I got this last weekend and just returned from the 50 yard 22LR range with good results. At 25 yards, the initial rounds were 4 inches low and 4 inches left, but after dialing up and right the appropriate number of clicks, bulls-eye! With 1/8 moa per click this required nearly a 1.5 rotation of each adjuster but after landing close, the sighting adjustments were responsive. At 40 power I can see exactly where they land. It comes with very tall scope rings that are caliper type for a standard rail. They need to be on the tall side because the scope is quite large. Eye relief is what you expect and the focus knob is a used quite a bit as you change magnification. Glass is clear and the cross hairs are fine but that is appropriate for competitive shooting. This is a non-illuminated daytime scope that is best for benchrest shooting. So far, the bang for the buck is on-target.

I initially purchased this for bench rest air gun competitions. Unfortunately, haven't able to use it much because of issues with the air gun I ordered. I did get to try it on two other air guns and it worked really well. I was able to mount it, zero it, and site in a gun in with about 25 pellets. It seems pretty accurate for the price, I might even order another in the future. The one downside was that one of the mounting rings seems a bit to small, it doesn't complete encompass the scope

First off great price for the quality. Image was clear at 40X I had a small dark ring but just a small adjustment of the parallax and it was gone. Second for the one complaining about zeroing issues this scope moves poi 1/8 inch at 100 yards at 50 it's 1/16th simple math. Also when torquing go in a criss-cross patern with both rings. Snug them then torque to 25 inch pounds.

Please make sure you check the white sealing tape BEFORE you attempt to open the scope packaged box; mine was previously opened with broken seals (left and right) of the box alerting me that it had been opened and NOT a NEW item. There are so many things wrong with this inexpensive scope at different levels: as many others have said, this SFP reticle is way too thin and IMPOSSIBLE to see on cloudy days or viewing your target at less than bright daylight. It would go a long way if the reticle was illuminated but because of its price point they elected to keep it on the cheap and no illumination. The 50mm objective lens is too small for 40x zoom and coupled with a 1 inch tube there is not enough light coming through at the higher magnification range; this is one very dark scope. The reticle has been manufactured for 25 meter bench-rest shooting but most bench-rest shooting is done at 50 yards (meters) so the reticle is not very useful beyond 25 meters.

I was looking for a higher power scope for 50yrd benchrest and this fit the bill perfectly. Overall it is a nice scope with clear bright glass and fine crosshairs with a small center dot that is perfect for this. It has locking turrets and each click is sharp and accurate. The side parallax focus works well and is a must for me and the adjustable eye piece helps to clear-up the crosshairs focus. It comes with everything you need from scope mounts to scope caps and other goodies. Overall it was what I needed.

I have know purchased two of these scopes. The adjustable power works well and side focus is a must. These scopes are for target shooting and they work well for this at a great price. I use both of these on CZ 452's in 22lr and they work great. The center dot is really small but if shooting targets you will love just how small it is allowing you to still see the bulls eye around the dot and not just cover it up so you guess that you are still on it. I would recommend these to anyone who wants to get into target shooting as it is the best entry price you will find.

Good turrets, really like the reticle. Very touchy parallax adjustment. The down side is the scope isn't very clear. Its a little cloudy. Cheap, you get what you pay for. Spend a little more and get a discovery optics. Better made and a way clearer scope.
