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.
- 6-24x50 magnification with FFP MOA reticle
- Illuminated reticle with adjustable brightness
- Adjustable objective for parallax correction
- Rings, sunshade and flip-up lens covers included
Who it's for
Suits shooters who want FFP holdover accuracy for 300-1000 yard work without paying premium-glass prices, including AR platforms set up for extended range. Not the pick for anyone chasing the lightest possible optic or glass that matches a $1000 scope in low light.
What buyers say
From Amazon customer reviews.
Several buyers are repeat purchasers who now own multiple G3 magnification variants and say they behave the same. A few received defective copies (an inconsistent illumination button, air bubbles in an internal lens, an off zero) and report Monstrum replacing the scope quickly. Owners note the eyebox and eye relief run tight, the scope mounts high enough that shorter rings help, and the parallax and brightness knobs are stiff. One long-term owner has it soaking up 8mm Remington Magnum recoil for several hunting seasons without needing to rezero.

Questions about the Monstrum G3-FFPS62450-R-FDE
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
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.
