As I look at Armalite's 1998/1999 catalog they list the following trigger group parts as interchangeable with the .223 M-15 version:
1) Safety Selector
3) Disconnector Spring
4) Standard Trigger
5) Trigger Spring
They list the Hammer as AR-10 specific as is, obviously, the bolt and carrier assembly. The hammer difference pretty much blows the whole deal, eh?
You might contact Armalite about some of their AR-10(T) trigger parts.
