EZshootBore Sight Kit for .17 to 12GA Calibers BoreSighter with Button Switch Red Laser Bore Sight

Great product for what it is and the price. Don’t expect is to be super fancy even though it seems moderately well built. It’s not designed to fully zero. Just get you close enough to save you a little more time at the range. Mine didn’t have any laser or function defects and appear to work well.

Very satisfied with purchase.

Works good so far. Have only been able to test it at 25yds. Stable and centered inside the barrel.

Great value, covers multiple calibers, easy to set up and use. No issues, arrived as expected and was well packaged to prevent damage in shipment. I don't know how long the batteries will last but the unit came with two complete sets, a nice plus!

I have used multiple laser bore sighters throughout my life and this is by far the worst one I have ever tried to use. The cartridge based bore sighters I have used were better than this in every way, and that's saying something.I put on the proper adapter according to the specs in the instructions and it literally wouldn't even go into the bore of my rifle. I follow the instructions to a T the first time. The proper adapter torqued to the proper "spec" (manual just says tighten the adapter until it flares out, which I did). It did not fit into the bore of my rifle. Not even close. So from there I adjusted it. I couldn't get it into the bore of my rifle even with backing off the adapter screw, which lessened the flare of the adapter.The device I have doesn't even match the instructions. The pieces they show in the manual are not what I received and therefore do not work as described. It was a struggle to even get the batteries in correctly and make this thing work at all, based on the instructions. The instructions were completely wrong in that in nearly every regard and I had to resort to just doing what I thought was best. Then I was able to make it work, sort of; because while I got the laser to function, I could not get the device to fit inside of the bore of my rifle ever. When I did get it to work (aka got the laser to turn on, because again, NO WAY is this fitting into a .223/5.56 bore), the laser I saw was this huge and terrible blob (no, it is not my eyesight). There's no way this would be able to ACCURATELY sight in a rifle for a 50/200 zero, even if you were using a 10yd target. The laser for POI is just too huge and grossly inaccurate at best. At worst it's a total liability.I couldn't be less satisfied with this. It was absolutely terrible in everyway. Even if you go it to work, and were willing TO SHOVE this Chinesium down your muzzle; the accuracy would be suspect at best due to the blob of a laser it puts out.YMMV but this is absolute trash. Returning ASAP

This is a decent laser bore sighter it's not the worst but certainly not the best, in my opinion you get what you pay for sometimes. I can only give it 3 stars and I'll explain why.It took some adjusting because lucky me they sent me one that the laser was off Center so I had to set up a jig that would hold my gun steady cause I dont wanna buy a rifle stand, while setting up a target or really just a bullseye 🎯 once I found a good reference point I was able to rotate this sighter and it was way off it was so bad that when I rotated it a quarter turn the laser came off the paper. I wasn't real pleased with that but there's good news and that's what makes this product worth the investment because it is fixable all you have to do is adjust the Allen screws on the end of the laser and it will bring it right back around although it is a tedious process and takes some ingenuity and a lot of time it's worth doing because the alternative is trashing it.I almost threw this thing away but I didn't however I will say for a multi caliber sighter this one is decent but I certainly wouldn't use it as my primary because it goes on the end of the gun and it's easy to bump and get off target I'd much prefer a chamber type boresighter but with small caliber like .22LR you just can't find it so this is the best alternative that I've found.Sure beats putting countless rounds down range just to get sighted properly.Lastly one thing that really was bugging me was the battery compartment, (I must say this I don't read instructions on simple products) I was doing it all wrong the battery compartment was so frustrating to work with that alone almost made me trash this thing but then I decided to read the instructions and I found out there is this little cup that the batteries sit in and needless to say from now on I'm gonna read the instructions from the start. When I decided to use that cup I had no issues installing 4 batteries do keep in mind you need to install 4. Three of the batteries fit into the cup and one stays outside and I found it was easier to install the battery that was outside the cup in the back opposite the spring and it made it look weird but I didn't care about that I just wanted it to work so that's what I did.Would I recommend it? Yeah I mean for the price it's worth it even with its quirks, hopefully yours will actually be on sight and centered properly and lastly don't be like me and disregard the instructions they're actually useful.

Very accurate

Works good and help me
