Sightmark is a good tool and a great value and generally always dependable. I use them in all my calibers, and would use nothing else for a Glock. But the vender in this case is excellent. Sightmark can be had anywhere, trusted venders, sometimes is a different story. Both highly recommended. Keith A Smith

I have tried many other bore sights available on the market, none of them worked out for one reason or another. These sightmark bore sights fit in the chambers of your guns and make sighting in incredibly quick and easy. They may cost you a little more, but they work incredibly well, they are EXACTLY what I was looking for...

After putting 10 rounds in the dirt around the target, I put the Sightmark boresighter in. I adjusted my sights to match the red dot coming out of the barrel. Next 10 rounds were within 2 inches of center and in a 3/4 inch cluster. This at 10 yards with a 3" barrel. This will not have you immediately shooting every round perfectly centered, but it saves ammo and frustration by getting your sights or optics very close without having to fire a single round. I bought Sightmarks for my 22lr and 223/5.56. I will be buying more for my .308, 45acp, 40s&w, and 380acp. They just need to make one for my 10mm now.

Aloha, I have purchased other brands before this one and have been very disappointed with the others. The batteries were too small and hard to load, but not with the sightmark. They had ways of turning the unit off with out removing the batteries but then again it did not function properly. In the sight mark unit the battery has to be removed but, that fine with me. How often do we need to sight in. The battery last longer when removed. Well thanks for a great product !

The bore-sighter is the faster way to set your sights. It beats the trial-and-error methods. Glad I have it. It shines brightly in a tight beam. I have 3 9mm firearms so this has been great. Don't expect to eject it as you would a bullet. You may need to poke it out using a bore-cleaning rod or similar item. You need to remove the batteries to turn it off (no switch). Comes with a little carry pouch.
