Red Laser Boresighter for .17 to .78 Caliber

I found this for the price to be the best bore sighter I've had.It put u more than on paper at 50 yards even w a rim shot rifle. Very accurate for a 2 shot bulls eye.The Lazer is super fine an not blurring at long ranges an can be seen well during day time at 100 yards also

I ordered a kit out but had low expectation. My caliber, .204, was not in the listed range of calibers the various adapaters. The .22 was too big, the .17, too small. I then bent the tabs out on the smaller adapter (.17) and the light went in tight and stable.I measured off to our back fence, 54 yards, put up a small target for better visibility, and positioned the CLEARLY VISIBLE, green dot in the center. Looked through the scope and needed three clicks up, 2 clicks right, and bullseye, green dot and reticle were all centered. My scope had stayed much better aligned than anticipated.This process took less than five minutes. Green was highly visible in bright sunlight. Of course, at the range I’ll zero scope at much longer distances, but now I’m certain I’ll be on paper. Bottom line: Works well with 204.

I am very happy with this product. Unlike older reviews my kit came with detailed instructions along with 4 color coded adapters inside a ziploc bag with sizes per color. I haven't sighted in my rifle and handgun yet. Nence the 4 stars. Once I use this to sight in my firearms I will update my review.

Inexpensive, very bright green laser light and fits barrel well.

This bore sight tool allows me to easily see the difference between the bore sight with the green laser dot and the red dot of the sight I am adjusting to the point of aim of the barrel. The green dot is very bright and does not look washed out like my red laser bore sight tools. It is a great improvement. The tool is easy to use, and has plenty of adapters for different bore diameters.

I got the green laser to differentiate from the red dots I have. This device has many plug sizes that allow for any size round you can think of. It's even color-coded for grouping the scale of sizes. Do not lose the chart otherwise it will not be as clear.I used this device to Boresight several pieces. I can tell you that I only needed minimal adjustments at the range. I even had one rifle that was so accurate my buddy thought I had used it before. I told him the rifle was brand new and I was hitting old HDDs from about 15 yards away. I went to about 30 and was able to compensate slightly and still hit them.It comes with 2 batteries and it's best to keep them out of the device when not in use. Even when off, corrosion can occur on the contacts. I would recommend it highly especially with larger calibers or even less popular calibers. At more than a dollar a round, it could pay for itself in no time.

Works perfectly

All in all, for the money- this was a good deal. It got us close enough to at least get on paper when we went to the rifle range we fine tuned from there

None of problems noted in reviews of similar competing products: The (green) laser is very bright and easy to see even in daylight. The laser is well centered such that the beam does not move at all when BoreSighter is rotated in the gun's barrel, The barrel sizing inserts are very easy to adjust for a snug fit. Thoughtful touches: supplied with a very sturdy and functional case, 2 batteries (one extra) and small Philips screw driver. Made boresighting my rifle with a new optic extremely fast and easy. Could not be happier.

Good price - fast shipping - easy to use

No regrets buying this bore sighter. Good price and great quality.;

I love that I can use this for every setup I have. It comes in a solid case with foam inserts to keep things from getting damaged. The adapters all have numbers on them so you know which one to use with which caliber, apart from the four smallest ones and they have notches on them because a number wouldn't fit in a way that would be legible.No instructions came in the box, but it is pretty self explanatory and there are lots of resources online to help if you get stuck.I got the red laser, and I think I should have dropped the extra few dollars and got the green one as everyone says that it is easier to see. No problems with the red one so far though.

let's start with the fact that boresight is never exactly on zero, but this one comes very close. It fits nice and snug as long as you follow the instructions, the lines on the side should be aligned in order to get it rite. The dot itself is a bit blurry "probably the dot is about 3 MOA" but still works well. I had to install red dot TRS25 on my Henry .22 model 001 ( too old for the iron sights. lol ) , so first I mounted the boresight, checked it with the iron sights and it was perfect, then mounted the red dot and walked the red dot to align with the green dot " the boresight is green" at about 15 yrds. At the range on paper at 20 yrds I was 3/4" down and 1/2" to the left. Keep in mind that every optic needs precise zeroing for the first time at the range, so over all this bore sight saved me a lot of time and rounds. I definitely would recommend it, even though the one i got the .22 insert was obviously used before, but didn't want to bother with returns since it works very well.
