Primary Arms SLx 3X MicroPrism Scope Green Illuminated ACSS Raptor 5.56/.308 Yard Reticle

The Primary Arms SLx 3X MicroPrism Scope with green illumination (part number 710037, SKU PA-SLX-3XMP-RAPTOR-5YP-G) is a fixed 3x magnification prism scope with a glass-etched ACSS Raptor 5.56/.308 Yard reticle illuminated in green. It is 2.95 in (75 mm) long, weighs under 8 oz (227 g), adjusts in 1/4 MOA clicks with 80 MOA of windage and elevation travel, gives a 38 ft field of view at 100 yards (12.7 m at 100 m), and runs up to around 29,000 hours on a CR2032 cell across 13 brightness settings, three of them night-vision compatible.

Two things make this variant worth choosing. First, it is a prism scope: the reticle is etched into the glass rather than projected as an LED, so an eye with astigmatism resolves it sharply instead of seeing the smear or starburst that red dots produce for many people. Second, the emitter is green, and because human vision peaks in the green part of the spectrum, that centre often registers faster against foliage and in the flat overcast light that covers most of the British shooting year.

How it compares

This is the green-illuminated black 3X. The same optic is offered with red ACSS Raptor illumination and in Flat Dark Earth with red illumination. For more magnification and a milliradian grid, see the SLx 5X MicroPrism with the ACSS Aurora MIL reticle; for an unmagnified prism, the GLx 1X MicroPrism with green ACSS Cyclops illumination. Browse the Primary Arms prism scope range and all prism scopes, and read our guides to how prism scopes work, astigmatism and red dot sights and green versus red illumination.

Ideal for

• Shooters with astigmatism who see red dots as a smear, flare or double image
• Deer stalking and woodland shooting, where a green centre stands out against foliage
• Civilian Service Rifle and practical rifle in 5.56 or .308 under British overcast
• Night fox and vermin control at dusk, where a lower brightness setting is enough

Key features

• Magnification: Fixed 3x — real magnification in a body under 3 inches long
• Reticle: ACSS Raptor 5.56/.308 Yard, etched into the glass, with bullet drop holdovers, ranging, wind holds and a precise centre chevron, calibrated for 5.56 and .308 in yards
• Astigmatism: The etched reticle is resolved through the optic's own focusing system, so it stays sharp for eyes that see LED red dots as a smear
• Illumination: Green, 13 settings of which 3 are night-vision compatible, with AutoLive motion sensing, up to around 29,000 hours on one CR2032 cell
• Backup: Fully usable with illumination off or the battery flat
• Field of view: 38 ft at 100 yards (12.7 m at 100 m)
• Turrets: 1/4 MOA per click, 80 MOA of windage and elevation travel
• Mount: Ruggedised mounting system with 8 height options, on the mini-prism footprint
