BoreSighter for 223/9MM/7.62X39MM/30-30/30-06/.25/270/243/308/7MM/ 45ACP Colt Caliber Rifle Scope Handgun Brass Red Dot Boresight Kit for Hunting with AG3 Batteries (Special, Bullet Type)

Works really well. I prefer these to the laser kits with the screw on tips, the kits tends to bend coming out of some of my rifles but these are snug in the chamber. Laser is bright and easy to see.

Comes in tactical case. All sights fits. And very strong lazers. Very pleased with their product.

Overall good. Fit snug in my g19x and my geissele urgi perfectly. Aligning my optics were straight foward. I do wish the laser was brighter because it cannot be seen during the day with the batteries provided fresh out the box.

This laser boresighter worked exactly as advertised and was a great tool for the job. It came with multiple caliber options, making it extremely versatile. I used the .45 ACP boresighter to sight in a .460 S&W, and it worked perfectly. The build quality is solid, and the laser is bright and precise. Highly recommend for anyone looking to quickly and accurately boresight their firearms!

these are probably okay for some, but i couldnt get mine properly lined up. i have others so i know i was using them right. woudlnt buy again!update: they made it right. followed up consistently. fixed my overall issue. i recommend the company. 5 stars for taking care of the company.

Used it to bore sight my Glock.Will be buying for 308

I like that it was cheap. However, you get what you pay for. The casing on this 9mm laser bore sighting tool is not designed well. The casing is tapered smaller at the laser end and larger at the “primer” end. The only part that seems to make contact with the bore is the very last bit of the primer end and it feels like maybe it’s a few thousandths too small even when fully inserted. I put this tool in an already well sighted (manually sighted at the range) that was known to be accurate and the laser indicated that I was high. I rotated the pistol upside down and now the laser is showing the opposite. The laser was always on the bottom of the circle reticle (507k green dot) meaning it was loose enough in the bore to be hanging down if you will. At any angle the laser was always showing low in my reticle circle. Quite low. Physically on the wall at 21’ it was about 1.5” low no matter what orientation my pistol was in. !!! Not good. Going to return this.

Easy to use. The .223/5.56 was spot on and enabled me to get accurate hits. The 9mm did not work in either a pistol or AR9. Sights were very off to the right of impact points on both leading me to believe the boresight is off or I got a bad unit.
