Overview
The Monstrum G3 is a 6-24x50 first focal plane rifle scope with an illuminated MOA reticle, adjustable objective and included picatinny rings, sunshade and flip-up lens covers. It targets mid to long range shooters stretching out toward 1000 yards on a budget.
Because it's first focal plane, the reticle's MOA hash marks scale with the target at any zoom, so holdover math works the same at 6x as it does at 24x. The adjustable objective knob handles parallax at distance. Owners describe it as heavier than a typical scope, which several attribute to the internal construction, and more than one reviewer needed a warranty replacement before landing a good copy.

Frequently asked questions
What magnification range does the Monstrum G3 6-24x50 cover?
6x to 24x through a 50mm objective lens, built for mid to long range shooting out past 500 yards.
Does the G3's reticle change size as you zoom?
No - it's a first focal plane reticle, so the MOA hash marks stay proportional to the target at any magnification, which is what makes holdover consistent at low and high zoom.
What comes in the box with the Monstrum G3-FFPS62450-R-FDE?
High profile picatinny scope rings, a detachable sunshade and a set of spring-loaded flip-up lens covers ship with the scope.
