Brand new AR12 with new optics. Aligned the optics to the beam at night as to see the beam at greater distance. Tweaked the optics to get dead center at 50 feet and waited till morning. Brand new shotgun and optics and nailed the target on first shot. Couldn't be happier.

I recently purchased the 12GA Red Dot Laser Bore Sight, and overall, I'm quite satisfied with its performance. This tool has significantly simplified the process of sighting in my shotgun, making it easier to achieve accuracy right from the start.The setup is incredibly straightforward—just insert the cartridge into the chamber, and the red dot laser projects a clear point for alignment. This feature has saved me a lot of time at the range, allowing for quick adjustments without the hassle of constant shooting and resighting.The laser is bright and easily visible, even in daylight, which is a huge plus. However, I did notice that the battery life could be better; it seems to drain a bit faster than I would like, so I recommend keeping spare batteries handy.One minor drawback is that it may not fit perfectly in every 12GA shotgun, so it’s important to check compatibility. Despite this, it has worked well with my models.In conclusion, the 12GA Red Dot Laser Bore Sight is a valuable tool for any shotgun owner looking to improve accuracy. It’s easy to use and effective, earning it a solid four-star rating from me!

While this works as described, and seems to be accurate (haven't been to the range yet), the instructions say to unscrew the battery cap a bit to turn it off. Nope, it does not turn off, as the batteries still touch the sides of the battery compartment (which is connected to the (+) of the circuit. Thus, you have to completely unscrew the cap and remove the batteries to turn it off. A minor annoyance, but otherwise it seems to work well.The instructions also say to not close the breech, because the extractor could damage the item. But without the breech closed, the shell is loose and can move in the chamber, and can therefore not be considered to be accurate. I noticed no damage to the device when ejecting the shell by normally racking the ejector mechanism, so not sure what they are on about.

The manufacturer definately had the right idea. It's perfect - except for the batteries. You have to remove them to turn off the diode, meaning they will probably separate at some point. With a little better enginering, loosening the two main components could work much better than it does currently.Still a good value overall and easy to use.
