Overview
The Monstrum Terminator FTR110B-CM9 is a 1-10x first focal plane rifle scope built with extra low dispersion glass and a removable exoskeleton mount, aimed at shooters who want a fast 1x sight picture plus usable 10x magnification for distance.
The exoskeleton mount doubles as an integrated picatinny base and can be removed entirely to run the scope as a standard 30mm tube, which adds flexibility but also adds weight, the full setup runs 2.6 pounds versus about 1.5 pounds for Monstrum's traditional LPVO scopes. Because the reticle is first focal plane, holdover marks stay accurate at any magnification rather than only at one fixed power.
- 1-10x first focal plane magnification with extra low dispersion glass
- Exoskeleton mount with integrated picatinny base, removable for standard 30mm tube use
- 1/2 MOA or 0.2 MIL adjustments depending on version
- Reticle choices across CM5, MM5, CM7, CM8 and CM9
Who it's for
Shooters who want first focal plane ranging without giving up a fast 1x sight picture are the target audience here, and the exoskeleton mount's extra weight is the tradeoff they're accepting. Anyone chasing the lightest possible LPVO setup should look at Monstrum's traditional tube scopes instead.
What buyers say
From Amazon customer reviews.
Buyers new to LPVOs called the glass clear and the zoom lever smooth even on the heavier side. One reviewer flagged that they received what looked like a different focal plane reticle than ordered and noted the front trim piece isn't removable like the rear, though they still found the mounting solid.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reviewers describe the glass as clear even as a first LPVO purchase
- Zoom lever pulls smoothly from 1x to 10x
- Reticle and adjustments read as crisp and solid
Performance notes
ED glass and anti-reflective coating are aimed at reducing chromatic aberration and keeping the sight picture bright across the zoom range. Adjustments run 1/2 MOA per click on the MOA version or 0.2 MIL per click on the MIL version, and because the reticle is first focal plane, a 1 MOA hashmark reads as 1 MOA regardless of magnification.

Questions about the Monstrum FTR110B-CM9
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Is the Monstrum Terminator FTR110B-CM9 first or second focal plane?
It's first focal plane, so the reticle's holdover marks scale with magnification and stay accurate at any zoom level, though one buyer reported receiving a different configuration than ordered, worth confirming on arrival.
How much does it weigh?
With the exoskeleton mount attached it runs about 2.6 pounds, versus roughly 1.5 pounds for Monstrum's traditional LPVO scopes without that mount.
Can the mount be removed?
Yes, the exoskeleton can come off and the scope used as a standard 30mm tube.
