Can be a lil annoying
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 .
