  • Great beginner scope at an unbeatable price.
This is a great introductory long range scope for someone looking to get into the long range game. The turrets track accurately and the glass is acceptable for the price. My reticle passed the plumb bob test, you should check yours. Use? I recommend this scope for beginners to learn how to spin dials, properly set the AO and practice proper head positioning. Speaking of proper head position you will need to get very good at it as the 16x eye box is TINY. At 4x it's brighter that an acog has better eye relief and with practice you can scan a large area and engage targets quickly with both eyes open. If this is going on an AR style platform I recommend the monstum ultimate one piece mount and play with the magnification to determine the best location to mount the scope ( remember the eye box is TINY so you want it to be in just the right spot). The glass is acceptable out to 500 or so yards if you go much further thing get milky but still usable. I really like the simple moa reticle and once you test and learn the holds it is fast to make wind and elevation corrections without spinning dials. The reticle illumination is actually decent although aside from verifying zero and holds I really haven't found a reason to use them. This scope gathers enough light that even at dawn and dusk shooting into wooded areas I was still able to make out the dot without the illumination. I am using this for my spr setup and I carry this thing through the wilderness banging and bonking it the whole way and it has held zero. However! The couple of times I performed shoulder height drop test the poi shifted a few moa. I have scopes that cost 20 times more than the monstum that will are galaxies better than the monstum but this actually gets used because I'm not terrified of breaking/scratching/ruining it. In closing this thing is very heavy, feels cheap and has the smallest eye box I've ever personally used but I love it and use it every week without fear. If your a beginner this is the perfect tool to learn on and if your an experienced LR shooter it's a usable scope that you can ruck deep into the woods and not pucker everytime it bonks something. ... show more

  • Worth the money
This was my first experience with a Monstrum optic. I normally run Vortex, Leopold or Burris scopes, budget and warranty types. I was very impressed with the clarity, construction and all the details put into this scope. I've got it mounted on a ar-10 .308 rifle with about 2500 rounds thru it, never any zero issues. I can shoot the same hole at 100yds or bang steel at 500. Brass guts on the inside, very nice. ... show more

  • Good scope
Color: Black
Not a bad scope. Sunshade stripped while installing it, was going to return but don’t really need it. Tracks good on 6.5 creedmoor. Not as clear as they claim but overall a good scope for the price.

  • Great glass and extremely well made, my second purchase of this brand
Color: Black
2nd one of this brand that I have bought, really clear glass and extremely well made. This quality in another brand would be a lot more $$$$$

  • Bad scope rings
Installed scope on my 7mm Weatherby mag. Love the scope. The rings suck. Ran 3 rounds to sight in and broke off the gun. Now have to order new one's. Cost me $80.00 for new rings. In all good now love scope.

  • Awesome scope
Color: Black
Upon opening this scope you would think it's a high end scope, from the packaging to the quality of this scope, clarity is awesome along with the etched glass instead of wire cross hairs,first focal plane is great, you can't go wrong with this scope, I will be purchasing again when my new rifle arrives, well worth the money ... show more

  • Issues
Color: Black
Scope would not hold zero on a 224 valkyrie and the reticle was not true in the tube which made trying to re-zero at different yards even harder

  • Great scope reticle Not so much
Color: Black
I have had this scope now for a few months. Clarity and functionality are really great for the price. However the huge dot in the middle of the reticle makes this scope not usable for anything more than hunting. Anything at range and the dot covers the majority of what you want to shoot at. If they fixed this issue this would be amazing but as is it left me less than impressed. ... show more
