Competitive shooters, long range enthusiasts, and long range hunters demand a level of precision that is not found in standard hunting and target scopes. The RS.4 Riflescope was specifically designed for those who require maximum precision when minor adjustments can make all the difference.

This purpose-built rifle scope features a first focal plane, 5-30x zoom range, side parallax adjustment, 4 level red and green reticle illumination, and the option for MOA or MIL-based reticles. Mechanical zero stop with positive stops ensure a return to your original zero after every dial. With a broad magnification range and precision dialing capabilities, the RS.4 is our recommended rifle scope for precision rifle shooting competitions and long range enthusiasts. 

Just like all rifle scopes in the RS Series, the RS.4 features crystal clear ED glass for tack-sharp clarity, a silky focus mechanism, precision-milled adjustments, solid click detents, and durable anodizing to resist heavy use.

The Maven RS Series represents our elite line of rifle scopes, designed to fit your specific needs, delivered for a fraction of the cost to comparable rifle scopes and stacks up with the most celebrated and expensive scopes in the world.
