Reply #45: My M-16 (when I was in the Army) had the Auto selector permanently install [View All]

And the M-16 trigger housing had no affect on its action (Automatic or Semi-automatic). Now the older M14 was designed to have a removable automatic selector switch (The M14's safety switch was separate from its Selector switch). Most units keep the Selector Switches off the weapon for the 7.62mm Round in a M14 was to powerful for effective automatic fire (For most people in most situations, the M14 was to light a weapon for the 7.62mm round in Automatic fire).

Unlike the M14, the M16's selector switch and safety was one and the same. You switch it from Safe, to Semi to Full as needed. The M16 could NOT be made semi-auto only just by removing its selector switch for it required the complete rebuild of the Trigger and safety groups (and the M16 was NOT even design for CLEANING in that area let alone such replacement of parts).

My point here is are you sure it was a M16? Sounds more like the M14 and its removal selector switch (Which was NOT part of the M14's safety).
