Followed the directions for initial set up fired and was within about 6" at 100yds. On the second gun took care to rotate device in 90 degree increments to find the approximate center zerod the scope and first shot was about 2" high and right. I think it has to do with the way the plastic inserts fit the riflings/flats, but 2" at 100 yds. is pretty good. you will pay for the device in bullets."

So I purchased the laser bore sighter from this company, last fall I thought. I did my research and found out that the fastest and most efficient way to mount a scope on a rifle accurately without using a ton of ammunition or sending my rifle away for a week. Was to get a laser bore sighter. So I ordered one and it came before the expected delivery date. I sighted in my scope at the beginning of the year and it worked like a charm. I was able to hit the target on centre at 200yrds. Last month my father passed away leaving me his rifle that he’s been wanting to sight in since I bought the laser. Upon going to use the laser I noticed the bore adapter was mangled and cracked from me being too aggressive and not paying attention. So I immediately reached out to 24hr customer service from the warranty card they give you in the case. I will admit I was kinda bummed out at first. But after sending them a email and explaining that I broke the adapter being reckless. I was emailed back by Lee asking if I could find my order number. After searching for twenty minutes I finally found my order which was not from last year it was from 2023. Way passed the 6 month warranty they provide you with. I noted that it was past the warranty time limit and that I was willing to purchase them. They told me that they were going to send me the replacement adapters anyways and proceeded with giving me excellent customer service. Finally I got the new adapters and they now come colour coordinated and they’re twice as thick and durable as the original ones. I reached out to him, to thank them and he told me those are the new adapters that come with the laser bore sighter. He also sent me another adapter to replace the one I broke. Honestly I can’t thank them enough. I appreciate the company and Lee for the amazing customer service. If your in the market for a laser bore sighter I would recommend this company. 👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

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

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 great inside and on a cloudy day or somewhat overcast. Not so good on a bright sunny day.

I love the product and the case is nice. The only problem was it came without instructions. I was sighting in a .22lr pistol and couldn't figure out how to use it. I emailed the vendor and he replied the same day. He emailed back the instructions which I have added to this review. Once I understood about the ribs on the smaller adapters I was able to identify the #2 right away and the setup was easy. That was a pretty good design solution.I haven't been to the range with the sighted gun but I tested the bore sight with a 9mm I know to be accurate and it was right on. I also have another 9mm bore sight, the kind you put inside the barrel from the chamber side, but this one has two main advantages in my opinion. First, you don't have to strip down the gun to insert the device into the barrel and then again to get it out. Second this device works on a multitude of calibers. I wish I'd bought this one first because I'll never use the other one again.

Wow this works! Instead of buying individual $30 bore sight lasers for each caliber, this all in one set has worked great for me. I have sighted in 1x 10-22, 3x 5.56, 1x .300 AAC, 1x 10mm and 1x 9mm. Each and every one shot very close to point of aim in the field. If you’re concerned about your concentricity, install this laser in bore and gently spin it while it’s seated. If the laser dot stays put and doesn’t run a circle as you turn the unit, you probably have good concentricity.I love that I don’t have to spend tens of minutes sighting in firearms in the field when I want to be spending time shooting drills.The only issue is that it can be difficult to determine which bore insert belong to which caliber and there are maybe 13-15 inserts in a baggie. The numeric designators on the inserts can be very difficult to see and read, especially on the smaller inserts. Once you figure out which ones you need for your calibers, mark them yourself and separate them from the herd. That way you wont have to dig through them all every time.I’m very impressed with this device. Oh, green laser is very bright! If you are sighting in reflex sight/RMR sights, try to get a different color bore laser dot so you can tell the bore laser from your dot. I was still able to sight my green dot with green laser but it’s way easier when they are different colors.

Here are the pros and cons of this product. The pros are it looks like it’s very well-made, and it comes in a good storage case with all the adapters. This will get you on your paper target, but this is definitely not a one and done.The cons are the adapters that screw on the back of the laser and what is inserted into the barrel are not clearly identified on the pieces themselves so it take you a few times to figure out which one is the right one for your barrel.The second con is when I inserted the bore scope laser and the on and off switch that is on the laser was facing to the left. I would zero in my scope. Then I rotated the on and off switch to the right side and looked through my scope again, the laser was all the way on the other side of the scope. So that’s why I say yes this will get you on paper, but it is not accurate.This was all done at 50 yards, which was about 4 to 8 inch difference all a round, on paper target.If you’re going to use this to set up a scope and not remove it, this might be a good product for you. If you’re going to switch between a scope and a red dot optics, I don’t think you’re gonna be happy.

Fellow shooters, I normally don't write reviews but felt this was worth the time to do so. I have had many bore boresighter’s both chamber and muzzle type over the years. both my own and friends. The first thing I do with them is to put them in my metal lathe chuck and give the chuck a little a spin. Many, at only 20 – 30 feet will draw a circle a foot diameter on the wall, totally useless. Obviously never calibrated from the factory. I took a chance on this one and was delighted to see it was dead on! So no matter how its inserted in the bore I know its true. Very well built and will likely be the last one i will ever need.

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.

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.
