I got each RBL as they came available and have had no issues with any of them. The original RBL-12 I got was exactly what I had ordered but when I got it it was just too heavy and the handling wasn't to my liking. So, I took it with me to The Vintage Cup and spoke with Lou about it. He said to leave it with him and he would see what he could do. Said it might take a while. A few months later I got a phone call while on my way to shoot sporting clays from a lady at CSMC that a package was on its way to the FFL on file with my account. A few days later I had one of the light weight RBL-12s built on the RBL-16 frame.
