and nitrogen-purged.\u003c\/p\u003e\u003cp\u003eThis is the smallest and lightest prism in the Primary Arms range — close enough to a micro red dot in size and weight that most shooters would not tell them apart on the rifle. What separates it is that the reticle is etched into the glass rather than projected as an LED, which means shooters with astigmatism see a clean horseshoe and chevron instead of the smear or starburst a red dot produces, and the reticle remains usable with the illumination off or the battery flat.\u003c\/p\u003e\u003cp\u003eBecause it uses the H1\/T1 footprint, it drops onto the very wide range of mounts already made for micro red dot sights, so an existing mount will very often carry it straight across.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThis is the red-illuminated Cyclops Gen II version.

A prism scope's reticle is etched into the glass and viewed through the optic's own focusing system, so it is resolved by the same corrected optical path as the target, whereas a red dot projects an LED that an astigmatic eye commonly sees as a smear, flare or double image.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat mount does the SLx 1X MicroPrismT need?\u003c\/b\u003e\u003cbr\u003eThe SLx 1X MicroPrismT uses the H1\/T1 micro-dot footprint, so it fits the wide range of mounts made for micro red dot sights, and a 2.26 in mount is supplied in the box.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat does the ACSS Cyclops Gen II reticle do?\u003c\/b\u003e\u003cbr\u003eThe ACSS Cyclops Gen II combines a bold horseshoe that draws the eye quickly to the centre at close range with a precise centre aiming point and ranging features for estimating distance to a target of known size.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDoes this optic work if the battery dies?\u003c\/b\u003e\u003cbr\u003eYes.
