Sightmark Pistol Boresight with Red Laser

I recommend using a vise to hold the gun firmly in place for the entire zeroing, so that the "point of impact" revealed by the boresight - marked on a target paper in ink - can remain fixed, the battery can be removed, and the point of the adjustable gunsight can be adjusted (whether red dot or laser sight or barrel gunsight) to coincide with where the boresight was set. It fit perfectly the 38 special it was bought for. I thought it might also fit 9 mm, and even 380 cal - it does not. Strangely, the rim is undersized - the ejector of the revolver cylinder does not catch it to eject it - but I don't hold that against the company; the item works as advertised on what it was designed for. The laser was centered perfectly - straight down the center of the bore - for the 50' distance to the target I wanted: rotations of the boresight within the revolver cylinder produced no visible "circling" on the target. Battery life is not advertised to be long - I think it was to be <1hr of actual "laser on" time - so don't waste time. Take out the batteries when you've learned what adjustments need to be made, replace them only when you are ready to actually verify, then remove them again. It's all easy enough.

I bought the 9mm version. I used it to adjust the iron and red dot sights on a 9mm carbine at 25 yards. The laser is only so bright, so you're either going to have to do this indoors, or outdoors on a less then bright sunny day. My unit came with 2 AG5 batteries. It will also accept 3 AG3 batteries. There is no on/off switch, when the batteries are in, the unit is on. I suggest you take them out when you're done. I had mine running for about 45 minutes on the batteries that it came with without noticing any change in the lasers brightness. After sighting in the iron sights at 25 yards, I experimented by rotating the boresight in the bore 90 degrees at a time to see if the laser was still aligned with my sights. I noticed no difference at that distance. My red dot is mounted on an American Defense quick detach mount. It was interesting and educational to use the laser to sight in the red dot. After my initial sighting in, I used my hand to flex and twist the sight on it's mount while it was attached to the rail of my gun. Guess what? It was clear I needed to tighten my mount! Then I used the laser to see just how well the red dot would hold zero when repeatedly removed and replaced on the weapon. Again, at 25 yards, I couldn't tell a difference. Finally, as I had done with the iron sights, I rotated the boresight 90 degrees in the bore, rechecking it each time against the red dot sight. Everything looked good! After all that, I switched to live ammo to check my efforts. I was off about half an inch high to the right. Fantastic results as far as I'm concerned! I'll sort out the rest at the range. I consider what I paid for this device money well spent for what I've used it for so far. Mine was a tad tight in the bore, even after cleaning the bore carefully and applying a VERY light coat of oil, I still had to use a pair of needle nose pliers to carefully extract it each time I removed it. I don't consider this an issue, just passing along my experience. EDIT: April 10, 2016 - Just a quick note on batteries, The second time I took this thing out to use it, the original AG5 batteries it came with were dead. The laser came on when I put them in but before I could use it, it sputtered out. I had bought a package of 10 Maxell AG3 batteries at the same time I ordered this boresight so I put in 3 of them. They lasted 10 minutes at best! I don't know exactly what to make of this information. Are two AG5s inherently better then three AG3s? Are the Maxells I bought just old or crappy? This much I can tell you, you gotta work quick to get anything done in 10 minutes...

Bought the laser bore sighter for 9mm. Pass this one up. Typical Sightmark QA. Build quality is shoddy, sighter gets jammed in the chamber, requiring a non-marring rod to pop it out. Tried using it, adjusted my red dot, popped it out. For fun, I reinserted the sighter. Off again. Readjusted my red dot. Removed and reinserted again. Off again. Obviously, the laser is off-center out of the box. Returned. Don’t waste your money, just buy a Site-Lite and call it a day. Yes, it’s more expensive. It is also much more reliable, better built, and yields more accurate results.

I bought this bore sight to sight in my new green laser. It worked good to "generally" get the green dot in the right area. You will still need to actually fire some live ammo to do the final adjustments on your laser. Laser bore sights are good, but nothing compares to actually putting some lead down range. Like others have stated in other reviews, if you un-chamber the bore sight and then re-chamber the bore sight, your red dot WILL be off a little bit. At 21 feet, mine was off by 3" on an indoor wall target. So what I ended up doing was to actually do multiple "sights" on the wall target from 21 feet. I would sight in the green laser aligning it with the red bore sight laser, then mark on the target with a black marker the exact point it touched (helps to have a second person to mark the black dots), then un-chamber and re-chamber the bore sight and repeat this 5 times. I ended up getting the green laser and red bore sight laser within 1" no matter where in the barrel the red bore sight was. And now, take it to the range and fine tune your green laser. I gave this bore sight a 4 star rating because of the inconsistantcies in the laser position. This tells me the red laser is not perfectly inline with your gun barrel. This bore sight is pre set from the factory and can not be adjusted. It is close, but it is not spot on. For the price, I guess I can't complain too much! I do recommend this laser, but if you want one that is more precise, you are going to have to fork over a lot more cash. CPS

These work great. Let’s be honest here, stop buying the super cheap ones and hope they work. I had to buy 2 other ones before this one because they didn’t fit right or the laser was junk. 100% recommend other the other brands.

Bought this for my BRS99 9mm and it worked as described on ad. I buy a lot of Sight-mark gear because of the quality and the reasonable prices like the Reflex Sights that are every bit as good as reflex sights @ twice the price, everything I have purchased from Sight-Mark has worked fine and keeps working when needed as long as you take care of them as described by Sight-Mark. Removing batteries proper storage just common sense kind of things. Also they back up their products along with Amazon's A to Z guarantee. So in my humble opinion you can't go wrong with a Sight-Mark product. But don't get me wrong there are other products that are built better for specific applications and do cost more and in some cases you are only paying for the name as I'm sure Sight-Mark would have a product for the operation you would need an optic for, case in point Mil-Spec.
