EZshoot Bore Sight Kit Bright Green or Red Dot BoreSighter with Big Button Switch for .17 to 12GA Caliber

This is way way cheaper than the professional offerings and about the same price as chamber lasers but it works on all of the calibers that's a pretty big plus. The chamber lasers tend to wander if you reinsert them, with this I did try rotating the laser to see if it would wander and it did not it appeared to stay put regardless of its orientation when installed so accuracy at the range i used it at seemed great. This isn't going to turn your rifle into a tac driver on its own but its going to get you alot closer at the range to really dial it in with a lot less ammo I got green to contrast to my red dots sights.

Works like it states

I purchased this bore sight laser kit to zero my red dot sights without wasting ammo. After testing it on several firearms, I found it to be a convenient tool—especially for quick adjustments—though its length may be awkward for some handguns.Pros:- Wide Compatibility: Includes adapters for most modern calibers (9mm, .223, .308, etc.), making it versatile for different firearms.- Easy to Use: Simply insert the laser into the barrel, and it’s ready to go—no complicated setup.- Includes Extra Battery: Comes with two batteries, which is great since you won’t be left without power mid-adjustment.Cons:- Lengthy Design: The laser protrudes noticeably from shorter barrels (like pistols), which can be a little awkward.- Not a Replacement for Live Fire: Still requires final fine-tuning at the range, as expected with any bore sight.Key Features:The laser itself is bright and clearly visible in daylight, which helps with initial alignment. The multiple adapters ensure a snug fit in different barrel sizes, preventing wobble that could throw off calibration.I used this primary for pistols. The extended length made it a little unwieldy, but it still did the job. The laser held zero well when switching between guns.Compared to cheaper laser bore sights, this one feels more durable and has better-calibrated adapters. Some budget models have weak lasers or loose fittings, but this one stays secure.Tips:- Use it in low light for the clearest laser visibility.- Always confirm zero with live fire afterward—this is just a starting point.If you need a fast, no-hassle way to get your optics roughly aligned before range time, this bore sight laser is a great tool. It’s especially useful for rifle owners, though pistol users may find the length a minor inconvenience. It has saved me a ton of time manually trying to zero my sights. A solid buy for the price.

I've used the 9mm insert into the chamber and that didn't give me good results, but this mechanism was about right on the paper where I needed it to be. After a minor adjustments to my sight I was exactly where I needed to be. I also like the fact that I can use this with multiple chambers. One of my best accessory purchases.

Where do I start. I bought this to sight in my scope on my air rifle as well as some of my other weapons. It came fast and when I opened it up it was definitely steely poor quality. The idea behind this is decent, but it’s very poorly executed. The disc part you put on the end of the laser bore tool, as you tighten it, the disc should become tighter inside the barrel which it does.The problem is when I put this in one rifle I thought wow my scope was pretty close so I adjusted it and tested to make sure. It was way off. I put this in my ar15 and checked my scope and it showed it was way off however the rifle was very accurate. So I got to thinking and I rotated the laser bore tool and guess what!? The laser rotates in a small circle. ⭕️ it does not stay centered it rotates along the O of the circle so one way would say your spot on rotate it to the left now you are low and left. Rotate more you are way low and center. Keep rotating you are low and right. The laser is not centered into the bore tool. This is nothing more than China express junk. It is going back.

Works decent , it’s in mm not really in calibers , doesn’t fit overly snug in the barrel of the firearm , light flickered a few times.
