It was UB. I'm looking forward to your review.Yeah... DAA. I ordered one, and it could work - but you must use an allen wrench to adjust it, and if course I prefer something that uses a micrometer or index dial.
Kap or UB posted a ($85) part from UniqueTec that 'holds' the fail safe rod over enough to move the powder assembly so that a micrometer appears to clear the BF tube. Soooo... I bought one and installed it, but haven't loaded a single round with it in place yet.
