12 Gauge Laser Boresighter

I am really impressed with this MidTen 12 ga Laser Bore Sighter. We mounted a scope on our Remington 870 slug gun after this last deer season and tried to sight-in the scope by simply firing slugs down range. After 2 boxes of slugs we still were a good 10 inches from center. We shifted approaches and found this bore sighter on Amazon and the price was worth a try. The construction of this bore sighter is very heavy and solid. It slid easily into the chamber just like any other shell. With the laser light beaming brightly down range we were able to adjust the scope and had it spot-on in a matter of minutes. We still need to confirm the scope alignment at the range but I'm confident it is spot-on. This was a very good purchase for basically the cost of a few boxes of shells and we have it for future use. I would definitely recommend this bore sighter.

High quality and does its job

Great price. Fast delivery. Nice quality.

The product is nicely made with a heavy brass and fit in my 12 gauge shotgun snugly. It does not have an on off switch and only turns on or off when you screw the head of the shell in to make it go on or screw off the head when you want it off. The shortcut for turning on and off is simply unscrew the upper fourth part, which is easy, and then tighten or loosen the threads far enough so the brass parts stay together.. This way you don't have to take the batteries out and then put in again when you want to use it. The laser only works when the batteries are tight, which of course is what you want.Keep the nice container it comes in and lay it back in the shaped foam insert that holds it.You need to know that the green laser is very good but you won't be able to see it on a distant target if it is bright out. Wait till evening nears, or a very dark cloudy day, to bore sight. A simple method is to bore sight it on an object that is at the desired distance you want it on a darker day. Then you simply adjust your gun sight to the green dot. It is right on then. Saves a lot of time and shells.It is spot on and I am very satisfied with this product. It costs a little more than many bore sighters for a shotgun but you get good quality. I am glad I have it. Only gave 4 stars due to on/off capabilities. Other than that, this product is very good

I am very pleased with this item. I got it to help me zero a red dot on my Mossberg shotgun. The laser was thick and well constructed. It had a nice lip on it so it didn’t go down or get stuck in the barrel. When I racked it actually ejected out. I picked the longest distance in my house to use a spot on the wall as my point of aim and matched my dot to the spot on the wall. Yesterday I went to the range to see how the laser worked out expecting to have to make some adjustments but I didn’t. It was spot on 15-20 yards out. I ran out of time so I didn’t get to try 25 yards. I am very pleased. This is perfect to zero a dot especially on a 12g. Shells aren’t cheap and where I initially had my red dot was no where near zero. I would have wasted a lot of time and money with out this.

Solid with a snug fit. Made from machined brass. The laser is accurate and has good range in dim light (don't try to use it in sunlight).I repeatedly rotated it and re-seated it. The laser came back to the same spot. Used it to align my Romeo5 red dot and was pleased with the results.

Works good was able to zero in red without having to use any ammo. Test shot shotgun is accurate. Fast shipping. Easy setup.

Very accurate bore site, battery lasts a long time and the best bore sight I ever owned. No on/off but just unscrew the bottom a few turns to shut it off. Passed the rotate table to ceiling check test with flying colors. Just wish their .223 bore sight was as good as their shotgun sight.
