Dave is a class act
I remember when he sent out the first NFPJ conversions. He wasn't 100% happy with them and sent everyone that bought them a improved version. Mine wasnt bad at all and i told him that. He told everyone to keep the first one too.
I lost one of the FPJ bolt adapters once and when i ordered some other stuff i asked if i could just buy the adapter too. He sent me one no charge.
