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

This works good. It help sighted my canted short range scope to a proper zero of 30 yards for a 22lr. The light doesn't really work that well in the outdoors unless the sun is covered by clouds. But the test fire did land the shots on targets.

Easy to use fits more calibers than I own.

This is a great well made sight-in device. Fit snuggly and properly in every barrel. The green laser is really bright. The case makes storage and selection great. With 64 calibers included I can't think of any shortcomings. Money well spent.

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.

This kit is awesome. Very accurate. Only had to make a very slight minimal adjustment to the laser to get it true. The price is great. This bore site will bore sight anything from 17 cal to 12gauge. I have used this kit to bore sight new guns and ones that I have already had sighted. Some that were already sighted were off just a touch. I would recommend this kit to any one.

This bore sight has every caliber you could ever want. It has worked great for me.

This is the best investment for shooters bar none. This kit has everything you need. A quality product and packaging is awesome. The laser is super bright and functionality is easygoing. The perfect tool to get zeroed without wasting ammo.

Nice kit I recommend
