There are a few, heck anyone with skills can turn a 45/70 into a BP, but I think it's pretty much old bad blood between T/C and Gonic. Custom shops will always do their thing but they aren't really "producing" barrels, and there hasn't been a Gonic BP barrel made in years but there is that patent thing. T/C got past that with the new G-2 model. Lawyers, can't do with 'em, and can't shoot 'em.
