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.

This is good, small, compact and exactly what it needs to do. A few 'complaints', but nothing earth shattering. -to have this in GREEN so you can tell the difference between the bore sight and the red dot sight. for ease -there is not on/off, its putting the battery in and it's ON. screwing the end cap fully, doesn't mean it's ON, you have to tighten/loosen the end cap "just enough" to have the laser on. Do your sighting, then take the batteries out. -it seats into the chamber VERY well, to the point where I have to push it out through the barrel instead of extracting it from the chamber. Like I said, it does exactly what you need it to do, bright dot. I sighted from ~10 yards/30 feet away, no issues. some odd things but other than that, its a solid buy.

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

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.

This bore sight laser is amazing. Literally within 5 minutes I was able to adjust my sight to nearly perfect and was so easy to use. The quality was very nice. Thank you for an amazing product. The cost was very reasonable and way worth the money! Highly recommended.

Definitely very bright laser, works well, very rugged and sighted in my P-10C well.

This item worked great. It was simple to load in my weapon. It worked as expected.

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.
