I have to give a shout out to TNVC since they are a site sponsor here. I have one of their TRB battery systems for my Trijicon and over tightened the rail mount to where the mount bracket split. Called and requested the replacement part and told them I'd pay for another as it was my fault. Cannot recall who I spoke with there, but he told me no problem, it happens and he'd send me another at no charge. Wouldn't even let me pay shipping. I was expecting just the part, but when it arrived today I found they had replaced the entire unit. This is what CS is all about, thanks guys!
