It offers 4 customizable reticle options and 8 brightness settings, easily adjustable via push-buttons. Designed for 20mm Picatinny rails, it installs quickly with included tools and maintains zero under heavy recoil, making it a reliable choice for precision shooting in varied lighting conditions. ## Description Product description CVLIFE 40mm 4 Adjustable Reticles Red Dot Sight Specifications Co-witness with Iron Sights The center hight of CVLIFE reflex sight is about 1.45 inch, high enough to see over a standard front iron sight. This red dot reflex sight can co-witness with your front sights. Tubeless design with 40mm reflex lens aperture provides quick sighting. Press Button Each press to turn on reflex sight. Each press to change 8 settings of brightness. Hold the press for 3 seconds to turn it off. Windage /Elevation Adjustment Rotate to adjust the point of impact, zero the reflex sight. (tool included) Each click adjustment moves the point impact by 1 MOA. Picatinny Shockproof Base Equipped with a 0.15-inch metal locking bar, this sight maintains zero even under heavy shock, compatible with 20mm Picatinny rail. Anti-fog Coatings This reflex sight can quickly become clear when fogging with rapid changes in humidity or temperature. Review: Light weight, easy to install and adjust. - I like it! It was very easy to sight-in and came with the necessary tools to attach it and make adjustments. The reticle is powered on/off by a small pad on the left side. Press repeatedly to cycle through several brightness options and a switch located at the back selects any of 4 different reticle images. I believe the lens has an anti-glare coating to allow the user to see clearly in many lighting conditions however, from the front side it is highly reflective which may be counterproductive under certain circumstances. It seems to be of good quality and could be used with an iron forward sight for greater confidence and easier tuning but I like it without. I was able to center it within 5 rounds to a target 30 yards out. I’ve put nearly two hour of use to it and have not had to change batteries yet. It has an auto shut off feature as well. This has performed just as well as my other “Big Name Brand” sight at a fraction of the cost and with more functions. 2026/4/24 Update: It has been several months now since I first purchased the CVLife Reflex Sight. The batteries are still working effectively. My “big name” sight power drains the batteries (unless I remove them) within a week of storage. I’ve range tested this sight with 1500 rounds of 9mm on my S&W Carbine before giving it a try on my M&P15 NATO. It handles the recoil very well and I’ve spent 1000 more rounds. After the first 500 using the new caliber, the mark did shift slightly left. A minuscule tweak with the supplied hex key and it was spot on again at 100 yards. I’ll be keeping an eye on the shifting, but when I can sight in and ring out a bullseye at 100 yards with a single magazine, I cannot complain at this price point. I’ll try to come back with another update after a couple more range visits. I generally spend 250 to 500 each trip depending on the time I have. I have other arms I practice with and I’m not sure if this sight can handle being mounted to my M&P10 NATO, but for the price I might try it and just buy another if it fails the intense recoil hammering. I see a newer model that features an internal USB rechargeable battery but my experiences with those have not been great. Keep in mind, it’s good maintenance practice to retighten all your fittings after so many uses, which may also require realignment. I go by round count for both cleaning and tightening, but I will re-clean when unused for longer than 3 months. You should also readjust your sight whenever you remove/replace it. Review: Value Priced & Functional ⭐️UPDATE⭐️ - 🆕 UPDATE: the firearm and sight have been stored for a few months and just completed a functionality test - THE SIGHT ILLUMINATED PERFECTLY AFTER STORAGE! Heading to the range! ORIGINAL POST: Just mounted this CVLIFE REFLEX SIGHT Optic on my Henry .22 Pump Action Octagonal Barrel Model H003 Rifle using the LONSEL Dovetail to Picatinny Rail Adapter 11mm Dovetail to 21mm Picatinny Rail Convert Mount - Low Profile Scope Riser Rail Adaptor and love it. Wanted an inexpensive alternative to iron sites. My indoor range allows for .22 Rifle @ Approximately 20 yards so my dial in information might not please all readers. Fired .22LR Velocitors and .22 Shorts. The range is a bit dark and my iron sights were not easy to use so I took a chance with this setup. Installation is simple, connection to rifle is secure, adjustments are easy to make, the sight is bright enough and has a variety of sites and illuminations to select, remained true after 100+ rounds. DOES NOT ‘Shake Awake!’ Similar accuracy to my ability with iron sights but with faster target acquisition. Arrived in secure packaging, two sets of batteries, lens cloth and adjusting tools. I have experience with the Romeo X Red Dot Optic on .380 handgun and while this less expensive alternative might not be appropriate for that application I think it’s perfect for this .22 Henry Rifle. Photos of firearms are generally prohibited so subjectively I think the setup looks aesthetically appropriate on my rifle. Might visit our local outdoor range and try 50 and 100 yards. Very good recommendation for this product. Hope that this review is helpful/useful.☮️ ## Features - More Accuracy: Fully multi-coated red lenses improve image clarity and increases light transmission during low light situations. The 40mm reflex lens with tubeless design provides a wider field of view (15.8m at 100m), parallax corrected & unlimited eye-relief, improving the accuracy of reflex sights. - 4 Reticle Options: Illuminated reflex sights with 4 bright reticle selections provide various choices to meet different occasions. Dot, Circle/Dot, Crosshair/Dot and Crosshair/Circle/Dot combinations are all in one sight, co-witnesses with your existing iron sights. - 8 Brightness Settings: With 8 levels of brightness adjustment, red dot sight can be adjusted to fine tune your eyeshot from sunlight to dusk. The push-button design makes brightness adjustment easier. Press the button for 3 seconds to turn it off. - Easy to install: Reticle sight with standard profile Picatinny mounting base installs conveniently on the rail, using included Allen wrenches. Compact battery compartment makes battery replacement easy. - Resilience: This open reflex sight with precise windage and elevation adjustments is easy to zero and holds zero well, enduring repeated use. CVLIFE red dot sight has a solid build, aluminum sturdy construction and a tinted lens, robust and shockproof (withstand up to 800G’s recoil). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09H5XK8RT | | Best Sellers Rank | #13,298 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #7 in Airsoft Gun Sights | | Brand | CVLIFE | | Brand Name | CVLIFE | | Color | Black | | Compatible Devices | Picatinny Mount | | Customer Reviews | 4.3 out of 5 stars 1,247 Reviews | | Eye Relief | 44 Millimeters | | Field Of View | 15.8 Meters | | Item Weight | 5.3 ounces | | Lens Color | Red | | Magnification Minimum | 1 x | | Manufacturer | CVLIFE | | Material | Aluminum | | Material Type | Aluminum | | Model Name | FoxSpook | | Mounting Type | Picatinny Mount | | Night vision | No | | Objective Lens Diameter | 44 Millimeters | | Product Style | Red Dot Sight | | Reticle Type | Dot | | Sport | Hunting | | Sport Type | Hunting | | Style | Red Dot Sight | | Unit Count | 1.0 Count | ## Product Details - **Brand:** CVLIFE - **Color:** Black - **Compatible Devices:** Picatinny Mount - **Item Weight:** 5.3 ounces - **Magnification Minimum:** 1 x - **Material:** Aluminum - **Mounting Type:** Picatinny Mount - **Objective Lens Diameter:** 44 Millimeters - **Sport:** Hunting - **Style:** Red Dot Sight ## Images ![Reflex Sight, 1x28x40mm Red Dot Sight, 4 Adjustable Reticles Sight for 20mm Picatinny Rail, Red Dot Optics, Absolute Co-Witness - Image 1](https://m.media-amazon.com/images/I/71ma5LxmjtL.jpg) ![Reflex Sight, 1x28x40mm Red Dot Sight, 4 Adjustable Reticles Sight for 20mm Picatinny Rail, Red Dot Optics, Absolute Co-Witness - Image 2](https://m.media-amazon.com/images/I/71IZcxTmx0L.jpg) ![Reflex Sight, 1x28x40mm Red Dot Sight, 4 Adjustable Reticles Sight for 20mm Picatinny Rail, Red Dot Optics, Absolute Co-Witness - Image 3](https://m.media-amazon.com/images/I/71SaWuvaVuL.jpg) ![Reflex Sight, 1x28x40mm Red Dot Sight, 4 Adjustable Reticles Sight for 20mm Picatinny Rail, Red Dot Optics, Absolute Co-Witness - Image 4](https://m.media-amazon.com/images/I/71bufnVtXNL.jpg) ![Reflex Sight, 1x28x40mm Red Dot Sight, 4 Adjustable Reticles Sight for 20mm Picatinny Rail, Red Dot Optics, Absolute Co-Witness - Image 5](https://m.media-amazon.com/images/I/71f32ANkNlL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Will this fit a game .22 cal pellet rifle?** A: i think so. it fits on a 9mm pistol. **Q: Will this fit an xd-9 sub compact?** A: If it has a picatinny rail, yes.

I doubt your Taurus has that, probably more for rifles. If you do then it will fit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Light weight, easy to install and adjust. *by J***E on February 23, 2026* I like it!
