  • Top quality at a fair price!
Style: Circle Dot Reticle
I love it! Its built well, solid, no flaws. It was heavier than I imagined, but its very sturdy and that's what I was looking for. The scope is crystal clear with a decent eye relief. The reticle is clear and the lights work perfectly, amd are plenty bright/dim enough for any occasion. On a Milspec AR the scope "co-witnesses" the A2 front post (which doesn't work like a red dot because of the magnification) so I purchased the 7 slot monstrum quick Detatch adjustable riser for about 18$ and that is perfect for this scope and puts it at a comfortable eye level on its lowest setting but still keeps the sight clear of the front post. I haven't had the chance to go to the range but I'm sure it will have no problems as the construction is solid and its not a "cheep/crappy" sight, this thing feels like quality, on par with the major (expensive) brands. My only complain is that you can't get a cover for the lenses, but you don't really need them. it also comes with batteries installed plus replacements, along with a lense cleaning cloth. Hope this info helps some potential buyers, I recommend this sight without a doubt! Top quality at a fair price, no corners cut. ... show more

  • Nice scope for the price
Style: Circle Dot Reticle
Ordered this as a slightly magnified alternative to my red dot. Image is clear, reticle lighting is nice, it has held zero with no issues so far (a couple of trips to the range), and seems pretty well made. Depending on your application…I would also recommend ordering a riser for it. I did and it sits nicely on my rifle. The eye relief is pretty good as long as your application doesn’t kick super hard. So far so good! I’d definitely recommend this for smaller rifle applications. ... show more

  • Great performance for price.
Style: Circle Dot Reticle
5 stars for price and performance. It's crystal clear, the etched reticle is easy to see both illuminated and turned off. The magnification is exactly what I need for 25 to 50 yards. Holds zero very well. So well in fact that after I accidentally dropped it from about 5 feet and it's still zeroed after hitting the concrete. The only con I can find is the weight, it's heavy, all metal shell is sturdy yet not too heavy as to throw off the balance of the gun. The eye relief is a little too short for my far sighted eyes at times but I have this issue with almost every optic I have ever used. Overall great product for the price. ... show more

  • Best bang for your buck
Style: Circle Dot Reticle
This is the best budget prism sight ever. Easy to zero easy adjust brightness and zoom. Hold zero no problem! Have it on my truck gun it’s been mortared a few times and have shot over 4K rounds with the sight on and it’s never gone off zero. I’ve had it for over a year and it’s yet to run out of battery life. If you’re looking for the best scope/sight for under 200$ then this is what you need!! I highly recommend this product and there brand ... show more

  • Kinda Meh
Style: Circle Dot Reticle
Good: Nice, clear optic. Helps with astigmatism. Bad: The bars to engage the picatinny rail are not drilled at the same level...so...only one actually locks the mount to the rail? WHY? Eyebox is limiting. Have to be much closer to this scope than my others of the same magnification. Which is particularly weird, given that it's eye relief is listed as further than the other. Also can't move my head very much, or it's immediate shadows. And no where in the specs on the listing, do they mention height to center of the optic. It looks low - it isn't. Really no idea why that information wouldn't be listed, since it's one of the critical points to a scope - will it clear BUIS, is it too far above bore line/rail, etc? So, meh. ... show more

  • Great Value Circle Dot 3X Scope
Style: Circle Dot Reticle
Great circle dot 3x scope. Works lit or unlit (adjustable brightness too). Easy to zero and holds zero well. Is a bit heavy but overall a great value, especially at this price point.

  • A great little* optic for folks with astigmatism
Style: Circle Dot Reticle
I slapped this bad boy on my homebrew rifle and it works like a charm, the reticle can be as bright as you would like it, and lasts quite a while when accidentally left on while in storage. I put a few rounds through it, jostled it around some (threw it at a tree), and it stayed true as ever. If weight is of concern for your build, this optic may not be right for you, but I like a bit of heft on my rifle, so it is a welcome addition. If paired with a nice set of canted iron sights, you have a trustworthy and aesthetically pleasing gun. ... show more
