I see mac-11 uppers for sale at:

  1. Aves
  2. Parts Dispensed
  3. JC Arms
  4. 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 ?

    Idk for sure with mpa but I bought a MAF upper and bolt and a year later aves had a sale on their mac bolt so I bought one of theirs. the MAF upper works fine with both of them. I would assume the same is true for all of them but I wouldn’t put it past any company to make their shit proprietary if they knew they could.
