Style Name: BDCB1 Drop Reticle
Mounted on a 556 rifle. Great positive knob adjustments. Build quality seems solid. I actually like the longer look to this optic, I know there are shorter ones, but this one seems to fit my build perfectly. I like the 1 on -1 off style illuminated reticle knob. Instead of ramping up the intensity it allows users to increase each setting with a shut off between each setting.. meaning instead of having to cycle through all the brightness settings you can hover between the off and the brightness setting that works for you. My optic came “nearly” zeroed, only had to adjust the elevation was all. Got it dialed in 3 shots at 25yards. Magnification/built in throw lever works well. I played with that a bit at the range. I also like the mount that came with this optic, it was low enough profile I don’t need a cheek riser. Time will tell with this optic, Monstrum has a few optics with lifetime warranties and this is one of them. Which at the very least means if something does go wrong, I can get it fixed.. so I like that as a type of protection with this optic. Some of their other optics have 1 year warranties so take that for what you will. With my range day and initial impressions on build quality, I’d say that at this point I can see myself buying another one of these scopes.

Installed on a 300 BLK AR, works great, holds zero after a year of use. Only problem is one of the flip caps broke…

Style Name: BDCB1 Drop Reticle
This a well made scope and considering what you get with it very very good price. This is an illuminated optic with a one piece mount, flip up covers, extra screws and a extra battery for $100. I've only put 40 rounds thru my rifle after mounting (AR 5.56) intial zero and sighting had zero issues. My only concern is the windage adjustment turret is pretty stiff and it's a hard to hear and feel the clicks when adjusting, the elevation turret doesnt have this issue. The magnification ring is also pretty stiff but its not a deal breaker, the illumination is bright and clear, overall so far I'm pleased with this product, we will see how it holds up with use

Style Name: BDCB1 Drop Reticle
For the price, I really don’t have much to complain about. The glass is clearer than SIG Tango MSR’s I have. Eye relief/eyebox is a little finicky especially at full zoom. But overall seems to be a sturdy optic for budget builds. Will be testing it out next deer season.

The scope is pretty decent for what it is. I own a few Monstrum scopes. This one does have 2 what looks like bubbles in the coating on the glass. It's not so visible when it's illuminated but stands out pretty big when it is. I doubt I'm going to use the illumination plus I'm past the 30 day return on Amazon. I didn't mount it right away so make sure you check it.
