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

This is a solid tool to have for your guns. It’s easy to use and works well. This will save you money almost right away by not having to fire off rounds to dial your sites in. You still should site your rifle at a 100 yards with this to dial it in. Great tool though and works well. Recommend.

Shipped fast, and product works as it should. Like having the multiple caliber attachments and the laser is crisp, making for an easy bore sight. Cannot comment on battery life yet as only used it about 7 minutes total, but it includes and extra battery so likely an added plus.

This is an inexpensive laser bore sight tool, but it gets the job done. Don't expect it to be as accurate as the more expensive models and you'll be pleased with it. There are a half dozen or so little adapters that come with it, and the instructions tell you what caliber range each one fits (they are all in US imperial measurements, so you'll need to convert that to millimeters on occasion). None of the adapters are labeled, not even with a little number to correspond to the instructions that shows each adapter with a number beside it, so don't lose the little directions that come with this. I just laid all of the adapters out from largest to smallest to help me find the one that fits the caliber range I'm trying to sight in. They work by threading the adapter in at the end of the bore sight by hand until the plastic on the adapter just seats on the plastic of the bore sight. You then insert the end of the bore sight into your barrel and check for play; if there is too much play, pull out the bore sight and tighten the small philips head screw a little at a time. This causes the plastic on the little adapter to compress into the bore sight and the adapter expands. You do that until you can insert the bore sight into the barrel and you remove as much play as possible without making it impossible to insert into the barrel. Don't try to force it into the barrel if it won't fit, you'll just break the little adapter, they are pretty fragile.Remember, this just gets you into the ballpark. Make sure you are trying to sight in at the distance you want to zero your irons or optic at. I recommend resting the f*rearm on something stable and stationary while doing this, it will help you avoid some frustration. Just to give you an idea of how much wiggle room there is for where the bore sight is telling you the POI is and where the round will actually go, try rotating the bore sight while it's in the barrel and you can watch the dot move on the target as you do so. This won't help you get your sights dialed in exactly, but it will get you pretty close and save you a lot of ammo compared to doing it the old fashioned way.

WOW! Fast and simple to use. Did my .380, 9mm, and 12 gauge. Would recommend this device to anyone and everyone.

simple and effective design. Very reasonable price.

The length is too short to work for my bolt action riffle with the muzzle break attached. It will likely work fine for rifles without a muzzle device installed.

Excellent for zeroing optics

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.
