SightmarkBoresight with Red Laser

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...

I used this to zero in my pic rail mounted laser sight for my XDM ELITE OSP 9MM. I originally had my rail mounted laser sight zero'd to my iron sights. At 20' the lateral adjustment required was extremely small to align with this bore sight. I have yet to actually go to the range and do a proper on paper zero. When getting this laser bore sight (LBS) into my barrel, I thought I could slide it into my magazine, insert the mag into the Harwell, then operate the slide gently to insert the LBS into the barrel. The LBS was too long for that. I couldn't get the magazine more than an inch into the magwell. So, I locked the slide back, pointed the barrel down, and through the ejector port dropped the LBS into the barrel, then gently released the slide to gently seat the LBS into place. Got my laser dots to align perfectly at 20 ft. Lockung my slide back, the LBS wouldn't shake out. Went to the kitchen and grabbed a clean plastic drinking straw and pushed it in through the muzzle end of the barrel and was able to unseat the LBS with a firm push. After the LBS was removed I put it back in again to confirm the LBS was perfectly on axis in alignment. It was. Wash rinse repeat. Perfect alignment again Apparently I got a good unit. Some reviewers didn't, or perhaps they damaged theirs in the barrel seating process. Who knows? Anyway, it worked exactly as advertised. I would say its a precisely manufactured product. I recommend and would definitely buy again.

I love the idea but there does not seem t be any QA for this product. I received two sets and neither laser was aligned corrrectly. Unless the laser is aligned perfectly within its housing, the laser will not point straight. In my photos you can see how you must check your laser before a) using it to zero your weapon and b) before giving a review or getting rid of the packaging. 1) Remove the barrel from the weapon and clamp it to a flat surface (I used a metal table leg.) 2) Mark part of the back of the laser and consider that part “up” for now. 3) Insert the boresight into the barrel wth the mark in the up position 4) 5+ yards away mark with tape and a dot of ink where the laser hits a wall (this will be the reference point) 5) return to the laser and carefully rotate the boresight (or remove and reinsert) so that the mark you made in step 2 is in the opposite position (down if it was up). 6) walk back to the wall with the tape and see f the laser dot matches up woth the existing mark. 7) Repeat steps 3-6 as many times as you want to validate the result. As long as the dot is in the same position when the mark on the back of the boresight is in a specific position you will know that the barrel has not moved during the process of you removing or spinning the boresight. The point to all of this is that for the boresight (any boresight) to work properly the red dot on the wall should always be in the same exact position no matter how the boresight is rotated in the chamber/barrel. If the red dot does move (in my case it moved about an inch for both boresights) it means any “zero” you were to get by using this thing will be off.. and not even close. If you don’t check your boresight like this and you are still getting OK groups after zeroing your sights there is a good chance that you are not shooting consistently or that you are cheating yourself out of even tighter groups. This test only takes a few minutes and is a great way to ensure your boresight actually works properly. Unfortunately for me, after two separate shipments, each product failed the test. :( Also, if there was some way to adjust the alignment of the laser and it’s housing I am confident that using my testing method we would be able to align the laser and have a great boresight. Unfortunately, it didn’t seem like the tiny screws actually did anything but maybe hold the laser inside of the housing

Works Great however it shipped with two dead batteries. I Knew my holosun was off but I didn't realize it was of by 10 clicks. This laser fixed my issue in about 30 minutes.

After reading negative comments in the review I was skeptical about this 9mm bore sight. I bought a 223 bore sight from them years ago and worked flawlessly sighting in my Eotech, it was dead on out the box. I have 5 handguns with various optics on them that I sighted in already. I was already happy with my zero and wanted to see how close this bore sight was. What I noticed was that my windage was dead center on all my handguns and my elevation was off by a few clicks. I took out the bore sight multiple times and rotated it to see if it moved away from my zero. Every time it was still at dead center and the lazer did not move direction. I was surprised how accurate this lazer is. It was pretty damn close to all my zeroes. I wish I had this from the beginning. It would of saved me a lot of time and ammo. I can honestly recommend this product. P.S. I tested this at 20 yards. I hope this helps

The 9 mm works perfect The .380 Bores Sight that I bought work now I took My Walther a part remove the barrel out of my slide & inserted laser in the Barrel & then removed the laser & inserted a shell and they both fit with the same clearest so I put the and barrel in with the slide with out the sprang & it was still not going flush so I move the barrel in & out and then I seen what was happening the clip ejector was stopping it from going Back the rest of the way. So I put the Barrel and slide assy. Together with the spring, & then slide the assy., back on the weapon. Eased the slide back against the frame and the Ejector was holding it out pulled the laser back out an inserted a shell and it went all the way, so I install the Laser back in pull the slide back and let her and eased it forward slight had a gap so I pull the slide back and let her go, and the ejector when right the bye . So if anything else is need just a very sand on the rim of the Laser and I mean very light . So the error was mine it works and with a little sanding the rim of the laser it ought to work just fine and May any way with out sand ,but I just felt it should have went right bye because the 9 mm did !!! But thanks be to GOD we figure it out. So Sightmark , I owe u guy and An apologize So please accepted my Humble APOLOGIZE. Sincerely, Jack R.

I bought the 9mm SightMark to zero in my Viridian X5L tactical green laser/light ( Viridian Green Laser Sight with LED Tactical Light, with Universal Mount for All Weaver, or Picatinny Open Railed Handguns, Except Sub-Compact Models. ) As you might expect it's a matter of putting the bore sight in, turn on your laser or red dot sight/holosight/scope - whatever sight you use - and your good to go. The laser itself was visible up to 82 feet (25 metres) without problems (this is the maximum distance we shoot at, at our indoor range). As with all red lasers, usage in daylight might be a problem, so I suggest to use it at an indoor range or around dusk. As such the SightMark performs good and is useful. The unit does not have an on/off switch (I guess due to its tiny size), so once you screw the cap on (which holds the batteries) it's on and stays on until you unscrew it again. Note that due to the bullet's trajectory the red dot the bore sight shows you is not 100% accurate. However, for distances up to 82 feet you should not have to worry too much about that with 9mm ammo. So far so good, but the three tiny batteries (AG1, 1,5v Alkaline batteries) that came with the unit are really crappy. Within less that 4 minutes the batteries ran out. However, after a few minutes they worked again. This is due to the nature of how Alkaline batteries work. They loose their voltage really fast and then run out. 4 minutes is way to short to zero-in your gun. If you want better performance, get silver oxide batteries as they do not leak once they get old and have a better lifespan. Prepare for the fact that they are about 75-100% more expensive. All in all a handy, useful tool, but SightMark needs to include better batteries (silver oxide and not dirt cheap alkaline) because it would enhance the "out-of-the-box" experience a lot. For this reason I give it a 3 out of 5. SightMark: if you read this, please deliver this bore sight in the future with better (silver oxide) batteries. For me it's to late but for other customers you should change it.

I'd like to say this proved my sights were off, but it actually proved they were dead on (Smith and Wesson M&P9 2.0). Oh well, I guess I have to learn how to shoot better. This boresight was super-simple to use aside from handling the tiny button batteries and end cap. Fits nicely in the bore and allows the slide to close. One tap and the boresight comes out. The laser pip is very bright (red) and easy to see. Great product Update: I check mine by putting the gun in a woodworking vice. the pip hit the same spot if I took it out an rotated it. Most sights only adjust for windage so you can only adjust side to side, not up and down. If you are adjusting a laser sight, just line it up with gun sights initially and tweak it at the gun range.

S adapte parfaitement , marche mieux ( portée ) quand il y a peu de luminosité ambiante Il n y a pas de bouton marche de arrêt ( il faut retirer les piles pour l éteindre ) Il faut retirer la cartouche manuellement ( l extracteur , vu la forme , ne fonctionne pas ) achetez des piles d avance , contrairement sur à la photo , il n y en que 2 ! L étui fourni est inutilisable ( pas de place pour les piles si elles sont déballées ), prévoyez une petite boîte .

strumento molto utile per azzerare la tua 9mm tempo impiegato 2 minuti. molto facile.
