Chamber-Mounted Laser Helps You Sight In Rifle Or Pistol Without Firing A Shot
Easy-to-use, self-contained boresighting system fits in the chamber of your rifle or pistol and projects a powerful red laser beam aligned with the bore axis for sighting to the point-of-aim without firing a shot. Works with scopes, holographic red dot sights, and “iron” sights. Durable, machined brass housing looks like a cartridge case but actually contains the entire laser system and batteries. Insert the batteries and screw the cap on the housing to turn on the laser; remove the batteries to turn off. Insert the entire assembly into the chamber, gently close the action, and aim at a target 20-30 yards away. Adjust windage and elevation of the scope or sights so point-of-aim is zeroed on the dot, compensating for sight offset to prevent gun from shooting high. Go to the range for test shots and final sight adjustments. Store boresighter in the included nylon carrying case that fits easily in a pocket, tool kit, or range bag. Available in a variety of calibers, listed below.

Essential item(19/10/2021)
Recently got a new scope and was struggling to get it even vaguely on point (were talking 20 minutes of not being able to spot the point of impact).
Finally remembered I had one of these, popped it in, and got the scope dialled in after 2 minutes.
Buy it, get spare batteries, leave them in your range back - one day you'll be damn glad you bought it! Fantastic bit of kit, cannot recommend enough.
works like advertised(31/03/2014)
tried it in a .22 mag revolver. sighted right were the open sights aligned.
Excellent(26/03/2016)
Got my iron sights zeroed fairly easily. Just pop in the batteries, pop it in the chamber and close the action and you're ready to go. Takes the guesswork out of trying to put lead on paper.. saving you precious ammunition in the process. 10/10 would recommend.
Works great.(07/06/2010)
I used this product when I installed sights for the first time on a 1911 I built. It was easy to use and the price was right. It was a quick and easy way to get my sights lined up with out having to fire a single shot and when I went to the range there was no additional adjustments needed to my sights.
Boresighter test(07/02/2013)
Noticing a negative review of a Sightmark boresighter (for a .40 Glock) I decided to test my own .45 Sightmark to see if the beam was in alignment with the case (and barrel). I marked an index on the rear of the case and set it in a sturdy cradle with the index at the 0000-position and projected it at an indoor target 18 ft away, and marked the spot. I then rotated the boresighter index to the 0300-position and marked the spot. Thence, the 0600- and 0900-positions. The average deviation from the center of the pattern was 1/8", indicating a possible error of 0.033-degrees of arc. At HD ranges, that is probably acceptable, but I would recommend buyers do their own tests and return the piece if the results are not acceptable for the required use. I agree with others that the original batteries are not too robust, and premium batteries are in order as the laser's draw is significant.
Subsequent Test(s)(10/02/2013)
I had previously reviewed the .45 ACP Sightmark after testing mine. I found its alignment was 0.033-degrees in error, and gave it three stars. Curiosity remained, so I re-tested over a longer distance and with better lighting and marking controls. I now find the average columation error to be only 0.0124-degrees, and I would now give it four stars. My previous comments remain as before.
Defective Product(08/08/2015)
Tried the boresight with my Colt 45 1911A1 which also has Crimson Trace grips. The boresight was way off target in reference to both my iron sights and Crimson laser which has been sighted in to the gun. Not sure how this product could get any review other then do not buy the product.
DON"T DO IT!(19/06/2010)
Picked this up for my Glock 23, that I just installed adjustable Meprolights on, thinking I could fine tune with it. The pistol was shooting a little low and to the left. According to this it was shooting waaay high and to the right. Adjusted the sights anyway, and was missing the target completely from 7 yards! Don't waste your money!
Good Laser Boresight(24/05/2011)
Works as advertised. Good from 30 to 50 yards. Works best in low light setting. The batteries that are shipped with laser are not long lasting. You will want to order replacement after you first use the laser. These batteries (AG5) were not available locally to me. A google will show many sources. Get the lithium grade. I gave it a 5 star since good batteries make it very good.
BEST PRODUCT ONE COULD INVEST IN.(15/08/2011)
MY RIFLE DID NOT COME WITH ANY SIGHTS AND THIS PRODUCT WAS RIGHT ON THE MONEY PLUS OR MINUS A FEW TURNS.
Nice product!(31/10/2009)
Great for dialing in your tactical optics, holo, lasers, etc.
