The term refers to the position of the scope reticle in relation to the magnification lens. In FFP scopes, the reticle is located to the front of the magnification lens - the first focal plane. The size of the reticle grows or shrinks in relation to the magnification. All adjustment assemblies are composed of solid brass which make them function smoother and more precise than before. Milled from a solid piece of 6061 aircraft grade aluminum to ensure scope rigidity and strength. This scope has a 1/4 MOA/click windage & elevation adjustments with zero reset and turret locks to prevent slippage.

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.

Replaced on old school Weaver style 4x scope on my 1903 30.06. Holds zero well. Clear glass and nice site picture with the first focal plane reticle. Head and shoulders better than high end but old 4x scope (quality of glass, crispness of image, and brightness). Love that it comes with a ARD (anti reflective device) at no extra cost. Mine was actually missing when I received my scope, contacted Monstrum, shipped out day after providing proof of purchase, about a week, start to finish. Mounting rings also seem to be great and are included as well. Nice quality and heft to them etc… A lot of bang for your buck here!

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.

I bought this scope for a .308 that I am using for wolf, coyote and hog which have become a pain on my farm and I needed an economic scope that allows me to extend my range a bit. So far, I’m very impressed although the scope isn’t perfect (but fantastic for the price). The construction of the scope is solid. Carrying on a sling, it’s been bumped around on the Ranger driving around the property and brushed on tree limbs, etc and it’s been fine but here’s a minor flaw. The lens covers don’t stay on very well, particularly the front one. For me, I had to really dial out for eye relief and the resulting distance from the lens to the body of the scope creates a gap that doesn’t allow the lens cover to stay on (I’ve taped mine to ensure it stays). Using the scope is intuitive so sighting was pain free and using the field is aided by markings that remind you which direction is up, down, left and right which is a nice little feature. As others have remarked, parallax isn’t perfect and the scope rings are a little high but I purchased a cheek rest which helped while adding a little comfort. The AO adjustability has proven useful and the ability to zero out the turrets is great. I have other FFP scopes (Bushnell) and have grown to like them so I was pleased to find this feature here. The AO combined with clear holdover points on the illuminated reticle are great features at this price point and the 2032 button battery is common to my other scopes so I like having one battery that suites multiple scopes. Overall, I’m very impressed with the Monstrum G3. It’s not perfect but a great scope for the money.

Update: I emailed Monstrum about the adjustment issues and they immediately replaced the scope! Box drill is now spot on. I'm more than 500 rounds with it and the only thing that could make me happier would be a different reticle (I'm still not a fan of a dot at the center for long range applications). I still have the same setup and love it. The biggest factor when it comes to accuracy is now me. Original: I purchased this scope because I liked my G2. Everything is as advertised and I’m pretty happy. I’m not rating 5 stars (yet), because I’m not the happiest with the reticle and there appears to be greater shifts in impact than what should be predicted with the windage and elevation adjustments. A plus at this time is that with a 20 MOA base there is 56 MOA of available elevation adjustment up from my 100 yard zero. This gives me adjustment to 1200 yards with 308WIN according to my ballistic calculator. Test 1 - Fit & Finish: Good overall, as I have come to expect. Sturdy, smooth controls that actually feel a little better than my G2. Windage has 46 MOA of adjustment and elevation has 68 MOA of adjustment. The stops on these are not what feels like a hard stop. More like they get tight at the end. I have not wanted to crank hard on them to see if they will go any farther. On 6x there is a shadow that presents on the edge of the field of view at the far limits of adjustment that clears up as the reticle is moved toward the center of the mechanical range. This shadow is not seen at higher powers. The kill-flash has a tighter honeycomb than the one that came with the G2. This first focal plane reticle is disappointment at the moment. The G2 has nice fine lines that cross with fine marks for single MOA for elevation and every two MOA for windage. This G3 reticle has thicker lines with dot marks every MOA that stop just before the cross with a wide 1/2 MOA dot in the center. This dot is big enough to obscure longer range targets (1/2 MOA is roughly 5” at 1000 yards). Not what I was hoping for in a long range scope. Test 2 - Reticle Allignment and Zero: Using a plumb line, the reticle appears well aligned to the scope body with no appreciable deviation. Predictable adjustment to attain zero that has held for 60 rounds of 308WIN so far. Test 3 - Box Drill: Scope predictability moves point of impact with windage and elevation adjustments and returns to zero. The adjustments appear to move more than the 1/4 MOA per click. Adjustment 12 MOA up from zero resulted in a 14” shift in impact at 103 yards and adjusting 12 MOA down from zero and at the limit of adjustment (scope mounted on a 20 MOA base) moved impact 13.5”. Current setup: Mounted on an AR-10 variant chambered in .308 WIN, UTG 13 space 20 MOA base, Vortex low rise rings, Monstrum rubberized lens caps.

So far, I have a good zero that doesn't move. The glass is clear and bright. I like the way the turrets lock too. What else can you ask for? Winchester 300 mag

First, I got the G2. The button switch wouldn't light up the reticle consistently. So I returned it and got a G3 instead. It arrived with some sort of bubbles on an internal lens somewhere. These were especially visible when the reticle is illuminated. So I returned it too, and finally I got what everyone else was describing: sharp images, crisp dials, solid construction, etc. The "cons" are few, and easily mitigated: * The scope mounts are tall, so I got a set of 0.85 inch mounts that work well. * Both the reticle brightness and the parallax knobs are stiff, but not stupidly so. * My biggest gripe is that I'm unable to focus the reticle when illuminated. Granted, my eyesight needs some correction, but I am able to focus the reticle when it's _not_ illuminated. I get close to focusing it, but the end of the range of the focus adjustment ring leaves it a bit blurry. I'm able to differentiate the larger graduations from the smaller ones, but each graduation is not a fine line. Again, this is _only_ when the reticle is illuminated, so this is not a problem for me since I'm not going to be making sub-moa adjustments at night. * The quality assurance department is letting more defective items out the door than appropriate. Again, I had to return two scopes to get a good one. So if you get a "bad" scope, keep exchanging it until you get a good one. Took me three tries, but I'm very happy that I got this.

This is my second Monstrum scope. Typically they make a quality product for the price point. This scope should be sent with a pair of Channel Locks pliers to turn AO adjustment knob. Thought ok... its new so might be tight. After working the AO knob a few times my fingers hurt because its so tight. Really tight almost impossible to adjust. I worryed I was going to snap it off. Other reviews have noted this problem with this scope model. The other con... The illumination brightness adjustment is piggybacked on the AO adjustment makes it difficult to turn one without grabbing the other. Not user friendly, bad design. The battery access cover has large ridges and can be removed without a screwdriver or coin, however adjusting the illumination brightness setting tends to unscrew the cover. Another poor idea. Sending it back.
