Originality:
Transferable AR18s with original receivers, parts, and factory markings typically command higher prices due to their authenticity and appeal to collectors.
Condition:
Clean, well-maintained AR18 machine guns in excellent mechanical and cosmetic condition will sell for significantly more than worn or modified examples.
Historical Markings / Provenance:
If there are markings or provenance that link your AR18 to a specific military unit, wartime service, or historical event - collector interest and market value can greatly increase.
Restoration:
Whether your AR18 has been refinished, restored or modified will significantly affect pricing. Original finishes are typically more desirable.
Transfer Status:
Transferrable AR18s will hold a considerably higher value than their pre-86 or post-86 counterparts.

AR18s originally manufactured as select-fire rifles on factory receivers fetch higher values compared to conversions from civilian semi-auto rifles using registered sears or trigger packs.
