Scope arrived on time and is really amazing. The construction is solid and the mounting was a breeze. Literally less than 10 minutes. The scope is crystal clear and I am highly impressed. Only con I have is the illumination turret is ridiculously hard to turn. Maybe it just takes time to break in but it is God awful tight, besides that the scope is great. Functions properly and you cant beat it especially for the price I would definitely recommend.

The problem I have with the MX1 reticle is that the DOT in the reticle is huge. At 50 yards it covers a four inch target almost entirely. At 100 yards the target is impossible to see because of the size of the dot. It looks like the dot is 8 MOA. If you're shooting at an elephant, it may work. But for more refined shooting, it doesn't work. It's a shame because the scope is well made and it has nice turrets.

I purchased this for a rifle build for short range hunting and I love it. Its perfect for the application I needed it for. Its quality build for the one I received and has great clarity. This will be a brand for my go to optics from here on out. And I bought another one for as a replacement for an out dated optic on my hunting rifle for this season

When I received the Monstrum Stealth 4x30 Sight, I was impressed as to the care that had been taken in packaging it, unlike most Chinese-made items like this. Upon assembling the sight and mounting it on my MSR, the quality of the optics became evident. The image was clear and the green and red illumination settings of the sight appear to be excellent. I used a laser boresighter to do a 25 yard sight-in and was amazed how easy it was to adjust the turrets, not needing a screwdriver to adjust them. Now I will be heading to the range for final sight-in. Again, the quality of the Monstrum Stealth 4x30 Sight appears to be excellent and is exactly want I needed for my MSR.

I own 3 of this particular model. All mounted on AR-15's. Calibers 7.62, 5.56, and . 300 ACC. These little scopes are tough. They are very clear. The reticle is very visible even without using the internal illumination. All 3 rifles consistently group around 3/4" at 100 yards. I also own the 3x model and it's as dependable and clear as the 4x. I'm replacing all of my existing optics with monstrum scopes one at a time. I have that much confidence in the quality and clarity they offer. Buy it, you won't be disappointed.WHOA!!!!!!!!! FURTHER REVIEW!!!!!!! PLEASE READ!!!!!!!! As stated above, originally I was pleased with these scopes. Now 6 months to a year later, 2 of the 3 are in the woods after I slung the as hard as I could sling. The reticle on these scopes will cant left or right after a while. One moved about 20° and the other looked like it was floating in water it moved so much. I tossed em down in the woods. Yes Monstrum offered full replacement but I had to pay shipping. That cost was ridiculous. Damn near half the price of these scopes. They zero well, they are clear, seem decent quality, but the crosshair will move. I hadn't fired the guns mine were on in months either. They were on 5.56 and 300 blackout and sitting in a gun safe. I won't purchase Monstrum again.
