Scope Boresighter Kit from .177 to .50 Caliber Precision Firearm Bore Sighting Optical Bore Sighter Kit with Arbors

Works great, had my scope sighted in less than 5 minutes!!

It’s a close copy of the old tasco boresighter , it uses round (approx. .030“) spring stock in each rod to hold it in alignment w/in the bore and in some of my rifles when the grid is centered this same spring will be on the the edge of the rifling land and will “trip” off the land’ edge and spoil the alignment if bumped or sometime’s on its’s own , Hence the annoyance. It’s workable just annoying . The old tasco & bushnell’s had expandable guide rods that locked in place providing a sturdier foundation. BUT those are hard to find for a fair price ! So the annoyance can be lived with and a lil tinkering could solve it. All in all it is a good investment .

Excelente colimador optico de buena calidad y multiples funciones para diversos calibres; buena relación costo - calidad !!!

Good product just didn’t work for me

As expected

Not of the best quality but works well. My son was very impressed in the difference it made in his shooting.

the spring mechanism on the barrel arbors do NOT function properly. They won't go in like the are supposed to.

Great buy
