MonstrumMarksman G3 3X Micro Prism Scope | Electronic Button Control | Shake Awake Auto On

This sight is pretty awesome! I can really appreciate the fact that rarely would you need to power it on. So far I've only turned it on once, just to see if it worked. The reticle being etched in the glass is genius. I'm considering one of the other models for another rifles... So far, so good!

First it Monstrum customer service is amazing! I bought a PM3E 3x prism scope early March. Looked great zeroed great, after my 3rd trip to shoot I noticed a blemish on the prism inside the scope. Contacted monstrum explained the situation. I was offered half refund or free replacement with their paying the shipping. New scope within a week of shipping. Great product. Great customer service. They have way upped their game in the past couple of years. I look for these guys to be just like vortex in the coming years. Get in now while the price is still amazing. You’ll be kicking yourself in a few years when you see these on the shelves in your favorite gun store at triple the price they are now.

purchased for a 22lr AR type rifle. It works great. Clear, was easy to zero and well worth the price.

Arrived with a dead battery. I will have to check for a battery drain. This thing is way overbuilt. 2X the weight of a Primary Arms prism but also 1/4 the cost. Clear enough. I have it mounted on a S&W 15-22.

Does not zero….. spent about 3 hours at the range messing with it and could not get it to zero. I have several Monstrum optics and this is the first one I’ve had that does not work.

Can't afford n ACOG? Get this!

A good solid optic for the price.Simple controls. Press + or - to turn on, hold - to turn off, hold + to change color and increase/decrease illumination with +/- respectively. There are 11 illumination levels and brightness settings are saved to memory. Your optic will go into "sleep mode" after 10 minutes of no movement. It will fully shut down after 2 hours.Mounting is also very simple. Built in mounting system which mounts on picatinny style rails. A T15 torx wrench is needed for installation and it's included with the package. Documentation calls for hand tight and then a 1/4 turn or approximately 30 in-lbs.Sight adjustment is, again, simply done. It's 1/2 MOA windage and elevation adjustments which are located on top and side of the body. Top dial is for elevation and side dial is for windage. The documentation do give simple instructions on dialing in your sights which is helpful for any new shooters.Weight claims. I weighed it with my scale at 330g (11.6oz) but they claim it's 289g in the documents included. That's a substantial difference. The listing says it's 23% lighter than their previous generation prism scope and I assume they are talking about the Marksman G2 model. The Marksman G2 model is listed as 326g (11.5oz) on Amazon but 311g (11oz) on Monstrum's website. Either way, this one is heavier than both of those claims so obviously it's not 23% lighter based on those claims and what mine weighs.They claim this one is 27% shorter than previous generation models, again assuming G2 model, I have no idea how it stacks up because I do not own the G2 and they don't have a height measurement anywhere. They do have the G2 listed as 4" in length, and the G3 is listed as 4.2" in length. I measured the body of the G3 at exactly 4" but if you include the mount, it's roughly 4.2" so that's about right.Some pros:- Very solid build- Shake Awake- Prism type optic (helps with my astigmatism)- Etched circle dot reticle (works without batteries)- Water and fog proof- Red and green illumination- Full lifetime warranty (I have owned a handful of Monstrum optics, and I do have experience with their warranty process. They sent me a replacement scope with no questions asked.)Some cons:- Eye relief could be better- No caps for lenses- Listing/documentation seem to fudge some numbers a little.Overall, I really like it. I don't mind the weight but it is worth making a note of it. I gave it 4/5 stars for eye relief, no caps and misrepresenting the product specs.

A good mid-range scope fixed at 3x, which I feel is an ideal distance for me. I don't always want or need a long distance scope, although I do have added iron sights in case I'm shooting close up. The shake awake feature is great and hopefully becomes the norm. The reticle is always present even when turned off so that is a huge plus for me. It also looks cool but is slightly heavier than it looks- which can be attributed to the solid build quality.
