I see mac-11 uppers for sale at:

Aves
Parts Dispensed
JC Arms
MasterPiece Arms

Since MPA only has the side charging upper immediately available, can I purchase a side charging bolt from another vendor ? I'm guessing MAC-11 is a specification as well, so parts should be interchangeable.
If not, whats the opinion of the complete uppers from Aves ?
