Boresight

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

Da man die Verpackung aufschneiden muss ist eine Retournierung nicht möglich. Zur Funktion: kann ich keine Angaben machen, da außer ein roter Halbmond nichts zu sehen ist. 😵‍💫

Bei meiner Lieferung, ist der Laser nicht mittig in der Patrone (Qualitätsproblem) somit erhält man schon auf 3m unterschiedliche Trefferbilder je nachdem wie Laserpatrone im Lager liegt.Damit ist der Zecks des Produktes nicht erfüllt

Sehr ungenau. Auf 7m ca. 10cm Abweichung.

Le laser n’est pas apparent à 20 mètres.

Tut gut was es soll, ordentliche Präzision

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.

works great, nice and bright, easy to put in. 4 Stars due to no on/off switch (have to remove the batteries to turn off), and a little hard to get out once in the chamber, needed to push it out with a bore cleaning rod.

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...
