Massachusetts Rifle Team semi-auto M14s
Good friend in Massachusetts with his son are on the state rifle team. Until a few years back, they were equipped with Army owned M14 rifles on loan. The selector switch had been removed, leaving the shaft with the rifles locked into semi-auto only mode. Recall sitting at their kitchen table having coffee while examining one of those M14 rifles. That particular piece was of TRW manufacture. Was told that at least one other M14 in possession of the rifle team members, was in fact built by Harrington & Richardson.
Since then, those M14 rifles have been returned to the military for service use. The target shooting team now uses AR-15 match rifles.
