Excellent idea, and a must-have for zeroing your rifle
CONSTRUCTION: The laser body is made of sturdy brass, nicely finished, and with an excellent fit for the firearm caliber. The version I purchased is for a .308 Win caliber rifle. The laser is perfectly aligned with the barrel axis, so it won't make fringes once it's manually placed in the chamber. If you follow the instructions that came with the laser you'll zero in your rifle in no time...and without spending a lot of rounds in the process. (A note to semi-auto firearm users, such as M1As: after manually inserting the sight laser into the chamber, do NOT slam the action as you would with a normal round - this will damage the laser. Instead, SLOWLY advance the action until it closes the breech. This note is in the user's manual, too, but it won't hurt to note it twice.) ACCESSORIES: The laser comes with a small holster for storage, made of ballistic nylon. The holster is large enough to store the laser, its batteries and the user's manual. {However, it is small enough to lose it, too. ;-) }. It comes with a set of two button-size batteries (LR 754). Some things to note: - it's not a high-intensity laser. Therefore, you may have difficulty seeing the laser beam at 25 yards in the open on a very sunny day. - due to its size, the laser uses two button batteries (LR 754), and those don't last a long time. My recommendation is to keep the batteries in the provided pouch until ready to use, and to carry a spare set just in case. CONCLUSION: For what it was designed, it does an excellent job. I wish the laser intensity would be higher, or be of a different wavelength (color; e.g. green) for better visibility in bright, sunny light. I will definitely buy it again if I lose or damage it (I hope I won't), provided the company is still there if that happens.

Worked Perfectly
I used this to sight in my .308 M1A rifle. I got a new Vortex scope and a Basset Machine mount for the holidays and took it out to the desert to get it sighted in. I couldn't even get it on paper, so I decided to quit wasting ammo and get a boresight. The Sightmark boresight came with batteries and simple instructions. I put the batteries in and the laser lit up. Once I got it chambered I matched up the laser dot with the reticle and that was it. I did it in the late afternoon so the laser dot would be bright. My aim point was about 20 yards. Of course, at the range I would have to adjust the elevation for shooting at 25 or 50 yards, but windage should be the same. Sure enough, I was on paper and had to adjust the elevation while the windage adjustment was minimal. In sum, this product worked perfectly to get my scope on paper. Some notes: 1) There is no on\off switch; once you put the batteries in and screw on the cap the laser is on. You have to take the batteries out when you're done. They are tiny little things. I used the corner of a plastic sandwich bag and rolled them up in it, and it fit in one of the little pockets in the fabric case. 2) Open the bolt and seat the boresight in the chamber as you would load a single bullet and don't let the bolt slam close as this would probably damage the boresight. 3) This is a low power laser, so you're not going to be able to see it on a bright day at 50 yards. Probably not even at 25 yards. That means you need to use it indoors or at around dusk if you use it outside. Using it indoors will limit the distance you can set your elevation at, but the windage will not be affected. 4) Boresights are not designed to set your scope for the bulls-eye. They help you get close enough that you're hitting your target, and you can go from there to get an exact adjustment.

Boresight itself works well, but it comes with lousy batteries.
Got this to sight in the Leupold DeltaPoint Pro red dot sight for my Ruger AR556 .300 Blackout. The sight itself worked just fine in getting me on paper, its easy to use, just put it in the chamber and close the blot, and it fits in the chamber well. It was decently accurate, I was able to get to zero with about 25 rounds. Although I'm only giving it four stars because it comes with really cheap batteries, they had a very short life span and were drained to the point that I could barely see the laser after 5 minutes of use. I'd recommend getting some Duracell AG3 or LR736 batteries for it if you are planning on using it for multiple guns.

This was perfect for setting my gun. Won't miss nothing this hunting season. The product was exactly as described in the item description. I live in Canada and the parcel arrived at my door in less than a week. I find that to be decent shipping speed. I would recommend this product to my friends and family. I would definitely buy again!
