    • Solved any issues I had with air rifles destroying my previous scopes
I took a chance on this with very little research and am pleased to say that this Hammers 3x-9x, with 40mm Adjustable Objective lens has not only resolved any issues I had with air rifles destroying my previous scopes, but is also quite accurate when using the AO correctly along with the fine focus eye relief. It's been holding zero ever since the initial phase of re-tightening the mounts a few time until its good and seated so screws aren't vibrating loose. I am hesitant to use threadlocking compound because I'd hate to deal with it later during any required disassembly. Glass is CLEAR and the turrets and aluminum cylinder are plenty stout. The AO has yardage marks from 5 to 100 (+ infinite max) and best I can tell, it does focus to the stated yard marks and reduces the parallax effect when aiming down range at distance. Absolutely worth the price paid! ... show more

    • Great pellet rifle scope
I was really surprised by the quality and durability of this scope !! It’s very accurate and easy to zero. I have it on my.22 caliber gas piston air rifle and after roughly 500 shots it is still dead on zero and no fogging. It really is a great scope for the money.

    • Update: Destroyed itself within 80 shots
UPDATE: Below is my original review. This summer I wasn't hitting my target and re-zero'd the scope. I found I was hitting about 6" low at 25 yards. I set zero, confirmed with a three shot group and the third shot was 6" low again. Scope will not hold zero and is junk. Recoil from a nitro piston .177 (Crosman F4) destroyed it well within 80 shots fire, probably closer to 50. Do not recommend. ORIGINAL REVIEW: So far so good. This scope replaced a very cheap scope that was included in the box for a big box store nitro piston air rifle. Amazingly that cheap scope lasted around 300 rounds before losing zero. First thing this scope is heavy. VERY heavy. If you are doing a light weight build or a hunting rifle and don’t want to tote a bunch of weight then this one might not be for you. Mine is for plinking and pests so the weight doesn’t bother me. Adjustments are tactile and positive. Magnification adjustment is firm and gives a quality feel. 3-9 power is probably overkill for my .177 but better to have and not need than need and not have. I generally leave the power at 5 and go about my business. Zeroing the scope wasn’t an issue once I got the mount tight. I put a slide stop on it and also put some Vibratite on the dovetail itself. Once secure it zeroed right away and has held zero without issue. As long as it holds up to the violent recoil of the nitro piston gun it is a winner for sure. I’ll update this review as time goes on. ... show more

    • Recommended for strong air guns
Good scope for magnum air guns and high power PCPs, too. Good light, sharp view, but average adjustment system. Set zero for specific range and do not touch.

    • Seems to be great value
So far giving it five stars. Like others mentioned the packaging is absolutely outstanding. Have it mounted to my Gamo swam whisper fusion mach one and have it sited in at 35 yards. It is holding zero no complaints so far. I will post an update if anything changes.

    • Needs frequent adjustments
Shipment packaging was good and external appearance of scope is high quality. It was almost impossible to zero when put on (new) on my HW50S break barrel .177 air rifle. I decided to center the reticles and it then would zero easily. The ocular lens loosens until you apply blue Loctite. The objective lens has an external threaded ring which also needs blue Loctite. I use my HW50S and the scope mostly for precision target shooting at 25 yards - my standard is less than 1 inch tight centered groups. Once you zero the scope it is good for 20 or so shots and then needs slight adjustments. And it is almost always out of zero for next day's shooting. To be fair, all my scopes (some very expensive) need adjustments of 2 to 4 clicks during range sessions. This scope just needs more frequent adjustments than my Hawkes and Nikons but is a good option if you don't mind making the adjustments as the glass is bright and clear and the cost is budget friendly. We will have to see if it is really a strong unit as claimed for spring piston air guns. So far so good with about 400 shots under it. ... show more

    • Fine scope for 60.oo dollars
I have this scope some 2 month ago, in february 2015 for my Gamo Big Cat .22 and fired about 500 pellets. Put in zero was very easy, begining at 10 feet and 4X, the AO option must be used to go in focus. After that I put the 8X magnification, the one I want, and moved the target to 10, 20, 30 and 40 yards, 10 shots each. Vision is very clear, even when sun go down about 600 PM. Controls has force enough to keep without movement, but easy to place where you need them. Mil dot option is fine to change POI at a different distance, so the AO. The only negative thing is the one piece rings, they looks strong but are the low profile and does not let use the lens cover, rings should be mediun size for the 40 MM objective. Seller must take this in consideration; several buyers complain about the same issue. Now in april 2019 I want to add an actualization after 4 years of use in 3 differents rifles, Gamo Big Cat, Hatsan 85 Sniper and now on a Gamo Wildcat Whisper: excellent service for hunting or target shooting, controls stay always in place. I am planning to get the 4-12XAO in the near future. ... show more

    • Fantastic Scope
This is my first experience with a Hammers scope, and I must say that I'm impressed. This scope was a replacement on a friends air rifle. After mounting and bore sighting the scope, I sighted the rifle in, which was extremely easy due to the accuracy of the scope controls. It tracked flawlessly through a grid test and the parallax adjustment proved to be accurate at all the distances that I tried it. This scope is a terrific value for the money and I feel comfortable recommending this scope. ... show more
