  • Replacement Item Review
Was fantastic the first 4 days of use and then would not hold it's zero. " Could not get it back zeroed in." This was what I wanted while it worked just didn't last long at all. I mounted the replacement this morning. First thing I noticed was the same issue with the scope mount. It slips on the dovetail grooves. I cured that with some clear 2 sided tape. Last time it slipped back and sliced off the stop pin on my gun and the stop pin on the mount would not work because of the placement of the pin, " to far forward on the mount ". I fired off 25 pellets this morning and all seems well so far. Am using the scope on a " Beeman Teton .22 cal. Gas Ram ". Will update in 1 week from today, 7-19-18. 7/29/18 Things are working great! Am still having an issue with the mount slipping, But, Hammer's is working with me on that at no cost to me! The scope is holding its zero. Would recommend this scope to anyone with a springer air gun! And it has a life time warranty. ... show more

  • It's huge, and a little heavy
Seriously, if you are using a break barrel pellet rifle you seriously need to make some measurements before ordering. I had two and three quarter of an inch clearance left on my Hatsan 95 Combo. The scope was actually a little too far forward on the mono rail for my rifle, so had had to back the scope up nearly a half inch on the mount. Of course I had to break out the levels and that's really annoying. The capped toolless turrets are great for making quick adjustments on the bench. The optics are not the best quality but that doesn't mean this isn't the best scope I have owned. And that 40mm aperture really brightens up the shadows. This might be a brand I haven't heard of before, and having it mounted on a break barrel pellet rifle is probably the worst thing you can do to a scope. But I am going to have a lot of fun seeing how long I can use it before it needs to be replaced ... show more

  • Tough
These can handle nasty springer recoil and will make even cheap springers shoot much better groups.

  • Returned - Wandering ZERO: I'll Try Another One - If No Joy - Return That One Too
This scope has great clarity and a very nice reticle. It worked great for 25 - 30 shots (see photographs). Then the shots began wander all over the place. The first sighting in group is circled with a dime (to the left of the right target). The scope was adjusted and were hitting on the mark. In the second photograph the right target contains 8 initial shots. Another 5 shots were fired through the same impact points. This is not about my marksmanship. The rifle was steadied and properly supported for all of these rounds. The next day, just to be sure several rounds were fired at the target on the left. After the first shot they were all over the place. ... show more

  • Lens may come loose…
The lens that you initially look through came loose after 100 shots or so. It’s mounted on a stoeger s8000 etac nitro piston rifle which shouldn’t cause that much damage to the scope versus a spring air rifle. The magnification changes and so does the point of impact. Once I glued the lens in place, (out of warranty), it seemed to fix the problem. Not an awful product for less than 100$ but knowing these things may have made me buy something else. This being said, it’s still mounted on the rifle currently and seems to be holding a decent zero. ... show more

  • Handles nitro piston airgun shock.
It seems to be holding up again the shock of a nitro piston air gun. This double shock kills many scopes.

  • Best airgun scope I could find under 100
Replacement scope on an air rifle, there is some double sided tape inside the scope rings I would advise you to remove for a more solid scope mount, optic is very crisp, decent low light visibility, All focal rings move smoothly, adjustment detents are a bit spongy but acceptable. Overall very happy with the product. ... show more
