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

I have a laser sight mounted and I’m fairly good at setting the initial MOA of my sights off-range. I generally need to tweak and make adjustments at target practice. I bought this bore sight to make those finer adjustments off-range, instead of wasting valuable range time and spent rounds fiddling with tools. I’m well aware that a laser sight mounting should only be used to assist with quick target acquisition. Do not rely solely on the laser and always be aware of the environment beyond your target. With that said, by placing the bore sight in the barrel and powering up my mounted sight, I can chose a typical defensive distance (say 7 to 10 yards) and align my mounted sight so the dots come together as one. Pay attention to how the light is seen through your standard sights, as this will help you understand how to align your eye when you are not using the laser. The same methods can be used on carbines and other long barrels with scopes, choose your distance and align your scope accordingly. Also take notice of how the two lasers separate as you draw nearer or farther from the distance you used for calibration. Remember windspeed, weather conditions, and the weight of your round all have an effect on trajectory over longer distances, where lasers generally project in straight lines. Although, it can be a pretty cool light show shinning a beam through heavy rainfall, but be smart. Don’t shine lasers near traffic or into the sky as they can temporarily blind and disorient drivers and pilots. It’s also illegal. The 9mm bore sight comes with 4 pairs of batteries, if kept in a cool and dry environment they should last a long time. The laser becomes active as soon as a pair of batteries are inserted properly. There is no on-off switch and when you are finished using it you will need to remove the batteries. You may need to use a ramrod to eject the bore sight from the chamber, but be sure to use a soft or smooth tip to avoid scratching or damaging the optics of the bore sight. Also, take care not to get liquids or powders on the laser lens as this can damage the device. A foam slotted storage pad for the batteries is included, but a note to the manufacturer if reading this, an additional chamber in the foam pad to place the bore in would be nice. I’ll be storing my spare batteries and the sight together in an old water tight pill case that just happened to be a perfect fit.

This thing is freaking amazing! It worked perfectly for me at the range. I won’t lie sometimes it does have issues being loaded but once you clear it, it’s totally fine! I was able to get my green dot and focus perfectly and for the price of this I can’t complain. I would definitely recommend this for anybody. And the brightness of the laser is very strong.

So far so good. Can hit a target at 30-40 yds with my red dot sight now. Pretty close groupings at about 15 yds. Very good for the price point. Work quick however, or those batteries drain.

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.

great value, easy to use. 300 blackout, chambers good, easy to see on target. once you have sighted in your optic, you're more than just on the paper. you're ready to work on your grouping. has good range and visibility. thanks.

Excellent and affordable bore sight. Zero’d in seconds.

Works as it should and easy to install batteries. And it came with plenty of spare batteries. Worth the 10 dollars to sight in any red dot so you don't spend more money at the range.

Good bore laser for the price. It helped me sight in my new scope quickly and saved me time at the range. The laser was bright enough to see clearly and fit well in the firearm I used it with. Easy to use and accurate enough to get you on paper fast.

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

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.

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

as advertised.

Great product very accurate sighted in at 10 yards and was pinpoint accurate
