Tool-Free Laser Bore Sight Kit : Green Laser Bore Sighter with 64 Upgraded Adapters fit 0.17 to 12 GA Calibers| Multi-Caliber Laser Bore Sighting Kit for All Gun| Powerful Boresighter

Worked as it should. Seems to be of good quality. Note that all the adapters pictured aren't for "all" different calibers. Their are actually two sets of the same adapters. One set that you use the included screw driver to install into the tool, and the other set have a small "knurled" Allen screw on the end with the idea being that you can swap them out with your fingers. I find that your fingers work just fine with either style of adapter. That being said, there still are many different sized adapters that will fit pretty much all smaller calibers. Overall, a very nice little kit!!

Nice kit bought it to sight in my red dot before going to the range. Very happy this got my red dot spot on. Amazing for the price

This works exactly as described and is great! I’ve recommended to a few friends so far. Comes with two batteries and a ton of bore sizes. Really useful and accurate.

My bottom line up front is that I think I will keep it and use it for the purpose it is intended for. That said the purpose is to align sight with center bore axis of weapon (for the first time). The intent is to be close enough so that when you put your point of aim on a target at whatever distance you prefer to zero at, the point of impact will at least be on the target somewhere (being on paper). As opposed to lost out there and totally miss the target area. I remember way back in the day it once took me about 9 rounds to put a hole on the target area. From there you adjust the sight whether it be a laser, red dot, scope or iron sights to the point of impact. My experience so far was to align a laser sight on my handgun as it was just replaced. Since this is a small pistol with a 1.9 inch barrel it is intended for conceal carry and self defense at point blank range. I attempted to align these lasers up at approx 50ft during a cloudy day. To my surprise I could not see the laser that far away on target. But no big deal as I couldn't see the pistol laser either. My thinking is to use this at night to align them. Also note the use of laser on this handgun is mostly for low light and night use anyhow as when you can't really see the front and rear sights well enough to align. I tested laser at night and I can easily see the beam around 300 ft away in the dark as well as the pistol laser. The mfgr claims to be able to align sights out to 200 yards or so? I don't know for sure on that (I didn't try this for rifle yet) but the target area would have to be very dark to see laser so take it for what it is worth. Either do this at night or somehow have an extremely dark target area to see laser during day even at 50 feet. The product seems well made and the bore adapters are of good quality, you basically get two of every size. and the beam calibration seems perfect as delivered. If you put the beam on a target and rotate laser 180 degree the beam should not change position or move as mine did not, it was rock solid. It simply is not a crazy powerful highly visible laser that you can see easily in daytime conditions without some target area prep. For the bargain price keep your expectations within reason and with that in mind I recommend the kit. If you use this like 10 times it should almost pay for itself by NOT wasting rounds and time. Hope this helps.

works good from my .177 BB gun to my 20 Gauge would recommend

This is seriously an excellent bore sight!! I was struggling to get a new Vortex red dot sighted in on my Sig X-Ten 10mm wasting more ammo and time than I care to admit. Bought this, easily made the adjustments needed at home. Went back to the range to test, and it was dead on! Couldn’t be more pleased!

As advertised. Easy to use but not ready to use right out of the box. You still need to center the laser before you bore sight the rifle. Plenty of information on this on YouTube. Once I accomplished that by adjusting the four set screws that support the laser, it was spot on and bore sighted dead center. I would definitely recommend this to anyone that has a need for this tool.

Tired of single-caliber bore sights? This is a perfect product for those who need or might need to work with multiple calibers. Instructions could be a little better, but the laser is bright, easy to use, and a huge time/cost saver!

Works great

Product is amazing in daylight and visible compared to other products. Highly recommended for bore sighting. And 5 stars also for the merchant

Great kit could use better numbering for the different sizes instead u got 2 card u gotta look at 1 for caliber and 1 for placement in the set could fix with just numbering the set instead of having to look at 2 different cards .btw if u don't need handgun sizes I would suggest not buy the bigger set it just more confusing I live in Canada but bought the big set for the extra few bucks now I regret it cuz there's lots of extra pieces that will never get used and makes selecting the right rifle size more challenging also laser is great at 30 to 50yrs haven't tried at 100yrs but was close to center at 100yrd after sighting it at the closer range
