I don't think so, Gnoman; not exactly anyway. While the process is the same, the term "monobloc" would mean a single forging comprising the chamber areas for both barrels (as well as the lumps) into which the two barrels are attached, while most sleeved barrels would involve chopper lump or other froms of original barrel maunfacture which are cut off just past the chambers and the replacement barrels attached...Geo
