Indeed. There are two 6mmARs in my AR15 safe because I bought two MBT-2s when they went "on sale briefly" several years ago---having no intent to build a rifle at the time. I have a pile of AR parts tempting me right this minute, one being the spare Geiselle. I think I'd best move that stuff before a pile of parts for a .375 or .458 SOCOM parts appear on my bench.
