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've been losing my mind trying to find a cartridge bore sighter that actually fits my pistols. Those long "insert" styles? Hard pass. Enter this little red beam of joy. Maybe the stars aligned, or maybe I just got extremely lucky, but this laser was perfectly centered right out of the box. I gave it the ultimate test: inserted it, removed it, gave it a twist, and repeated the madness multiple times. Bam. Dead on point, every single time. It holds true better than my dog holding a grudge over a fake throw. My only gripe? The batteries. If you have big hands or fat fingers, prepare for a minor surgical procedure. Putting these microscopic batteries in and taking them out is a hilariously frustrating struggle. Do yourself a favor and keep some tweezers nearby so you don't throw it across the room in a fit of rage. Worth it? Absolutely. It saves ammo, saves time, and humbles my giant hands. Highly recommend!

Solid little bore sighting laser and a good value at less than half what the local gun shops want. Packaging was nice and the laser itself seems to be a solid heavy duty piece of brass, not some thin sheet metal stuff that would get crushed in the bore accidentally. Its accuracy seems spot on. Got my red dot optics lined up first try.

This has chambered flawless so far in multiple different chambers , aligned laser is pretty good and gets you on target immediately and then you can fine zero when you get a chance . Great price and from what I see ezshoot has been making a lot of usable budget offerings some better than others , this one has been nice for me so far

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.

Inexpensive, pretty good quality. Load in two batteries, load into the breach and sight in your firearm, easy.

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.

I needed to check my Halosun sight on my 9mm. I have found this Bore Sight Laser to be extremely accurate and speeds up the process of adjusting sights without wasting ammo.

Works great and very helpful, but refuses to eject. Dumb.

As soon as you realize what to expect and what not to expect, this little bore sight is perfect. It allows you to align your 9mm at around 10-15m to get on paper. The rest is up to red dot tuning. However, to get started and put the hole on the paper in 25-50ft away, this little sight is a must-have. It is super convenient and simple to use.

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 well. Improves aim.

I got a red dot sight and this seemed to line it up fine so far... Next test is out at the range, should be fun! The only negative thing I'd say is that the laser got stuck and I needed to pop it out, always have proper tools to help you A good cleaning kit is all you would need.

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