Last refreshed Jun 22, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
A capable low power variable scope for the price, with clear glass and a mount included, but budget for slightly more weight and a tighter eye box than the listing suggests.

Overview
A 1-10x28 low power variable rifle scope with a 34mm tube, second focal plane reticle (BDC B1 or MX1 box) and a built-in throw lever. Ships with a 34mm offset cantilever mount and flip-up lens covers, aimed at AR-pattern rifle owners who want one scope for close and mid range work.
This is a budget LPVO built around a wider 34mm tube for extra light transmission and a shorter body with a wider eye box than Monstrum's earlier optics.
- Second focal plane reticle stays the same size at every magnification for visibility
- Integrated throw lever for fast power changes
- Includes 34mm offset cantilever mount
- Spring loaded flip-up lens covers included
Who it's for
Fits AR-10 and AR-15 owners who want a single scope that works both eyes open at 1x and dials up to 10x for longer shots, without paying for a premium tier LPVO. Less suited to shooters who need generous eye relief or a lightweight build.
Pros and cons
- Clear glass reported across the full 1-10x range
- 34mm tube pulls in noticeably more light
- Turret clicks track well enough to zero in a few shots
- Mount and flip-up lens covers included
- Heavier in hand than the listed weight, measured near 19 to 23 ounces with mount
- Eye relief runs short at roughly 5 inches
- Fit and finish varies by buyer on this overseas build
Performance notes
The integrated throw lever speeds up magnification changes in the field, and turret clicks are reported as crisp rather than mushy. One reviewer's own measurement put eye relief around 5 inches, which narrows the eye box more than typical LPVOs and rewards a consistent cheek weld.

Frequently asked questions
What magnification range does the Monstrum Spectre cover?
It runs 1-10x through a 34mm tube, using either the BDC B1 or MX1 box reticle depending on which version is ordered.
Does it come with a mount?
Yes, a 34mm offset cantilever scope mount and spring loaded flip-up lens covers ship with the scope.
How is the eye relief?
One buyer measured it at about 5 inches, tighter than many LPVOs, so expect the eye box to be more position sensitive.
