There was a source where people were getting their sight blocks from but it was a special case. IIRC, the guy worked for KAC and would install them as well. He was on ARF so that's where many of them got them. I believe he left KAC and so the availability dropped to zero. The problem with the gas block sight base is that KAC required it to be installed by them. At least that's what I've read.
