HOUSTON, TEXAS – The Primary Arms 3-18×50 First Focal Plane scope is one of the most eagerly anticipated precision rifle scopes of the year. Now the wait is over. The 3-18×50 FFP scope with HUD DMR .308 reticle is in stock and ready to ship, and the 3-18x50FFP scope with HUD DMR 5.56 reticle is available for pre-order, with anticipated availability in late November to early December 2018. 

Push the resettable windage and elevation knobs towards the scope tube to lock them, preventing accidental turret clicks. Pull them away from the scope tube to make crisp, repeatable 0.1 MIL adjustments. Control both parallax adjustment and partial red reticle illumination from the same knob location on the left side, freeing up tube space for better mounting flexibility. Keep the reticle crisp, using the quick adjust diopter ring, and reposition the power ring fin to suit your personal preference for maximum leverage when adjusting magnification on the fly. 

The brain of this scope is the exclusive, patented ACSS HUD DMR reticle, proven effective in our 4-14×44 FFP scopes and our Platinum 6-30×56 FFP scopes. HUD DMR is a holdover reticle that incorporates target range estimation, bullet drop compensation, wind holds, and advanced moving target leads for three target speeds, all without doing math or physical scope adjustment. Due to the first focal plane construction, the reticle’s calibrations are true at all magnifications. There is no guessing or “Kentucky windage” with HUD DMR—the scope provides detailed, carefully tested holdover points to apply in a wide variety of real world shooting situations. Glass quality is outstanding for a precision scope priced at $499, and the 3-18×50 FFP scope is covered by the Primary Arms lifetime warranty.
