Tipfun Bore Sight Kit with 32 Adapters Red/Green Laser Bore Sighter fit 0.17 to 12GA Calibers with Button Switch,Powerful Hunting Equipment,Hunting Laser Tool

Okay, so from the start i tuned several guns, irons, red dots and scopes and they were all way off and i knew it was the laser because when i turned it in the bore the laser would turn a 4" circle on my wall. I came back to this laser wondering what i needed to do to check how far it was off. I checked a few videos online and seen a neat approach with a drill. I threw the laser in my drill chuck and it drew a 15-20" circle on my wall 15ft away. So i barely loosened the 4 lock screws and i spun the drill until the laser stopped at the bottom of the circle and i adjusted the top and bottom screw until i pulled the laser more towards the center of the circle. I kept doing this until the dot stayed in one spot and now the laser is accurate enough to get my optics in the ballpark. Follow this review and get your laser adjusted correctly, easily and you are good to go!

With the multiple tips, this gun device fits a variety of gun barrels saving you from having to buy multiple devices. I've used it to help sight 3 guns and it's proven to be a game-changer - it confirmed what I thought, the iron sights were a bit off. Using this device allowed me to adjust the sights to improve my marksmanship.

Fits any barrel with the adapters. Easy to use for setting sights. Green laser is well seen during the day. Used it for open sights and scopes. Reduced the amount of shooting needed to sight them in. Only issue I had were the small adapters for smaller calibers that I was afraid of dropping and losing. Other than that it worked great!

Excellent and VERY bright!

works pretty good. Hope I dont forget it in the barrel again like I did the last one lol. I also used this on my crossbow I just laid it on the bolt rail

No so accurate laser not center’d at all

Nice bore sight kit. Green laser is very bright to sight your gun indoors or outdoors. Comes with a plethora of barrel arbors to securely seat the laser sight, 2 batteries, screwdriver and large bore cone. The arbors are numbered (in millimeters?) so you just have to pick one that will fit your barrel. Trial and error style. It will get you on paper. Then fine tune your sight after. Overall very pleased with this product

Great investment if you have a collection of different weapons that need to be dialed in. Not only that but it comes in a nice hard case to keep it organized and there’s directions for any questions
