## Description

desertcart.com : CVLIFE 12 Gauge Bore Sight Laser Red Dot Laser Bore Sighter with 3 Batteries : Sports & Outdoors

Review: Awesome and easy to use bore sight laser - This works great. Good price, battery life is great, the laser is bright and easy to see. It fits perfectly in my 5.56 rifle. I couldn't ask for a better sight laser. It gets it as close as possible without putting rounds down range.
Review: Economical, Easy to Use, Bright Laser 223/5.56 - I needed a quick, easy, and budget option to set up iron sights on my first 5.56 AR and this CVLife Bore Sight Laser for 223(5.56) did the job very well. It's still essential to go to a range and dial in a zero at proper distance with live rounds, but this will get you on paper and save range time and ammo. The package includes a laser cartridge in 223(5.56) and six batteries. The cartridge takes 3 stacked batteries at once, and each set of 3 batteries lasts approximately one hour, so 2 hours of total use from included batteries. Function: Simply unscrew the endcap from the cartridge, insert 3 batteries, screw the endcap back on, and your laser is on. Once the laser is functioning, you simply place the cartridge into the receiver and *gently* ease the bolt forward until the cartridge is fully seated. You don't want the bolt slamming the laser cartridge into battery as you would a live round. Your chamber may not fully close, but that's ok as the cartridge simply needs to be held in place by the bolt and centered in the bore. You now have a red laser dot shining out of your barrel to which you can sync your iron sights or red dot. I only have about 20 feet of "targeting" distance in my home, so I was mainly concerned with getting the windage adjusted on my iron sights as accurate elevation would be near impossible at this close range. But now I can go to the range with a little more confidence in my initial accuracy and begin the real work. Verdict: Since you'll need to go to the range anyway, this laser cartridge offers an easy starting point for zeroing your sights at a budget price. Checking the alignment of sights between range visits is also a viable use option, but this functionality would be improved with the addition of an on/off switch as removing and installing the batteries for each use is a little cumbersome. At 20 feet the laser is very bright, but somewhat "fuzzy", so I'm unsure how accurate this would be over longer distances. Overall I am very happy with this as it does the job advertised, just be advised that it is only the beginning of the zeroing process. I expect to use this often.

## Questions & Answers

**Q: How do i know lazer is center?**
A: Lay a magazine down flat on a table and place the laser in the magazine side groove. Point the laser at the wall, ideally 25m away but as far as the room allows. Rotate the laser in the magazine groove while observing the point on the wall. If the point remains constant the laser is center.

**Q: Do you close the bolt on this to secure it in the barrel when sighting?**
A: Yes, but close it gently so that the sight is securely in place.

**Q: Can this laser aim point be adjusted or calibrated?**
A: Yes, it can. It has adjustment screws. You will need a lathe or floor drill press with a straight quill. Turn it on and clamp it in the chuck, then slowly by hand, rotate the chuck. If it is aligned correctly, the laser point will not move. If it goes in a circle, it is not aligned. Adjust the setscrews until the laser dot does not move when the chuck is rotated.

Do NOT turn the drill or lathe on! The further away you can set the laser dot, the more accurately you can align it. You cannot align it while it is in your firearm.

**Q: Why does it say “9mm rem gauge” ?? Is it for 9mm caliber pistols or for a shotgun?**
A: It is for 9mm Parabellum ( 9x19mm). Works great.
