  • I had my doubts but....
Well I got it for a .22 Ruger carbine. It really clear, crisp lens are great. If I thought that this would.hold up to recoil I would put one on one.of my AR platforms with QD mount. (which I bought separately even though the FDE one comes with a black scope mount. now they are both FDE. I have a real big scope for it just in case I want to go back to goofing around past 100 yards. should have got the 1-6. the edge to edge clarity (sweet spot in middle of lens) is great. almost all the way to the very edge. and even then it's just about as good as any high dollar scope. the o ly con is the FDE colors don't match and both the scope and the mount are theirs. the MX-1 reticle is great! the center dot is less.than 1 moa. and that's even better. this is a great scope for the money and if it's on sale father's day maybe I'll grab the 1-6 just to have and try out. as a spare. they could change the mount tp QD in the box and tack.on 5.00..lol ... show more

  • Perfect starter optic
Color: Black Style: MX1 Reticle
This optic works extremely well for someone on a budget. Great for close quarters and mid range shooting, class is clear and easy to read, adjustment knobs are easy to set and zero and if zeroed properly and mounted properly is a fine piece of equipment

  • Decent for a cheapo
Color: Black Style: MX1 Reticle
I really don’t have many complaints about this scope. It’s cheap, has pretty clear glass, has held zero, feels solid. My biggest complaint is really the weight. It’s a chunk for its size.

  • Definitely a must try
Color: Black Style: MX1 Reticle
This LPVO is definitely a must try, I know for a $100 optic it can definitely be skeptical to order, It was for me but it’s a nice optic for the price, it’s got some good weight but not to much, the clarity of the optic through the entire zoom is really nice. The zoom isn’t to tough to manage at all the only thing that has a cheap feel to me is toggling through the brightness settings. But I won’t use that to much so it still gets a 5 star out of me, if it doesn’t hold up on my 300blk I’ll be back to update. But so far I definitely recommend trying this scope out. ***Update*** I now have 300+ rounds of 300blk and it’s held zero perfectly. ... show more

  • Quality optic
Color: Black Style: MX1 Reticle
This little 1-4x optic is fantastic. Well made, sturdy, both the optic and the bracket that comes with it. Holds zero perfectly on an old 30 cal M1 carbine. I was sort of regretting the purchase until I got it and realized the quality of its construction far exceeds its price. Then when I actually put rounds down range I couldn’t believe it. How can this little LPVO that in my opinion compares favorably against the big brand names of similar optics be so inexpensive. Of course I’m just plinking and playing around but that’s probably what most of us are doing. Hopefully the brand will stay priced as they are because once they starts getting recognized, the prices will certainly go up. ... show more

  • Piece of Junk
Color: Black Style: MX1 Reticle
I put this scope on a .17HMR. Started at 50 yards. Scope was on the paper. I started dialing it in and got it very close. Needed 1 more click to dead zero. I made that 1 click and went completely off the paper. Put up a new target and shot 5 rounds nothing hit the 12 inch target I put up. A that point I gave up. Would not recommend or buy again. I'll put my old Tasco on and not worry about it. ... show more

  • terrible reticle
Color: Black Style: MX1 Reticle
Seems decent. Reticle is probably the worst I've seen. Don't know why they chose a box for a reticle when normal crosshairs would do. Also, the 20MM lens seems small. I would skip this and get something else. Price isn't too bad, but this scope is not what I was expecting.
