Visiofire 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

I’m really impressed with this laser bore sight kit. It’s simple to set up, the adapters fit everything I own, and the green laser is bright and easy to pick up even in daylight. What I like most is how much time and ammo it saves — I can get on paper fast and make clean adjustments before ever heading to the range. The build quality feels solid, the upgraded adapters hold tight, and the whole kit just works the way it should. For the price, it’s honestly one of the most useful tools I’ve added to my gear in a long time. I’m very happy with it and definitely recommend it to anyone who wants quick, accurate bore sighting without any hassle.

I just installed a new green dot sight on my Glock 22 and checked all my other red and green dots on 7 of my AR-15’s an the Glock went great with my new Visiofire bow sight kit and I am very pleased with it and such a great price and the assortment of calibers that you can do is awesome.

I have set zero on 3 rifles and 2 pistols so far. You pick the tightest "adapter" that will go into the bore then turn clockwise to tighten it deep in the bore with the conical part of the body snugged up to the barrel and viola, you set your red dot or scope to the laser. It reaches out a long way even in bright daylight. Easiest way to sight an optic. Love it.

I really like the brightness, or the viability of the green lazer dot at extended distances( daytime use) !! The Ease of use and accuracy as well! Mark T.

So my experience is that this works as a "bore sighter". In other words it will get you on the paper. On the plus side it comes with lots of barrel inserts to fit almost any caliber and has a laser powerful enough I can see it in daylight 50 yds away on the side of a barn. Downside is depending on how you turn the laser while seating it your point of impact display could be high right, low left, or anywhere in-between. Again it is just supposed to get you on the paper and does that well. Also on handguns the problem is magnified as the insert may not seat deep enough for the laser to touch the end of the barrel. Instructions are VERY limited but still found it easy to use. With some trial and error I was able to get the dot to hit the same location as my cartridge based laser insert for my 45. Had I not had the cartridge insert, I would have been very high left or very low right. I find it much better for rifles and can usually get within 2 inches of being on target with it.

Very useful tool. Saves money setting up new scope on rifle. Need to use a software program like "SiteLite" (free) to print out a calibrated target to make initial scope adjustments, and you will be "on paper" at the range with the first shot. Can't speak to durability yet, but if you take the battery out every time you use it, handle it gently, and always put it back in its (very nice) case, there should be absolutely no reason it won't last many years.

I tested it when I received it and this is a great product if you have multiple firearms. I'll be doing some range sighting this weekend with it.

For the price, you really can't go wrong. Aside from that, you really can't go wrong at all. I keep some of the dummy rounds with lasers as a backup or double check but they don't seem to be quite as accurate. Plus, for the cost of two of those, I can get this with adapters for 64 different calibers and the laser is about twice as good. Most of the little dummy rounds have a dot that is visible to about 20-25 yards in daylight but the Visiofire is good up to about 40 yards depending on the background surface you are using. My tip to purchasing the right color is to get the color of dot that is opposite of what you use in your sights. I prefer Green Dot sights so I went with a red dot bore sighter. If you get the same color, they kind of blend in together and it is a little challenging to really pin the settings down. Just a couple of things that I would be remiss without mentioning: #1 - I wish that there were some kind of instructions included. It took me a few weeks before I realized that the plastic adapters expanded as you screwed them further and further into the barrel, creating a tighter and more accurate fit. So, pick the biggest adapter that fits without being screwed down into the barrel, then fully seat the bore sighter assembly in the barrel and twist the laser body until everything is very tight and secure. Pros probably are thinking "well, duh" beginners might not realize this at first. I didn't. #2 - Check that the laser is aligned out of the box. I fought with a misaligned laser for several months and a decent amount of money spent on ammo before I figured out the laser was misaligned. How do you check? Mount the bore sight assembly into the barrel and tighten everything down like you are going to zero in the firearm. Then, while the laser is turned on and pointed at the wall, twist the laser body 1 full revolution. If the dot doesn't stay focused in one place then it is misaligned and you are gonna have a bad time. The first one I purchased had a laser whose dot would move around in a circle across the wall when I would twist the barrel of the bore sight. Visiofire support quickly resolved it with a new one and without issue. The new one is aligned perfectly. Overall, great buy. It isn't a replacement for going out and doing a final zero check with live ammo but it will get you on the paper and close enough that adjustments are minimal, saving you time and ammo. Takes the guesswork out of things.
