    • Monstrum marauder 6-24x50 scope
Color: Black Style: FMR03 Reticle
Over the years I have purchased several Monstrum products; each scope has served me well and held up to the harsh Utah environment. The Monstrum Marauder 6-24x50 rifle scope with adjustable objective is a solid piece of equipment. I purchased this scope as it definitely is a value for the price I paid for it. I applaud Monstrum for producing a quality product at a sub $100 price level, with a lifetime warranty. The scope rings (included with the scope) are solid and will hold up to recoil of a large magnum rifle. I particularly enjoy the 6-24x50 magnification, it makes keeping my eye on the target much easier than a scope with lower magnification or using standard iron sights. The weight and length of the scope plus the easy throw lever to adjust magnification 6-24x makes this a fantastic choice for just about any hunter or target shooter. Would I buy another Monstrum scope, definitely! Next scope I purchase from Monstrum will be their Beast model, it’s a winner as well! ... show more

Color: Black Style: FMR03 Reticle
Great clear optics. I can finally see the bullseye at 100 yards. Holds zero. Just that after I mounted it and boarsited it i went to turn on the light and it didn’t come on. Tried a new battery. Still same. Love the scope. Just wish the light worked
