Elite Force Optics Absolute Zero Easy One-Shot Laser Rifle Zeroing Device for Rifle Scopes, Absolute Zero Device (8 x 3 x 4.5 inches)

This device is fabulous, it works exactly as described and made zeroing my rifle a breeze. No matter if you intend to mount it on an AR, 1" scope tube or 30mm tube there is an accessory for every option. The twin lasers are very bright and get you right on target fast, saving ammo and money. For the price an incredible value, very well made, and will definitely pay for itself fast!

This pays for itself in the cost of ammo you would waste. I tried bore lasers but this is a lot more effective. Its more complicated to install than a bore laser, but relatively easy. What I like is that it stays on the weapon while you shoot compared to a bore laser which requires you to remove when you shoot.

lots of videos online regarding setup and its pretty straight forward - ive only used it on two guns, my new cross and a lever gun with a red dot. It works pretty well under moderate lighting conditions and can be difficult to spot under very harsh and cloudless days.

Nothing to dislike about the item. It also can eliminate the "need" of having to keep your rifle locked down in a vice/sled. As long as you can put the two dots exactly where they were during the first shot, you can make your scope adjustments to be fairly close, not precisely close but close. It's a great tool to add to the list of making life easy while sighting in.

The product does not function as advertised. The barrel clamp is designed for shotguns, not rifle barrels. To mount it, had to wrap the barrel with paper. Additionally, the laser is extremely weak; it's not visible on the target 25 yards away during daylight. The laser only becomes visible at night, making it impossible to sight in the gun properly. The videos on YouTube are misleading. Overall, very disappointing.

Perfect for practice!!!! Very accurate!!!

I tried to use this as instucted but a few things limited it's usefulness. 1) Unable to use at all in the direct Pheonix sun light. 2) There are no adjustments on the device itself. On a very crowded range, there may not be angle enough to align the paper, barrel and lasers at the same safe space. On the AR rail this was not an issue but was an issue on the bolt action rifle scope mount. 3) The springs that are used for the batterys were bent in a way that when installing the batterys shorted the spring to the device. I think a version 2 of this device with green lasers, adjustements and the battery springs addressed would make this a no brainer device.

This thing is the bomb. It literally took 10 min to set up and at 25 yards my 177 pellet gun literally shoots through the same hole.

I am a very happy camper with this item.A little wary at first but any concerns evaporated with my first sighting. I attached the unit to the scope mounted on my brand new 6.5 Creedmoor as directed; Placed a target 25 yards away, stuck he special calibration sheet provided onto a normal target and following simple directions .... one shot and I was zeroed. In a nut shell, its simple, well made and it works. I would only add that you do this on an overcast day when the lasers are easier to see on the calibration sheet..
