Question: Can I use a magnifier with this 1x scope?
Document: For the bang for the buck this thing works great.I was hitting about a 3-4 inch spread on a splatter target from 100 yards with the 3x magnifier on with my .223 AR. Very happy with that overall.The two minuses that I would give this knock off scope is that the dot is a bit big, and the left right and up down is not clear on the dials you adjust with.
This scope is garbage. Even though it's a 1x scope, it's VERY dim. The green dot is invisible unless it's in direct sunlight. The body was manufactured so poorly that it looked used. Normally, you'd want to get a 1x scope for quick target acquisition, but view from this scope was so limited and so dim that it made this impossible.Do your shooting community a favor and don't buy this.
I've noticed that nearly every infantryman seems to have an Acog, likely Trijicon, on their M-16/M-4. Of course this makes me want one, but they're around $1,000. Kind of difficult to justify. An acog is usually 4x zoom, and has a bullet drop compensator reticule.This scope, coming in at under $80, is a 1x instead of a 4x, and has a green dot, instead of a BDC reticule.
So this is a huge advantage.While you get no magnification (you can always by a rail magnification system) on this 1x scope, the Japanese lens is beautiful. I've read some say that it's some division that makes lenses for carl zeiss optics, but can't confirm that. They reflect the reticule beautifully, and are tinted\treated for glare and mirroring reduction. They seem firm and well integrated.Not to mention the build! the aluminum casing seems top notch, feels tight, sturdy, and sealed.
I actually never had an opportunity to use this on my AR-15 because the windage and elevation screws were completely locked up. I could not make any adjustments at all to the sight to zero it.I'm giving it two stars because everything else worked fine. Amazon refunded my money for the defective scope.
Looked intact right out of the box. When you mount it on a gun and shoot for the first time don't count on it working. The internal parts of the scope are flimsy and will fall out of place the first time you use. But the biggest disappointment however is the seller. I can't go into details about that here. But what I can say is that if you have a problem with this product where it falls apart don't count on it ever getting resolved.
It sits great on the top rail at a good eye level.At first a was a bit disappointed with the "fiber optics" that the scope claims to use. I was inside in a half lighted room and could not see the dot very well. If you go outside in the sun or are in a well lite room, that dot pops clear as day. If you go into a dark room and kick on the back up battery, it pops really clearly again.
One caveat to keep in mind is that if you were in darkness and powered the reticle on it will light up the optical fiber and give away your position. A piece of standard black vinyl electrical tape will solve that problem. The most awesome feature of all is that I took my scope off to shoot irons sights and when I put it back on in the same notches it repeated without having to rezero! It is a CQB sight so don't pretend that you are going to use it for a sniper scope.
I bought this to use on a new build AR 15. The unit is nice, it holds zero pretty well. I was concerned about the size of the dot, however I had it on the range today shooting at 200m. I had no problem seeing the steel and hitting it. It's not as precise as a scope but it will get the job done. Not a bad buy for the money.I did contact the seller with a question when I got the sight, I was answered very promptly.
I was a little leery about buying this scope for my Spike's 5.56. I was wrong. This scope is really nice for the money. It mounts great and looks great on the gun. Took to the range and only took five shots to get in a good group. I know its no ACOG but I dont use this gun for tactical situations. I dont think it would hold up under hard use, but for range shooting and hunting close range it would be perfect. I would def. recommend.
