Simply adjust your sights or scope, and save your extra ammo for the hunt. P2M Boresights offer the highest quality boresight on the market.
Sight
Accuracy has never before been so easily attained than with the P2M series of in-chamber boresights. The P2M boresights deliver precision accuracy without wasting time and ammo at the range. Once placed in the chamber of a firearm, the red laser dot appears exactly where the barrel is pointed, allowing the sights to be adjusted to the theoretical impact point.

I have used a couple of these laser bore sight tools and this one works just like the others. First off, you need to chamber it manually. Lock the bolt back and place it in the chamber by hand. Slowly release the bolt to touch it. It is a laser and you cannot expect to put it in a magazine and load it that way. That will destroy any brand of laser bore sight tools. There is no switch to turn it on or off. Having batteries in it causes it to be on.Remove it with caution as well. These are as delicate as a laser pointer would be. (don't eject it like you would a regular round) This could mean locking the bolt back and shaking it out manually.I find that these are excellent for setting windage. They get you right on target. The elevation is a different story. I suppose at a specific yardage it would be perfect but I have found that it just "gets you on the paper" and you can manually adjust the elevation by trial and error after you remove the tool. I really do like to be able to quickly get the windage perfect though.These are relatively cheap and if you know how to chamber it without damaging it they are easy enough to use. I used it to setup a red/green dot optic. I changed the optic to green and that helped me to get it setup. (red would have been confusing)I put mine in a ziplock bag and kept the packaging that the batteries came in. I threw in a roll of electrical tape and I put tape on the battery packaging to keep them in place. I don't want the batteries to somehow discharge when I'm not using them. The entire ziplock is in my range bag if I need it.To be honest, I really wouldn't need this tool to setup my red dot. It does make it a little easier though and I know for sure that the windage is dead on when I am done. I was borrowing one of these from a friend and for the price this is so much easier than borrowing one each time I need it. They say if you borrow something more than twice you should just buy you own. I did that I bought this tool.

This boresighter worked for one if my rifles without issue(s). The boresighter is easy to use. I borsighted in at approximately 30 yards and it put me close on the target at the range. Any time I can save ammo is a plus. The batteries lasted me for the 10 minutes of use I needed. I took the batteries out after usage and the boresighter still works for the next time I need it.

No batteries. It clearly says they are included and they are even in the second picture. Don’t get me wrong, the thing seems like it’s built well, but how am I supposed to know that? There is no power source. I need this gun sighted in for tomorrow which is why I pay for prime, on time, fast shipping. And I bought this because it looked well made and supposedly included batteries and would be here by today. I live in the country and now have to go look for some obscure lithium ion batteries at the feed or hardware store in town. I don’t have a good feeling about that... if the product works well and the seller does something to make this right, I may very well change this review to five stars. Until then, there you go.Edit: I finally got to a neighboring town and got some 357 batteries. While I’m still not happy that it didn’t come with batteries as advertised, once I got them this is the best made laser bore sighter I’ve ever owned. Including the expensive ones for rifles and pistols. All of them could use an on/off switch, but on the last thread, this one turns off. My others don’t. Dot is crisp and clear and it’s quite well made. It seems very sturdy and I expect it to last a long time. Please guys, work on your QC issues and you could have a real winner here. The seller did finally offer to send me batteries if I sent an email to their customer support (annoying. Should have just sent them to me without me having to do anything, seeing as how they have my address and all). Overall, I hope this company starts doing a better job with quality control, but with that said I would highly recommend for less than $9.

It works perfectly and as intended. I really enjoy the simplicity of it. But I would like to try and help others out in case they're worried about the negative reviews left for this.1- Yes, the batteries are going to go flat pretty quick. This is common for any sort of light emitting object left on for any extended amount of time, but especially for this kind of laser. The batteries that go into this thing are TINY, and they also are not the kind I was able to find at my local store's endcap. So, do be ready for that. Since you're buying it off of Amazon, go ahead and look for 393/309/193/AG5/SG5/LR754/SR754/LR48/L750/1136SO/1137SO batteries. I suggest looking for them by any of the first 4 numbers given, but any should work as long as you make sure they are, in fact, the same battery. You'll see when you get them that the batteries are incredibly small and don't hold much juice. If you plan on spending any amount of time really sighting things in, extra batteries would be a great idea.2- This does not have an on/off switch because that would provide extra bulk. It is intended to be used right away, so try and make sure to have everything set up before you pop the batteries in. This will make everything a lot smoother.3- DO be careful with how hard it is chambered in. It won't be ejected like a typical round because of its design, so try and possibly have something to help gently tap it out of the barrel on hand should it get stuck.
