EZshoot Bore Sight Laser 9mm/ 223 5.56mm/ 30-06/25-06/270 /300BLK 7.62x35mm/ 6.5CM/ 12 Gauge Cal Red Laser Boresighter with Extra Batteries

Works fantastic! Was able to line up my red dot on my gun perfectly. Super quick, super easy. Just make sure you have something thin to push it out of the breech since the extractor doesn't seem to grab it.

Easy to use and makes zeroing in your red dot very quick. Used this on my S&W Equalizer to zero in the CT laser that came with it, and also the PA Green dot I mounted. When I took it to the range the accuracy was dead on and I haven't had to any further adjustments. Also liked that they includes extra batteries, though I doubt I will run the laser light that long to run down the batteries, its more likely they will eventually die from sitting around for a long time unused.

As a firearm enthusiast, ensuring that my guns are properly sighted is essential for accuracy and safety. That's why I recently added the EZshoot Bore Sight to my collection, and I couldn't be more impressed with its performance. First and foremost, this boresighter is incredibly easy to use. With its red laser technology, it provides a precise and reliable method for sighting my 9mm and 5.56mm firearms. Simply insert it into the barrel, turn it on, and adjust the sights accordingly - it's that simple! Within minutes, I was able to achieve perfect alignment, saving me both time and ammunition at the range. The build quality of the EZshoot Bore Sight is exceptional. It's sturdy and well-made, with a durable construction that can withstand the rigors of regular use. Plus, the compact design makes it easy to carry in my range bag, ensuring that I always have it on hand when I need it most. I also appreciate the inclusion of four sets of batteries with this boresighter. It's a small but thoughtful detail that demonstrates the manufacturer's commitment to customer satisfaction. With plenty of spare batteries included, I can rest assured knowing that my boresighter will always be ready to go when I am. But perhaps the best part about this boresighter is its accuracy. The red laser is bright and visible, even in broad daylight, allowing for precise adjustments in any lighting conditions. Whether I'm sighting in a new rifle or fine-tuning the sights on an existing firearm, I can trust that the EZshoot Bore Sight will deliver consistent and reliable results every time.

Great product. Works as intended, plus it is very accurate. My only issue is that sometimes it gets really stuck in the barrel of my gun. I own a G19 gen 6 with a stock barrel, I can’t speak for other guns. Other than that I would 100% recommend this item.

Simple to use, only drawback is you have to remove batteries to turn it off, not a big issue since your only using it to zero in your optics.

I read some negative reviews and decided that I would try it and decide for myself. Besides, for the price they're asking, I would just throw it out if it was garbage. Anyway, the quality of the one I recieved (the 9mm) was very good. It fit the chamber with the slide closed and the threads were fine and worked perfectly. Comes with 8 batteries but you only use 2. Make sure you install them properly, with the positive (+) side facing the screw cap. Read the battery for plus or minus, may be confusing when you compare it to a regular battery. I had no problem removing it. Just shook the gun and it fell out. I lined up the red dot with the iron sights and it was almost dead on at about 30 feet. Still haven't tried the new gun at the range but this bore sight tool is to get you on the target, NOT TO SIGHT THE GUN IN PERFECTLY. Overall, it worked out well for me. I would recommend this product. I WOULD NOT squeeze the trigger with the tool inside the chamber. It may break your striker pin or firing pin. I'm not going to find out.

Works great, fits and came with batteries plus 3 sets of replacement batteries. Would definitely buy again.

Worked perfectly and fit snug in my sub-compact (P365). The laser is bright and stable. The round also has tiny jeweler-sized flat-head screws to adjust the laser if it doesn't already arrive centered. You can test it by rolling it on a table, and shining it on a wall. I might have to buy the longer 9mm one for my full-size because it is loose fitting in the chamber.

Works as expected. Sometimes gets stuck in the rifle, so I use a cleaning rod to poke it out. No big deal as I usually have one in my truck, but if you don't have something to poke it out with, it can be tough to extract.

I'm sure that part is my fault. But to label it 9mm/223 usually indicates it somehow does both. If you sell another product that covers the other bore size, label that product separately. It just convolutes things for new firearm owners. I was obviously expecting more than was possible. But naming it like that is misleading. Product wise, my first thought is, no power button? Even if you put a hole for a paperclip on the side where the button could be housed, at least it's something. Taking the batteries out then back in, then out again...really? There are enough loose bits and bobs to worry about with firearms. Don't add to it for Pete sakes. Overall, 3*'s for misleading product name and poor design.

Works as intended. Zeroed right out from the box, good distance coverage.

as advertised.

Poor design. The only way you can remove it from the chamber is by using a cleaning stick. Had to return it.
