MidTen Red Laser Bore Sight Kit Multiple Caliber for .177 to 12GA Caliber with Big Press Switch Red Dot BoreSighter with 2 Sets of Batteries

Lazer worked very well and was high quality

Easy to use. Lots of includes adapters for every caliber. Was able to bore sight a .223 rifle and a 9mm pistol with no problems. The laser is strong enough to see in daylight. Would buy again.

Works great if you know how to tune the adapter. You will have to discover that the adapter is screwed on a cone-shaped end of the device. As you screw the adapter on the rod, the cone forces the adapter's arms to spread, increasing the adapter's diameter. This is how the adapter's diameter is tuned to match the exact diameter of the bore. Until you learn this, your impression will be that the adapters are either too loose or too large to fit in the bore.

So far so good , it really helps me sight in a few of my rodent relocation alarms

I love the product, the arrival time was just not acceptable. But, all in all I got my purchase item and I’m happy with it.

Got it today and used it on my .177 pellet rifle that I just put scope on. Wasn't exactly dead on , but pretty close. Took about 9 shots to get it dead on . Saved a bunch of time and trouble because scope was wayyy off!

Horrible waste of money laser does not stay on with batteries lol waste of money i hope amazon removes this product because there scamming everyone and the laser is not even accurate when i did get it on it was off so much

This set is the easiest & cheapest way to perfectly align & sight in scopes, sights and/or lasers with the barrel for perfect accuracy. You simply change the end for the caliber you need & insert into the end of the barrel. If you have more than 1 firearm or have anything that has optics or targeting aids this is so much easier, faster & cheaper than buying bore sight rounds for every caliber you own. (Bore sight is a bullet casing in the caliber you firearm takes, in place of the actual "bullet" is a laser emitter. This allows you to load it into your firearm like a normal bullet & have a red laser beam shooting out of the barrel. You can then adjust your optics and/or sights to align with the red dot.)

Can't wait to see on traget how close it is .

Pro kit!

Bonne qualité mais précision mon certaine.

Does a great job and has multiple options to fit different barrels.

the entire battery system needs a complete rethink and overhaul. currently, the way it stands, it is nearly impossible to deal with the batteries once they run down. And they run down. Far too quickly in humble opinion. I have cat playtoy lasers that use the same quantity and number of LR44 cells and they run for hours before I have to change them. granted, they never are used in bright daylight nor for distances greater than 20 feet so the cells in the boresighter are doing far more, operating at high noon (sometimes) and working with objects a solid 25 yards away, sometimes more (at night 50 yards is common)
