This AR18S made by sterling for Armalite Costa mesa.  This and a AR180 were the first two sterling guns into USA.  Difference from an American AR18S:

  1. Serial number is AS033 – their meaning Automatic Shorty…033rd gun made, not 33rd Shorty.  The only gun in USA with that type serial number.  A=Auto,  S= semi and this one.
  2. Top receiver stamped AR18S , not like the American AR18S where nothing to mean a shorty.
  3. the barrel is about an 1 inch longer
  4. different style flash hider
  5. Flash hider has a front sling rotating clip
  6. Op rod has a sling clip on it.
  7. straight pull charging handle
  8. the Front pistol grip has a different style screw in block.
  9. A tad different, front hand guard cap
