Features
- Open reflex sight for rapid target acquisition of close range targets out to 100+ yards. Open reflex sights offer better peripheral vision and greater situational awareness than enclosed tube red dots.
- Offered in two different parallax free reticle configurations: circle cross reticle with a 2 MOA center dot and a multi-mode reticle with three selectable reticle options. Electronically controlled illumination with multiple levels of intensity up to daylight bright.
- The Ares Red Dot comes with a custom optical system with minimal power draw and Shake Awake motion sensing technology. The dot will automatically shut off after one hour and re-activate instantly upon movement, providing tens of thousands of hours of battery life on a single battery, up to 10 times longer than LED powered red dots.
- Integrated picatinny recoil lugs compatible with picatinny mounting platforms. For rifles and long guns. Not for use with pistols or handguns.
- All Monstrum products are backed by a lifetime guarantee.

Style: Circle Cross Reticle
I absolutely love the Monstrum Ares V2. The clarity is excellent, the construction is solid, and the overall performance far exceeds what you'd expect at this price point. It feels rugged and dependable, with smooth adjustments and crisp, repeatable turrets. The illuminated reticle is clean and easy to use in all lighting conditions, and the eye relief is generous enough to stay comfortable during extended shooting sessions. Zeroing it was simple, and it has held zero perfectly ever since. Honestly, this optic delivers the kind of quality and functionality you'd expect from a much more expensive scope. If you're looking for a reliable, durable, and feature-rich LPVO without breaking the bank, the Ares V2 is a fantastic choice. I couldn’t be happier with it.

Update, Seller responded extremely quick and sent replacement within 48 hours. It works beautifully. Just left the range. Was easy to zero in, seems to hold zero great. Very well made and sturdy. Red dot is nice and bright. Actually blew my expectations really. Can't beat it for the price honestly. Easy to install. Comes with all that you need. If you want a nice affordable red dot this is the one. Definitely going to be checking out some of the other monstrum products for sure. I wanted to like this red dot. Felt well constructed. Fit it nicely on my 9mm carbine. But every few shots it powers off. Changed the battery. Did not help. Just keeps shutting off. Not to mention i can't get it to hold zero when it is actually powered on. Im going to try one more time. Got a whole new battery. If that doesn't work I will send it back. No point in having it if it keeps randomly turning on and off every few shots. Update, Seller contacted me and has been super helpful and fast responses. Getting the broke one replaced. I will update after I check that.

I spent extra for the multi reticle version but cannot figure out how to change the reticle. So if anyone has figured that out, let me know. Other than that, it's a decent sight that's holding a good zero.

This red dot for the money is very well made! I have 5 monstrum optics of all sorts, this is my second one of these, literally best bang for your buck! I've got one a 12 gauge shotgun, has stayed zero even after 800 rounds! You won't be disappointed!

Bottom line first: If you want a massive sight picture for $35, this punches way above its price class. Just be aware of the edge-parallax quirk and plan on re-zeroing if you’re putting it on a thumper. What’s good Huge viewing window – Fast acquisition for both-eyes-open. It really makes other red dot sights feel like peeping through a keyhole. The reticle is pretty crisp. Adjusting elevation and windage has those reassuring clicks you'd expect from something almost 10x the cost - this is a welcome surprise at this price point. It has shake awake. Parallax “mostly” corrected – with the nice big window, you will drift off towards the far edges. Price – You literally can’t buy a decent mount for what this whole optic costs. What’s not Edge parallax – The far edges on each side start to wander. .. and that's it really Recoil tolerance TBD – I’m slapping it on something that kicks a bit and will update this if/when it loses zero.

This thing ironically had more positive reviews than most cheap dots on Amazon, so I thought I'd hit the jackpot at the price. And yes, I've bought tons of other cheap optics on here so I know what to expect. And many of them are great. This was complete garbage on every level. It seemed good at first, super weighty, quality seemed solid, I thought I had scored. It only went downhill from there... - included battery dead - no hex tool for the picatinny screws - won't even mount straight, looks horrible at a super noticable angle - battery compartment lid barely moved and creaked like it was a hundred years old and rusted shut - picatinny screws are as soft as mashed potatoes and stripped after literally one normal tightening - shake awake worked literally 3 times then completely died so long story short, a completely trash, unfunctional, pointless paperweight. of all the budget dots i've bought on Amazon (CVLife always delivers) this is hands-down the worst. i wouldn't touch this again with a ten-foot pole.

For the price, it's fantastic. I expected a super cheap product but it's solid and holds up to daylight range use. It looks very modern and has that tacticool appeal. The reticle is very bright. If you have a lot of weapons and you want a dot for a fun gun this will do. If you want to spend more the multi reticle version would be a good choice, too.
