Wheeler just makes great product. - Wheeler Professional Laser Bore Sighter

During this time where Ammo comes at a premium cost it’s nice to be able to get your scope on paper before ever firing a shot. It’s not going to be a perfect zero but it’ll be close enough to only need to fire a few rounds to zero it in.
Directions were also clear and easy to follow. The only thing I would suggest is removing any muzzle device before using to ensure the laser is in perfect alignment with the barrel. The previous advise is not a requirement in the directions but I’ve found it works the best this way. Oh and make sure that the end of your barrel is clean of all metal shards that could attach to the strong magnet on the Laser bore sighter that might interfere with a perfect attachment to said barrel.
Long story short I’ve tried a multitude of different laser sight in tools and this is my favorite due to it not having to be pushed into the barrel at either end where there’s a chance of damage to the barrel rifling.
