Fiber Optic 1×30 ACOG Knock Off Review


Earlier this year I posted about this 1×30 Fiber Optic Green Dot sight that sells for between $60 and $80 over on Amazon. I like the idea of an optic that doesn’t need batteries and I’ve always wanted an ACOG, but could never afford one. So I decided to give this Amazon copy cat a try. Let me start by saying I’m from the camp that says you should always try to buy the best you can afford, and for my .223/5.56 ARs I always do. Since this is planned for use with my .22lr S&W M&P 15-22 I’ll break that cardinal rule this time.


According to the Amazon product page the brand nameless optic, which they call a “1×30 True Fiber Optic Green dot sight sighting system”, is 6MOA, has a 6061 T6 aircraft grade body, Japanese style of manufacture multi-coated optics (whatever that means), 1x Objective lens with a 30mm recticle and a field of view of 54ft at 100 yard eye relief. Oh and if you haven’t guessed by now, it’s definetly made in China. What makes this optic interesting is the fiber optic illumination that doesn’t require any batteries. However you can power the dot with a back-up battery in case you find yourself in a night time spec-ops mission (plinking with your .22lr in the dark). The mount it comes with is pretty sturdy, it held up well after the thousand rounds or so we shot during the duration of our review. There’s room for Magpul sights underneath, I like to mount my optics as far forward as possible (see picture above) so clearance wasn’t an issue for me at all.

Sighting it in was easy and straight forward enough. I’ve used it on my 15-22 for the past few months, and it’s held zero just fine. Now I didn’t drop my rifle or bang it around, but after around a thousand rounds it’s still on point. In the picture above you can see the button to power the optic in low light conditions, it uses a few watch batteries that were included. Out in the daylight the green dot was nice and bright. The dot was a little difficult to spot if you were using it in the shade and your target was out in the daylight, i.e. at an outdoor range with covered benches. Just hit the button beneath the recticle and the problem is solved.

Because this is a budget priced made in China optic I actually bought two of them to see how consistent the quality was. With these cheapo Chinese accessories it’s not uncommon to get a dud. Both worked fine, held zero and functioned pretty much exactly the same. The only variation I noticed was the lens color of the optics, as you can see in the picture above they’ve obviously different.


I am actually quite impressed with this optic, on an airsoft or .22lr range toy or trainer rifle it would serve you well. On a real deal .223/5.56 AR-15 I wouldn’t bet my life on it however. Not everyone can afford a $1000+ ACOG, but if you want an affordable fiber optic sight this budget friendly option is a decent choice at between $60 and $75 shipped on Amazon.

  1. I’ve been running one on my AR. While I was on a Seal team we ran the aimpoint. Pretty good little sight. It holds zero and is accurate for the price you can’t beat it.

  2. I’ve had terrible luck with Docter and Trijicon miniature Red Dot sights with Aliexpress. The lenses would warp/distort the field of view, and create a red dot that would be 40moa (exaggeration) in size.

    This gives me hope!
