EZshoot Bore 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.

Well worth the price paid.New gun owner with a red dot installed already. Using the gunsights to zero was difficult. Boresight made the task quicker. I have my optic red dot just slightly below, with an overlap, on the boresight red dot. Works awesome.

Pros: Pretty close to universal, especially if you're willing to tinker with things a bit - there's different size plastic plug things that screw in the back to work with different calibers, and if you don't mind making something that fits right (maybe from a bore brush?) or using a little plumber's tape or something to get a good fit, you can probably make it work with anything less than a .50. Dot is nice and bright, whole thing feels pretty solid and well made, comes in a nice box with batteries that worked and all the tools you need (allen wrench, screwdriver) and a little sight adjustment target table thing.Make sure you screw the back end thing in enough to push it up onto the post, which spreads out the plastic. Otherwise you'll have a bit of a wobble in most firearms. Tried it with a .22, .223/5.56, two different 9mms, and a .30-06. Pictures above show it in a Springfield Hellcat and a S&W M&P Shield 2.0... the latter with the factory Crimson Trace laser also on. As you can see, the two dots are pretty darn close to each other, which is good. You do need to jam the thing in there as best you can, though, or maybe wrap the end in something to get a tighter fit on some guns. A dedicated single-caliber bore sight won't have that wobble... but then if you're like me you'd need a half dozen different bore sights.So long as you remember that these things are not for precision adjustments, just for getting it on the paper before you fine tune your scope, you're good. My guns spend far too much time just sitting in the safe, so it's an easy way to do a quick check and see if anything's been knocked out of line before I go shooting.

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

Accurate, easy to use, can be a pain to figure out but once you get it it's fine.

Works good and help me

This is awesome!
