Nelahol Bore Sight Cal .223 Rem Boresighter 5.56 Boresight 223 5.56x45 mm NATO Laser Bore Sight with 3 Sets Upgraded Batteries

Good little bore laser, sits zero at around 50 yards with iron sights. Would recommend if you are on a budget.

Not bad for it's price.

Complete waste of money. These things are always a gamble but man this is not good.

Already had an Osprey brand .223 laser bore sight. But after sighting with it twice and missing shots I suspected the laser in my old one was off.This one comes with a nice small case easy to take in the field. Batteries are stacked which is really nice because they can be small to handle. After installing the battery I signthed my scope while on a bi-pod and rest. The dot is a bit diffuse at just fifty feet. It's more diffuse than my old one. Also also more.diffuse from an even older (different caliber) green laser bore sight I have.But with that said I just adjusteded the reticles to center of the large laser dot projected at about 50-55'. Out past that distance the light was too dim to see in day time. So you might have to sight at night or on a dark cloudy day. In sunlight I couldn't see the laser dot past that far.

I have recently got into hunting and my husband advised I needed to sight in a rifle that I bought recently. This Boresight works exactly as I needed it to and really helped me get everything lined up and good to go. I'm satisfied overall with it and am glad to have it on hand for future use as well.

I love the way the batteries were upgraded. They somehow taped together so that you can put all three in the boresight at once and remove them the same way. You must remove them when not in use as there is no switch. This perfect little boresight fits directly into the chamber and easy to remove.This is a good quality item that is valuable to have on hand for targeting. The case opens and snaps shut tightly and is exactly like the company picture in this listing. 5-star item!

My review that I already got confirmation about says it all. This is recommended at this price. It does what it should.

I could not get this to work. Followed instructions loaded into an Adams Arms 15. Never could get the beam to come on and it got stuck. Used a military method of bumping the stock to get it out. Not even thinking about trying again. Could be user error. Could be a bad casing (swelled). I don’t know. I just know, that this reviewer, loaded the laser sight cartridge into an “AR15“ and it got stuck.
