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.

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!

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.

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.

Excellent fit easy to work with the brightness was perfect made everything so much easier

This things is pretty nifty, and actually got me a lot closer to zero than I expected. Maybe a hair of adjustment was needed for a 15 yard zero, but it’s worked well on my P365 with a Romeo x compact optic. I do have to make sure it is very well seated in the chamber, and I often have to push something down the barrel to extract it (not too difficult, I use a plastic paint brush handle), but it has been otherwise pretty good for me.

Distances below 30-40 yards you can pretty much skip going to range using this. Past that it'll still help get any pistol/carbine pretty close to zeroed and save you some ammo. I used this with a cheap reflex sight and got good results. Can still see the laser in a fully lit room/hallway, but I wouldn't bother in broad daylight.

The EZ boresight operates as advertised. I have used it three times, trying to zero my red dot optic. Two out of three times, the laser boresight would not eject from the chamber. I had to disassemble the entire pistol and then yank or pry the device out of the bore! I suppose that there is an advantage to this, which is that the zeroing may be more accurate because the device cannot wobble around in the barrel. Unfortunately, it's also hard to remove when you're done. On the positive side, I am getting to be quite an expert at disassembling and reassembling my P365.There was a little readjustment required after the initial zeroing attempt, but not bad.
