What is the SIGHTMARK - Universal Laser Boresighter?
Compact, self-contained boresighting system projects a bright red laser beam aligned with the bore axis for sighting scopes, holographic red dot sights, and “iron” sights to the point-of-aim without firing a shot. A powerful magnet holds the sighter securely on the muzzle of any rifle, pistol, or shotgun; nothing to insert into bore or chamber. Install the three batteries (included) into the battery compartment, use the centering guides on the rear of the boresighter to center it on the muzzle, and switch on. Aim at a target 20-30 yards away, and adjust windage and elevation of the scope or sights so point-of-aim is zeroed on the dot. Go to the range for test shots and final sight adjustments. Fits easily in pocket and includes padded nylon carrying case. SPECS: High-impact polycarbonate, black. Laser wavelength, 632-650 nm. Sighting range, 15-100 yards. Dot size, 2” at 100 yards. Includes (3) AG13 button cell batteries, nylon carrying case, and instructions.

Reviews Summary
The UNIVERSAL LASER BORESIGHTER is compact and reasonably priced, but many users struggle with its lack of alignment features and centering accuracy. While some find it useful for initial sighting without wasting ammo, others deem it ineffective due to a weak beam and poor magnet centering. Generally, it serves its purpose with limitations.
What Reviewers Are Saying
Alignment and Centering Issues
60%
A recurring theme in reviews is the difficulty users face in properly aligning and centering the boresighter. Many customers express frustration over the lack of a self-centering feature, which leads to inconsistent results while sighting their firearms.
Functionality and Performance
50%
Reviewers note that while the product can help get firearms on paper at specific distances, its accuracy and overall performance are not reliable. Some users achieved satisfactory results, but others found it nearly useless, particularly in outdoor settings due to a weak laser beam.
Value for Money
40%
Several users mention that the boresighter is reasonably priced and serves its intended purpose without wasting ammunition. However, this low price also comes with limitations, and some reviewers feel that it does not deliver the level of performance expected for serious sighting.
Ease of Use
55%
The ease of use is frequently highlighted, with many users finding the process of using the boresighter more challenging than anticipated. The reliance on a flat magnet and manual adjustment contributes to difficulties in achieving accurate alignment.
Weak Laser Beam
30%
Multiple reviews point out the weak laser beam, which limits visibility in various settings, particularly outdoors. Users find this aspect problematic, as it hinders their ability to effectively use the product.

Better than most
I have used both versions of this boresighter, this one with a flat magnet (this one) and the other one with the self centering device. This one works well but compared to its self centering big sister is much more difficult to use simply due to the minor difficulty of centering to the rifle/pistol bore. I have used these on all varieties of firearms, rifles, pistols and shotguns with great success. When used properly definitely will put the firearm on paper at 25 yards for the average shooter. I only give it 4 stars due to the centering issue

Great Sight in Tool
This tool is reasonably priced and does the job you need it to do without wasting ammo at the range getting your gun on TARGET. I use it for my rifles and scope sight in to get on paper at 50 Yards (Never been an issue and I've used it many times). Always within 8 inches of center. Again - not intended at this price to be a paper puncher ragged hole sight in. I'm pleased with it for the price.

Does exactly what I need it to do.
I understand the other comments concerning centering - it is pretty rudimentary, especially for small bore guns. My purpose is to train myself in my proper "cheek weld" on the bead-sighted 12ga buttstock. The sighter repeatedly centers very well, and gives me the information that I need without expending ammo. When placing it in the storage pouch, one needs to be careful that it is not mistakenly switched on - it is best to reverse one of the batteries to disable it. When I respond to the "recommendation-to-friend" part, it will be in relation to my particular use.
