No, the 1895 receivers weren't all carbines.  There were the Model 1896 Cadet rifles, 404 of them.   The majority were 1895 receivers.  I think 4 of them were museum examples made on Model 1896 receivers.  There were also some, but not many, regular infantry rifles with 1895 receivers.  I can't recall the particular serial # range we decided was right for the those cadet rifles, so I'll let someone else fill that in, but I think you might be in there!  Those Cadet rifles were returned to the arsenal and converted to service rifles by adding sling swivels, filling the cleaning rod channel, filling the band spring slot, (Said filler might still be visible on your friends carbine, if it made it back into a modified cadet stock),  drilling holes for the butt trap,    Sometimes they got back in their thin wrist stocks, sometimes they wound up in thicker wrist 1896 stocks.  A cadet rifle should have an 1895 cartouche.  Lots of famous military minds at West Point during the short service life the 96 Cadet rifles had, chief among them, Douglas MacArthur.
