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.

  • Just do it
Solid red dot. Super clear glass, crisp dot, and the brightness settings cover everything from low light to bright sun without washing out. Mounts up tight and holds zero like a champ—no issues even after banging around a bit. The QD is a nice touch, makes it easy to swap setups. Honestly surprised at how good this thing is for the price. If you’re on the fence, just get it. Monstrum nailed it. ... show more

  • Problem fixed, great customer support. Nice affordable sight.
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. ... show more

  • Reasonable price, survives it purpose.
Quilty built, very impressed with construction, ordered second one for grandsons Ruger 10-22, mount does not fit factory rail that comes with 10-22, must purchase standard rail for 10-22, Monstrum offers 2 different styles must be purchased separately. Standard 2032 battery, came w/one installed & spare, shake awake works, I turn mine off when not in use (haul around in Kawasaki Mule) saves battery. ... show more

  • Not too bad!
Unsure of the durability or longevity at this time, but for the price point, it’s a pretty good addition to throw on a “backup” platform!

  • So far 5 stars!
Optic has a large view, and that is my first impression to give five stars. It’s great looking. Brightness on red dot is great. Mounted tightly to the picatinny rail. Came with two batteries, which is cool. Would have like a rubber cover! Will update once I zero it and see the optic in multiple lighting situations (only saw from inside the house so far). ... show more

  • I love this brand!
I haven’t had very few problems with Monstrum optics. One of their scopes with illuminated reticles wouldn’t light up, but I didn’t buy it for that reason, so I let it go. I have this one on a .450 Bushmaster, and used another on a .458 Socom and they handle the recoil well. Huge fan of this brand, and this optic performs great as well. ... show more
