CVLIFE 2.5-10X40e Rifle Scope Review
The CVLIFE rifle scope is certainly in a ball park of its own. It's a rifle scope that also has a gun sight laser mounted on it for positive target acquisition and accuracy. The crazy thing about this scope is it's not only under $100, it's under 50 bucks! To get the perks that this thing is offering, it's a steal in our books.
The rifle scope has 2.5-10X magnification with a 40mm objective lens. To enhance image quality, it has multi-coated optics with a Kellner eyepiece for correct dioptric adjustments. The external lens also has a scratch-resistant coating to protect it from dirt, debris, smudges, and scratches.
But, back to the laser feature, the 5mW red laser can reach out a full 100 yards. Used for close range shooting, you can also correct for both windage and elevation adjustments to ensure the laser is accurate with your rifle.
Additionally, the rifle scope also has both a green and red illuminated MIL-DOT reticle that's been perfectly designed for .223 caliber 55 grain bullets out to 500 yards. The illuminated reticles each have five levels of brightness and can be turned off to take advantage of the non-illuminated, black reticle.
If all these perks weren't enough, CVLIFE also throws in a 20mm and 11mm mounts to fit with your type of rail. Most buyers say they had no issues with the mounts or installation right out of the box. However, like with most cheap scopes, there are quality control issues that range from reticle issues to loose construction. Some issues can arise from incorrect installation, but it's important to do a proper once-over of your product during the warranty period.

CVLIFE 2.5-10X40e Scope Q&A:
Where is the Instruction Manual for the CVLIFE Rifle Scope?
CVLIFE imports their optics with strict regulations not to include paperwork. However, this is a major issue that they're working on addressing for future purchases. Since they don't include any written paperwork/instruction manuals in the box, you can download their instructions online or have them email you the manual.
Do I need to Register this Scope for Warranty?
You don't need to register your product with CVLIFE to insure warranty service. All their rifle scopes come with a one year warranty. You can email their company for support service if the need arises.
What Batteries do the Illumination and Laser Features Require?
The gun sight laser requires 2 x LR44 batteries and can be replaced by rotating the laser switch counterclockwise.
Both batteries are placed positive side up, and then the switch is placed back on and tightened back into place clockwise.
The illumination reticle batteries can be replaced with a single CR2032 battery by using a flathead screwdriver to open the illuminated reticle turret for replacement.
What is the Bullet Drop Compensator?
The turret on the top of the scope has five markings to indicate for yardages up to 500 yards. When sighting in your scope, use the "1" marking to zero for 100 yards. Each marking up to 5 will indicate an additional 100 yards to compensate for bullet drop.
Can the Mil-Dot Reticle be used at any Magnification?
No. This rifle scope has the second focal plane reticle where the bullet drop compensator reticle is only effective at 10X magnification. For more clarification on reticles, see our "Reticle Subtension Explained" article.
Does the CVLIFE rifle scope have an Auto Shut-Off Function?
Both the illuminated reticle and laser sight do not feature an auto shut-off function. They both have switches to manually turn them off.
Does this Scope have Parallax Adjustment?
No. Since the scope has magnification 10X and under, it's really not necessary to sport that feature anyway. While the specific factory-set parallax yardage is unknown, we assume it to be about 100-150 yards.
How to Fix Loose Screws from Recoil?
Some issues buyers are experiencing are loose screws either from recoil or poorly-made scopes. A little bit of Loctite threadlocker adhesive seems to the trick for many users.
- Illuminated reticles for poor light conditions
- 5mW red laser sight for close range or rapidly changing environments
- Windage and elevation adjustments for laser
- .223 BDC turret for 500 yards
- SFP Mil-dot tactical reticle
Our Verdict on the CVLIFE Scope
According to the bull's-eye, the CVLIFE 2.5-10X40e rifle scope is an instant buy with immediate perks. To be honest, the scope is a little heavy for a 2.5-10X40 scope, but with the additional laser and illuminated reticle options, that extra weight is warranted. We even think it is one of the best scopes for an AR-15 in the under $100 price bracket.
To keep things in perspective when shopping for a rifle scope under 100 bucks, the UTG BugBuster 3-9X32 rifle scope is a worthy competitor for the CVLIFE scope. It sports both the mil-dot reticle and red and green illuminated options. While it doesn't have the laser sight, it does sport an AO feature. Not bad right?
However, sometimes keeping the extra perks down and increasing optical quality means more in the hunting and shooting field. The Barska 3-12X50 IR Huntmaster Pro Rifle Scope keeps it simple, but it still throws in its hand with the illuminated reticle.
In the end, the CVLIFE rifle scope has a lot to offer. If you can get your hands on a fully functional one, it's a keeper for sure, especially with the ridiculously low price tag. With a laser sight, BDC turret, and illuminated options, there's no way you won't be able to fill your tag!
