After doing a lot of research looking for a rifle scope with all of the features I was looking for, it seems that anything that had all those features was going to cost far more than I wanted to spend. Of course I looked at the Monstrum scopes, but was a bit put off by some of the comments from those that had reviewed them. After looking into the details of many of the complaints I decided to buy this G3 6-24x50 scope. I would have preferred to have the G3 3-18x50 but I could not find that scope in stock anywhere. The scope was well packed and in factory fresh sealed packing materials. It is surprisingly good looking. I happened to choose the Flat Dark Earth color to match my rifle, but discovered that is is a few shades darker than I expected. But it still looks good on the rifle. I did take one additional step before removing this from the box that it seems many other reviewers did not take. I read what instructions there were in the box before doing anything with the scope itself. I also viewed the Monstrum installation videos. There are only a few pages of instructions, but by reading them it appears that I have avoided the complaints that many have had. Everything is in the box that you need to mount the scope except perhaps some locktite for the mounting screws. I plan to get a slightly taller set of rings for this as the mounts that came with it are about 1/4 inch too low for me. The mounts use star screws and a wrench is included. If you take all the proper steps to correctly mount a scope it will take you a while to complete that step. It is particularly important to get the scope level on the rifle and that can take time and to do it right requires a rifle cradle to first level the rifle and hold it in place while mounting the scope. This appears to be one of the areas that others did not follow proper methods to complete. I did not find any of the issues related to the adjustments on this scope that were reported by others. The very first time one of the adjustments is turned they are hard to move. But if you establish that you are turning in the proper direction and then apply enough force to break them free, they seem to work just fine after that. I suspect that these are lubricated at the factory and the lubricant may bond over time if the scope sits for a while before being sold. Either way all the controls on this scope seem to work just fine. I particularly like the locking feature that requires pulling out on the adjustment and then pushing it down to lock it. The adjusters for reticule illumination and parallax are right beside each other on the left side of the scope. The cap to access the battery is in that same location. Some people reported that they could not turn the parallax adjustment without moving the illumination adjustment and/or unscrewing the battery cap. The first time I turned the parallax adjustment the illumination adjustment did move one click. But a few turns of the parallax knob solved this very quickly. Again I think this is due to the lubricant stiffening while awaiting unpacking and use. In any case all the adjustments on my scope appear to be working as designed and just as I expected. The is a first focal plain (FFP)scope. So any adjustment in magnification also magnifies the sighting reticle. This is a feature only found on higher end scopes that usually cost many times more than the Monstrum line of scopes. I like this a lot as it provides a scale of measurement that always matches the target. This allows the shooter to adjust for bullet drop and other factors before sending the round down range. Many reviewers complained about the illumination of the reticle being useless in daylight. First, the manufacturer says right in the description that the illuminated reticule if ONLY for low light conditions. But frankly, I had no trouble seeing the illumination except when pointed at very bright backgrounds. If I was aiming into a shadow or across dark objects like tree bark, the illumination is clearly visible and could be useful where lighting conditions vary across the scale if bright to dark. I am reluctant to say too much as to clarity of the view. For my eyes it is very clear. I did not see any of the fogging reported by other reviewers, nor did I have any issue with getting the reticle in clear focus. Only at the most Extream end of the magnification scale did I see anything that detracted from the view through the scope, and I believe that was caused by glasses and not the scope. Another complaint others had was an inability to zero the adjustment turrets after getting the scope zeroed. I have not had range time with this scope yet and i will happily update this review when i have. But i had no problem removing the caps on the adjusters and replacing them as i wished. It seems to me that those who could not do this may not know how it is done, on these scopes as i have seen different ways of doing this with different scopes. Either way resetting zero is not a problem. I have to stop at this point as i need to shoot the rifle to complete this review. But so far this appears to be a great buy. A lot of expensive features ad a very reasonable price. I would recommend this scope so far, and will report back after I have fire the rifle.

What an awesome scope! My husband loved his brother’s scope and found out that this was it. We ordered it and it came in and will be giving to him as a birthday gift. My husband can’t see that well and this really amplifies.

So, I want to clarify right off, this is not a top-quality optic. This is an affordable mid quality optic. I didn't expect this to be as nice as the equivalent Vortex, it also didn't cost $900. I am very satisfied with this rifle scope; it holds sighting and has great magnification. Clarity can only be achieved by focusing the optic, and that does take some time to get used to. How good is this rifle scope? I installed it on an ar10 6.5 Creedmoor and was able to put 15 of 20 rounds into a 5-gallon bucket at 1500yds. So yeah, it's good. I feel as though it is a reasonably accurate 600yd capable scope for my weapon and shooting ability, as that is specifically what I wanted and purchased this for.

After watching some YouTube videos and reading the reviews, I decided to give this scope a try. I decided to give it a real test and stuck it on my 8mm Remington magnum. It has lived there for several years soaking up the heavy recoil, and I have not had to rezero the rifle yet. It has survived several elk and deer hunting seasons. The optics are about on par with my diamondback tactical, maybe a little better. On the down side this thing is heavy probably because of the brass internals. The eyebox/ relief are very tight. The tracking is good, but not perfect. It tracked pretty close out to about 6-700 yards. Out to 800- 1000 it was not hitting where it should. This was just one session and I probably should test it again with a different shooting app, but my diamond back was dead on with the same app. Conclusion, this is a very good scope for the money but I feel it would be better in a hunting application over long range shooting. In that application I would it for a lower magnification. If you are curious about testing your skills at longer ranges this would be a good starter scope. And you can’t beat the price for what you are getting.
