Williams Gun Sight is a great place. They devolped and manufacture a lot of sights that otherwise might not be available for many guns. Customer service is excellent, well stocked, and knowledgable staff. On 2 occasions their gunsmith did a great job for me, on a Baretta shotgun and a Browning A-bolt. They always had the BP stuff I need, and the shooting range very adequate. One of the places I miss since moving out of Michigan. I was a 100 mile round trip for me then, but worth the drive. Cabela's was 160 round trip and not as beneficial as going to Williams.
