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 ?

    all good to know… ill be back in touch once i start the build. eta 1-1.5wks just wanted to get some feedback first before deciding if the build is currently worth it or not… in the sense of not too many tweaks are needed to get the thing to work.

    i already have two unseen builds complete in the past 7 days…

    1. r3
    2. r45

    so anything he releases im on it…

    thanks!
