  • Recommended. Really great for the price range with nice features. Accuracy stays put.
Style: 11mm Dovetail
Pretty great scope. I haven’t had any issues with the scope and it is easy to adjust the crosshairs in the field. It stays steady on the rifle as long as you tighten the brackets and don’t bump it really hard. I dialed it in and it has stayed adjusted as set; i pretty much keep the magnification set to 9 so that is what I hd it set to when I dialed in the accuracy. Not sure what to do with the see-through caps as it has a yellow one i can put over the end to enhance the view but i find the view without yellow to be clear and easy to use. The only neutral point is how firm the adjustment ring is for distance; it takes work to adjust it and isn’t easy to twist. ... show more

  • Almost Perfect!
Style: 20mm Picatinny
WARNING: Kind of long review skip to the end if you are looking for the short review. If I could give this a 4.5 I would But you can't so gave it a 5 because 4 just isn't fair. Let me start out by saying you might not be able to beat this for the money. I say might because I have ordered the CVLIFE 3-9x40 Compact Rifle Scope Crosshair Reticle and with this only being 5 dollars more than the 3-9x40AO it might be better. Stay tuned for an update in about a week. I am one of those odd individuals that gets a kick out of trying to find the cheapest things that end up being gold. I will also say all returns are through Amazon and lets be real, having UPS come pick up the order for your return, or even having to drive 10ish min down the road to drop it off is not really a hassle. Now I will say waiting for it to get back to Amazon and then x number of days for your bank is a bit annoying. So trying out a 40 dollar item that I can return is a no brainer. Now for the pro's and con's. PRO: Super cheap! Fast Shipping! Took all of 6 rounds to sight in at 25 yards.... it was dead on on the horizontal axis, and about an 2 inches off on the vertical. Took me 6 shots because I wanted to test to see if the 1 "click" or turn was about 1 in at 25. And it was close. Also keep in mind you will be about 1.5 - 3 inches high depending on what caliber you are shooting at 100 yards . For the few reviews that say that they made an adjustment and it didn't move and then made another and it "jumped" twice the adjustment.... This also happens on a 1000+ dollar Trijicon. That's why in the military they tell you to smack it a few times before shooting your next group. (Disclaimer this is a 40 dollar sight I personally wouldn't recommend smacking it lol). Anyways when pushed out to 100 yards took 12 rounds to start putting holes in holes. The mounts it comes with are actually great. They tighten down with ease and the mounts have rubber pads to absorb shock and protect the scope. I have seen/used high dollar brand name rings that didn't have this. They say 3.9 inch eye relief and that is about right... I tried it anywhere from about 2.5 - 4.5 in and didn't notice a difference. CONS: At Maxed out magnification it does get slightly and I do mean slightly blurry. As great as the mounts are the screws are cheap so be carful when tightening them down. Also the provided Allen key doesn't seem to fit right. So just use your own and tighten it down hand tight. If you are the hulk maybe half hand tight. Also the mounts are high so if you want a low profile or a small person you will want shorter mounts to get that good cheek weld. Used on a 5.56 AR-15. Held zero on a 400 round day shooting without any kind of brace. And was accidently dropped like a foot. Which brings me to my last pro. For 40 dollars it held up to any kind of drop! PRO & CON: For the money I don't really fell like this is a huge Con but the Parallax is about 50-75 yards off at 100 yards. I had it set at roughly 150-175 the last number marking is 200 and than infinity. Conclusion: If you are on a tight budget 100% buy it. And yes I would recommend this scope. ... show more

  • Nice scope
Style: 11mm Dovetail
Good scope for the money, It was easy to mount on my .22 rifle and was easy to zero it in. Squirrels kept stealing all my pecans, this works great at 50 to 75 yards.

  • Huge Upgrade for My Crosman F4 – Finally Shooting Dime Groups!
Style: 11mm Dovetail
I’ve had my Crosman F4 for a while, and while the rifle itself is solid, the stock scope was a nightmare. I could never get the windage dialed in — no matter how much I adjusted, I was always off. I spent way too much time and pellets trying to make that factory glass work, and it just wasn’t happening. After some research, I decided to give this CVLIFE 3–9×40 AO a try, and I couldn’t be happier. The difference was night and day. The adjustable objective lets me fine-tune parallax for my exact shooting distance, and the zoom is a game-changer — especially for older eyes like mine. The image is sharp, the crosshairs are crisp, and the turrets actually track where they should. From the moment I mounted it, I was able to zero it in within five or six minutes. A quick couple of adjustments at 20 yards, and I was stacking pellets exactly where I wanted them. I pushed it out to over 60 yards, and I’m now hitting dime-size targets consistently. That’s something I never thought possible with this rifle before. If you’ve been fighting with the stock scope on an air rifle like the Crosman F4, this is the upgrade you need. It’s affordable, clear, easy to adjust, and makes precision shooting actually fun again. Highly recommended! ... show more

  • Perfect for backyard plinking/pest control
Style: 20mm Picatinny
Got it for my Umarex Notos. It’s sharp, bright, easy to dial in and the price is right. Highly recommend for backyard plinking/pest control. (Amazon won’t let me upload a photo because its attached to a thing that apparently goes against their guidelines)

  • Will Not Fit a Gamo Swarm Gen 3i Rifle
Style: 20mm Picatinny
I don’t want to bash this scope because I never got a chance to use it. I just want to warn owners of a Gamo Swarm Gen 3i not to buy it because there are no mounting options that will position the scope behind the Gen 3i loading system. It absolutely will not fit with any scope mount option. Don’t listen to “Rufus”! This Amazon AI tool will tell you that it will fit!!! ... show more
