Always loved Acogs, so was super curious about these. My one and only complaint is the eye relief. Something just feels off with it. Almost like you have to be off centered to get the whole sight picture. Other than that small detail, it seems rugged, walked it right in at 50yds, and it looks great!! Have put around 100 55grains down range and it’s held its zero so far!
Thumbs up
Amazing optic! I bore sighted the sight to my barrel and when I say it’s on point, it’s on point! Very easy install and use. Highly recommend this optic.
Great optic at a wonderful price. Fast to acquire sight picture. I have 8 Saturn optics and will get more. You get a lot of bang for your buck with Cosmic Tactical Optics
Figment to the quick release mount was great. The latch on the mount is a bit loose but no issues securing the optic to my rifle! I love the clarity and overall look of the Saturn!
The biggest complaint I have is, the reticle is way left, the first one I ordered had to send back, because when sighted in the reticle was way left, and a weird D shaped image on the right like a refraction, the replacement came, a bit better but reticle still on the left side quiet a bit, love how clear it is and just don’t want to wait for another one, thinking of getting a trijicon acog now instead
I mounted the Mercury to my Springfield Echelon. This is the red dot that moves in, raids your fridge, and still pays rent on time. It bolted onto my Echelon as it came in the same box. It wakes up when you move the gun, then takes a power nap after 5 minutes so you don’t have to babysit batteries. This is basically the only roommate you trust with your carry gun. 5 Stars
Wow!!! I didn't spect this item to work well, just because it's my first time buying. Absolutely, I recommend it!!!
With this optic, you can not miss. It is extremely fast to get on target. Quality optic at a good price. Lots of bang for your buck. I have 6 and will buy more. It is great for CQB and distance. I got 1 for my 308 also. Highly recommend.
love it
Negatives First, Then Positives; - Pretty lame that it doesn’t come with the silicon covers. Having to pay about $30 extra the keep the lens of a $300 optic clean is quite annoying - Point of aim was so far off out of the box that rounds were hitting 6 feet right at 15 yards - Awful eye relief, unusable when more than 5 inches from your face - “Assembled in Texas”, but definitely Chinese parts - Now that it is finally sighted in, it has managed to hold its zero after 265 rounds. Seems stable and tight, so far seems like solid construction - Top mounted picatinny will be great for adding a dot on top - Does the job I need it to and doesn’t cost an arm and a leg to do it
Got one for both my 5.56 ars Love them both. If I need another 4x32 I know right where to go
Very nice setup. Good clear vision.
I love the mercury, it just works, and works well. it definately has the best glass in this price point.
Unfortunately my Scope came with a deep scratch on it. I emailed customer support to exchange it for another one, but I haven't heard back from them yet. Update...customer service reached out to me and they are replacing my scope. These guys are Awesome! Not only do they have a great product, they also have Outstanding customer service!
these are awesome. I have purchased 4 and will probably end up with a few more.
4.9 realistically Great scope Eye relief…..if there is a way to fix that to get it to 3.5 inches (lol) while maintaining its affordability we are cooking
tjos is my second one. the first went on my wife's M&P, she loved it so much, that I got one for myself. I removed the mecanik sight and installed the mercury. I also have another one coming for my echelon.
Just mounted. Still need to sight in.
Very nice , I was surprised it was exactly what you said it would be
I would like to send it back but that seems to be an impossible task. The eye relief is super short and the bullet drop compensator seems to be misaligned. The chevron is too small and it can not be shot with both eyes open for short/quick target acquisition. It looks cool but I have a hard time believing it is an actual optic for real guns and not an airsoft knock off
The scope itself is OK. The GOOD: It holds Zero well. I like the green A apex it really helps me get in tight. It's bright and all when it's light out. Shipping was fast. The Bad: It should be 5X and the eye relief is terrible. I took a couple bumps to the nose when shooting the AR15. It arrived poorly packaged in a white bag type package. UPS had somehow (as always) mishandled it and the bag was opened and the silicone end caps and the diffuser I bought with it were missing. Customer service took days to respond. I finally did get the missing items. (good job) It begs the question "Would I buy another" The answer is NO to possibly. If it stays the way it is now I would not purchase another. If as a bare minimum they made the eye relief 2X better AND included at the bare minimum the silicone covers then I would definitely consider purchasing another for my other platforms. That is a big IF though. Final thoughts. I have astigmatism and the fiberoptic A Apex is the way to go with an etched scope. I can see everything clearly. If I could put my eye 3-4 inches back and see clearly then Yes I would consider another and add a 5X version as well. Just one users opinion.
Amazing optic! I absolutely love it and a great price point. I ordered 2 accidentally, and emailed Cosmic to help resolve the issue. They responded in a timely manner and resolved it flawlessly. Thank you guys!
An awesome scope for the money ! Do get one ! Aesthetic looking, functional, and just sexy.
great product. looks great on my Ruger Precision rifle.
Loved my first Saturn (FDE) so much, had to get a second one in black and pair it with the top mounted Mercury. Waiting for a FDE Mercury to come out.
Everything bolted up nice and secured. Scope covers fir perfect
Easy to zero, fast getting on target and at 300 yards 6” round plates fly. 5.56 10.5’ barrel! LOVE IT!!!!!!
Exactly what I thought it would be. Awesome! I also bought a holosun for comparison. I returned the holosun. It was almost half the price with more features. It’s also made in USA!
Love the red optics. Had to use the riser. Simple addition to the rail and scope. Bore sighted scope. Hitting target nicely. Will be getting a red dot soon for the top rail.
The scope was easy to put on and arrived with no marks on it.
Excellent well built optic. Easy to mount and holds zero perfect on my Jakl 5.56. Will recommend to the gentleman down at the range!
Well I love how it sits and looks, went out to the range yesterday to get it sighted in And the green dot through the fiber optic cable quit working Will not come back So I just plan on buying a red dot for sights Outside of that I love the optic.
not to bad at all.
great optic, great communication with company, hits way above its price point. already bought another and possibly will get a third one.
This makes it so convenient instantly just pop on your optic or take it off if you want to use iron sights I love it.
So far so good. Easy install on my M&P 10 2.0 and it looks awesome on the gun. My only complaint is that the green dot could be a little brighter but it would not keep me from buying another.
I absolutely love it, an unorthodox shaped scope for an unorthodox shaped rifle. I couldn't be happier and the picture is clear as all get out.
Love it. Very quick site acquisition.
It looks insane, also the glass is wildly clear!!
