303 British Laser Bore Sighter to 12 gauge adaptor by williamdeer

Adaptor to allow a bore alignment laser for a 0.303 British calibre to be used in a standard 12 gauge chamber. Why buy 2 bore lasers when you can use the same one for 2 firearms... Being able to sight in or test technique without using real ammunition is a big plus. NOTE: Do not use with live ammo... That would be unwise and potentially fatal.
