Quoted: Which is correct for a 13,XXX serial (1968) AR-15 rifle, 3 prong or cage? Seems the 3 prong is correct according to the data but you never see any installed. Did these get changed out over the years due to the cage being a better mousetrap?
Thanks for the help.

According to the AR15 SP1 Database... 162XX Birdcage, Plain hard rubber (?) buttplate W/drain hole top screw, black carrier "C" stamped, + on lower, ,notches in the black carrier, C MP C ubarrel, bobbed disconnector, roll pinned swivels, rubberized and black nylon sling, Came with spare Edgewater buffer & spring
1970
15271 three prong, no hole in selector, no pin on, swivel, pin on front swivel. C MP C
1969
14418 solid buttplate 1969 Three prong
14300 barrel marked c2 12, "polished" FSB, duck bill, roll pin on swivel, + on lower, made in 1969
13192 three prong, no trap door, pinned on front swivel, no roll pin for receiver extention,
13XXX duck bill
1968
12760 three prong, + on lower, MP by FSB, 12 near muzzle, roll pinned front swivel, receiver extention not pinned in, no trap doorThat information would lead me to believe that either the three prong or duckbill would be correct for that serial number range. Still, to answer your question, the flash hider could have been changed out for a cage as civilian rifles were often upgraded as parts availability allowed.
