Bore Sight Kit for .17 to 12GA Calibers BoreSighter with Button Switch Red Laser Bore Sight | Pre-zeroed Bright Laser for Long-lasting Value, Case with Identifiable Adapters for all Common Calibers, Instant On/Off

This bore sighter works great. For the money , you won't be dissapointed.

Very affordable all-purpose in-barrel boresight. I found this model to be far less flimsy and more reliable than many other models I've tried (without buying any boresight kits that cost over $30). Pros: Very complete kit, comes with all tools you'd need (plus some) and adapters for nearly every caliber Easy to use, especially compared to some other kits I've seen Fairly accurate, gets me to within 1-2 MOA so I have less sighting-in to do at the range Overall good features like on-off switch so you don't have to keep adding and removing the batteries every time you use it Amazing ROI for a boresight kit, the value and practicality can't be beat Cons: Not going to get you extreme accuracy - but no boresight ever will Battery case is a little finagle, once you figure out the unintuitive way it goes in tho you're fine

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.

Works great to get your close

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 nice kit and easy to use and figure out

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

Have bought similar item before for my shop. Wore out due use. bought again due quality. Shipped fast.

solid bore sighter....great product. Did a great job at sighting in my rifle. With the bore sighter in your barrel, and the firearm firmly supported on a stand, bipod, etc, aim the laser at a target, then in small increments, rotate the laser by hand, you will see that it makes a small circle on the target. Find the center of that circle, then dial in your scope. Works perfect. Highly recommended item, and highly recommended procedure.

used it on some air rifles , helps with quick setup . not the best lazor , but 40- 50 feet it works well

works fine

very easy to get on paper

Terrible product
