In addition to my old favorite, Seneca Arms, I stop in as often as I can at Ackermanville Gun Shop, about 2 miles south of Bangor, PA. I've known Brian for many, many years- he's a good guy to deal with, we did a nice deal. His phone is 610-588-3567 or email him at abrasives@enter.net. He's just starting out but he's getting busier by the minute...if it isn't in the shop he'll get it for you.
