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

This works great for me in setting up red dot sights on 9mm pistols. It gets me within a 4 in circle at 15 yards and then I can dial it in on my own. It is not designed to be dead on at 25 yds. Rather it gets you very close so that in 2 or 3 shots you have it dialed in.

Very easy to use. Very bright and sharp. Very accurate and well designed. Good value.

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.

it works like advertised the adjustment ability with out having to go to the range to zero out you laser or red dot is key, when i wnet to the range it was zero was acurrate, the aligment was spot on and the distance and visibility and brightness to accurately zero in daylight is great! make sure to push it in the barrel so it can be snug and acurrate!

The laser is bright. But you need to wait til dusk to see it enough for an accurate zeroing. It fits perfect in my AR and since the laser goes through the barrel and puts a dot exactly where the bullet would be, its accurate.

This worked very well lining up my red dot. Worth the money!

As described and functionally accurate.

Seemed to be the ticket but, once on the range different story. Red dot was way off.
