Overview
The Primary Arms SLx 1-6x24 Gen IV represents the culmination of four generations of refinement in budget-friendly LPVOs, earning "Scope of the Year" in the 2024 Industry Choice Awards. At an MSRP of $339.99, this scope delivers remarkable performance that challenges optics at twice the price, making it the benchmark by which all budget LPVOs are measured.
The Gen IV introduces significant upgrades including an integrated dovetail throw lever, upgraded optical system with clearer glass and sharper edge-to-edge clarity, and the new ACSS Nova reticle with fiber wire illumination for genuine daylight brightness. The true 1x magnification allows for both-eyes-open shooting with minimal tunnel vision or image distortion.
Built from 6061 T6 aluminum with IP67 water resistance, the SLx has proven its durability in extreme conditions - surviving drop tests onto concrete while maintaining zero, enduring heavy rain without fogging or moisture intrusion, and handling temperature extremes without issue.
