More from this brandAll Monstrum rifle scopesOverview
A rifle owner with a Picatinny rail gets a fixed four power prism scope here, with a BDC reticle and a black aluminum body in a tactical style. The prism design shortens the housing.
Fixed power and a short body give a quick, uncomplicated sight picture for carbines and range guns. The limitation is that there is no zoom, and the listing omits eye relief, weight and warranty.
Who it's for
Rail-equipped rifles used at short to moderate range, where a fixed magnified optic with a ballistic reticle is useful. Long range shooters and anyone who needs adjustable power should choose a variable scope.
Pros and cons
- Compact prism design
- Fixed power is simple
- BDC holdover marks
- Eye relief not listed
- Warranty not listed
Performance notes
A prism folds the light path inside the housing, which shortens the optic compared with a tube scope. Fixed power means no magnification changes under stress, and the BDC marks are set for one level of magnification. Field of view is fixed by the optics, not by a zoom setting.
