  • First Impressions
**This is a first impression review only** I am happy so far with the perceived quality of the scope after unboxing. The reason I knocked off 2 stars is because the green light illumination seems to favor one side of the crosshair, where the red light illuminates the whole reticle. I'm sure this is a quality control issue, and not an overall issue with the quality of the scope itself. Luckily, I don't see myself using the green light much, just a personal preference. The second reason is the included flip caps; while I appreciate the sentiment, they hinder the use of the focus cap. Also, the smaller flip cap does not fit all the way onto the tube without trimming some of the rubber off (it hangs off the end if you don't trim it, causing the cap to bend when trying to flip it open - see attached photo). I haven't got to put it to true use/testing yet, but I will update this review after putting a few hundred rounds through it. If I don't forget.. I want to give 3.5 stars as my official review. For the price, I don't really see how this scope could be beat. ... show more

  • Decent optic, but FDE tone is off
I bought this in FDE and it's color is a stark contrast compared to other common FDE tones. The included cantilever mount is right, but the optic itself is off. For a better sense of the FDE tone, see the image in the description of the optic itself, not in the one in the sales photo (-1 star for misleading sales photo, leading to me needing to do more work). Haven't shot with this yet, but it seems like a decent optic from the bit of playing around I've done with it. ... show more

  • Excellent eye relief!
Color: Black
For the price point, this is a solid optic. I found it hard to believe that it has much better eye relief than optics I own that cost 8x to 10x the price. So far it holds zero and tracks well.

  • Really impressed
Color: Black
Found myself wanting to change my build, so I did some homework on YouTube and found this guy. The reviews seemed legit and made it sound like the best deal out there. They weren't lying. It came in packaged all nice and neat with some extra key wrenches, screws, batteries , cleaning cloth, manual, 2 nice flip-up lens caps, the mount and the scope. The build quality of the items included feel and look like top tier optic brands. Installation was a breeze and fired a few rounds with it on. I was blown away by how awesome this thing was! The magnification throw lever was my favorite feature with the illuminated reticle right behind it. The only thing to hinder if from being the best optic of all time would be that the illumation on the highest setting can't be seen during the day. It was meant for low light situations. Perfect for what I need. I will be ordering another one soon for my wife's rifle. ... show more

  • Clear. Rugged. Light
Color: Black
If you spend twice as much on your scope as you spend on the rifle, you probably can find some esoteric negative about this product. But if you seek reliable function an quality for nottabankbustingprice, these are real nice scopes. And not necessary to store with the family jewels. I bought another one. ... show more

  • Illumination dial in advertisement is not on the bottom.
Color: Black
This scope is well made and the glass is very clear. Side Note: if you want to check the clarity of any optic and you have a HDTV look at the television from about ten feet away and good glass will make the picture even clearer. Now, the mount is sturdy but the advertised scope has the illumination dial on the bottom, that’s why I purchased this one instead of the $79 optic. When I unboxed this optic the dial was on top like the other scope. This may be minor to some but that slight obstruction of view can cause you misidentify something or someone at a distance while trying to acquire a target. This is reason for the four stars. Misleading advertisement. ... show more

  • Good value for a 22, but not bigger.
Color: Black
I’m a newbie on the topic, but this is Not bad for the money, but not awesome either. Good for a trainer 22, but not recommended for something more serious. It’s in the “budget minded“ range for price and performance. if you’re a scope connoisseur you probably know this isn’t for you, but if you want a backup to go on a trainer, then it is fine. ... show more
