Primary Arms SLx 3-18x50 Gen II Product description

Primary Arms SLx 3-18x50 Gen II Product Description

Wide Magnification Range: The 3–18x zoom range provides exceptional versatility, supporting precise shot placement from mid-range distances to extended long-range engagements.

ACSS Precision Reticle: Incorporates advanced ACSS reticle technology, combining bullet drop compensation, wind holds, and ranging features for fast and intuitive shooting.

First Focal Plane Accuracy: The reticle scales with magnification, maintaining consistent subtensions for accurate holdovers and ranging at all zoom levels.

Refined Turret System: Exposed tactical turrets deliver precise 0.1 MRAD clicks with improved tactile feedback, complemented by a zero-reset system for dependable adjustment control.

Extended Adjustment Capability: A generous internal adjustment range supports effective dialing for long-range shooting applications.

Low-Light Optimized Illumination: Multiple brightness settings with intermediate off positions ensure clear reticle visibility in low-light conditions.

ABOUT THE SERIES

The Primary Arms SLx series represents the brand’s mid-tier optics line, combining versatility, modern design, and proven functionality across a broad spectrum of shooting applications.

Defined by its wide-ranging portfolio, the SLx lineup includes low-power variable optics, mid- and high-magnification riflescopes, as well as prism and micro optics. This diversity allows the series to effectively cover everything from close-quarters scenarios to extended long-range shooting.

Could you please tell me how much the windage turret stands out in millimeters? Measured from the outer end of the tube. I want to run this scope with a reddot in an offset mount and don't want the windage turret blocking the sight of the reddot. Thanks!

by Andreas

The windage and elevation turret stands out for around 27-28mm measured from the outer end of the tube to the end of the turret.

Great Scope

Awesome scope, I have this spray-painted on my HK MR308 in FDE. I use the one with ACSS HUD DMR reticle. I can highly recommend this scope. Some friends of mine use the BPR Mil reticle and the love it too. I am more into the BDC-reticle. And so far this seems to me to be the best BDC reticle available.

I also own some gold and platinum line Primary Arms scopes - I still love this scope too. The glass is little bit better on the gold line and fantastic on the platinum line. However, the glass is already pretty good with this scope.

Wow!!!

I own S&B pm2 3-20x50 and Minox ZP5 5-25x56 and didn't expect much, but this scope is worth double as much! Paralaxa and illumination knob, need a strong hand.
The scope has all you need. The ACCS DMR is the krone of the scope, better then PL4F and MR4!
