Reviews & Ratings for SightMark Triple Duty Universal Laser Bore Sight — 138 reviews — Page 1

This bore sight is way off, not even close to zero. I started bore sighting my rifle and could not see the dot on a three foot target at 30 yards. I thought perhaps it was too bright outside so I moved the target to 10 yards and could see it on paper. The cross hairs in my scope were about a foot away from the red laser dot. I thought that was crazy... no way my scope could be off that much. I decided to rotate the laser while attached to the barrel to see if it stayed centered. Instead of remaining centered, the red dot started making an ark while rotating and completed a 12 inch circle on my 10 yard target. I would send it back however I mistakenly threw away the packaging and Optics Planet will not allow returns without the original package. I think this one is probably defective- likely a quality control issue.

There are multiple versions of this particular bore sighter available and I didn't understand the subtle difference between them when ordering. However, after receiving and using this product, I've come to the realization that there is a considerable weakness with the SKU I purchased. The version I bought does not have a centering arbor. The magnet had etched concentric rings to help with alignment but no proteuding arbor to make it easy. This wasn't too big of an issue with my rifles, but getting the alignment on a pistol was much more difficult. My advice is to purchase carefully to not waste shipping and time on a device that may not meet your expectations.

Retired 74 Y/O law enforcement officer. Been hunting, fishing, shooting, camping in Colorado my whole life. LOTS of shooting. Prefer old military guns and open sights. But even original sights can be off. And use scopes for big game for clean, one-shot kills. Have tried a lot of bore sighters. This is my second SightMark. Their products are the best and most accurate. Not sure why they call this a Triple Duty, but it is bright and easy to use. Got rid of all my other bore sighters and use this one exclusively. From 22 to 5.56 to 458 Win Mag. This has always got me very close to the "X" on the target with the first shot.

Works good,green laser is really brite. Magnet could be stronger if the retractable tip was a magnet. Be careful when using on cerekoted objects, a bump it my fall off. Is good & versatile overall.

When is bright light outside you can't see this thing passed about 20 yards also it is hard to center up in the end of your rifle other than that it looks like a quality made product but it just didn't bright enough and the sunlight

I bought this bore laser, prescription said you can see it up to 100 yards you can't even see this thing up to 30 yards I tried sighting in at 50 yards and couldn't even think about seeing it moved it to 30 still couldn't see it I have aiming lasers on my guns that I can see out to $100 so this product is not as advertised Bruce

Fits all my guns & laser is bright. Prefer over bore sights in chambers.

Excellent product works as it should and made very well

Went back and forth with Sightmark. Sightmark advertises the product as working with all rifles/pistols. My 22LR has a stainless barrel. Other magnets stick just fine, but the magnets they use in this one are very weak and therefore will not work on ALL rifles/pistols as advertised. Sightmark support is terrible and I wasn't even sure at first I was talking to a person in the USA. They tried to explain to me how my gun is designed assuming I didn't know my faux suppressor had to be removed. After wasting my time with that response, I explained how the product falls off when the faux suppressor isn't installed. They then tried to explain that my barrel is non-ferrous stainless steel (pretty sure that doesn't exist, all steel contains iron to some degree). Regardless, I sent them a photo of neodymium magnets sticking with no issues even though they said those types of magnets don't work on stainless steel. There are other issues with this product. The arbor that sits in the barrel sits differently depending on the crown or rifling it makes contact with, producing a 2" MOA depending on how the boresight is rotated, so there is no way to know where the product should sit properly for a good sight.

I bought the green laser and find it very useful. I check and adjust my sights indoors with this bore sight and find it to be very close once I get to the range. Sure beats starting completely off target and trying to guess where your bullets are straying. So far I have been within 3"-6" from target center with new mounts and closer with existing mounts.
