Monstrum released the Challenger 5-25×56, a new budget FFP long-range scope. This improves upon their older G3 4-24×50 long-range scope with features appealing to PRS style shooting with a larger 56mm objective lens, zero-stop turret, and a Christmas tree reticle. Remarkably it has all of that at a lower price than the G3.




The Challenger ships with several accessories including a decent set of high-height rings. It does not include a sun shade which many budget PRS scopes include. The Challenger has a built-in fin on its magnification ring so doesn’t need an additional throw lever.
The illumination knob has 6 levels of brightness with an Off in between the settings. The elevation turret is non-locking but has a built-in Zero-Stop activated by screwing down a worm screw accessible under the turret cap. An odd design feature is the screw-down turret top on the elevation which covers the turret screw and access to the Zero-stop worm screw. This makes resetting the turret zero a little bit more work.
The windage turret is a more typical, push-down-to-lock design. It has an exposed slotted turret screw top to reset the turret to 0. Unfortunately, my model’s turret markings did not exactly line up with the tube’s indicator dot, a tell-tale sign of cheaper, budget construction.
Glass and optical quality are also where Monstrum compromised to achieve its low price. The image at its lowest of 5x shows noticeable chromatic aberration. The image was not sharp from center to edge, with noticeable softening and distortions at the outer 1/4 of the scope image. Color fidelity was good but with a slightly warm balance. The was average for a budget PRS scope: tight.
The new reticle is the Challenger’s best improvement over the G3. It is a more tactical style reticle than other PRS Christmas tree reticles, with a thick “+” as its central aim point. This made the reticle much more usable from 5x-16x than typical FFP reticles but was too thick for Precision target shooting as it obscures the central X ring of a bullseye. This reticle will be more appealing to hunters than Benchrest shooters.
For long-range hunters or gong plinkers on a budget, this scope is priced low enough to be worth a try. As a competition PRS scope it has disappointing optical performance. But factoring in its jaw-dropping street price of $199, the value calculous for this scope shifts radically toward its favor.
