Almost but not quite there - BSA Optics Laser Bore Sighter Kit with Shotgun Arbors

have used mine for eight years now on many occasions and wish i had never purchased it.the spuds are too undersized in the bore to do any good. pretty much makes this unit useless. the collumater however is way better and i like the case.the only fix i can see is to find and acqire an adjustable spud that will expand the spuds to the needed diameter to stay in line with the bore.
