Description
The Primary Arms SLx 1-10x28 Rifle Scope gives you a wider zoom range than a typical 1-6x LPVO while keeping a usable 1x sight picture up close — true 1x for speed, dialling to 10x for target ID and longer shots. It runs the second-focal-plane ACSS Griffin M10S reticle, purpose-designed for 1-10x SFP optics.
A bold horseshoe and chevron drive close-range speed, while the MIL grid and ranging stadia support holdovers and range estimation at magnification. Built on a 34mm 6061-T6 aluminium tube with NV-compatible illumination.
