  • Solid scope, great price point.
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. ... show more

  • Great scope for the price
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 ... show more

  • Clear and crisp
Clear optics and crisp adjustments. Hard to beat for the money. Very fine crosshair and thats OK since this is a target scope and not meant for hunting in lower light conditions. Had a chance to shoot with this scope. Adjustments tracker true and straight. The fine dot and crosshair take a little to get used to but are perfect for target shooting. It focuses down to 20 yards on 40x and is crystal clear. My new favorite scope. ... show more

  • Buyer Beware!
I mounted it on my 10/22 and tried to sight in using CCI Std Velo at 50 yards. Starting at the presumed factory Zero, it was hitting 17 inches below the aim point. After 3.2 up revolutions of the top turret, still 4.5 inches below the aim point. Obviously an internal issue. The image quality was decent on 40x, however the eye box and relief was difficult at any focal range. Returned ... show more

  • Nice Scope!
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. ... show more

  • Biggest bang for the buck for competition target shooting
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. ... show more
