Narrative:

PA32-300 depart from pgsn with 2 passenger at XA55 for pgwt. Flight after 1 min passing reporting point and joining left base for wy 8 pgwt at approximately XB02, I reported left base for runway 8 pgwt. Approximately 1 min after flight beginning to turn final runway 8, 2 military helicopters suddenly reported right base runway 8. At that time the helicopter is turing final in front of me. Approximately 1 - 1 1/2 mi between my aircraft and helicopter about the same level at 700 ft, flight executes missed approach immediately proceeding right side upwind and cross overhead runway and rejoins left downwind for runway 8 to avoid that traffic. After the flight landed pgwt at XB05, I checked with FSS regarding the helicopter reporting status. FSS replied that the helicopter only reported right base runway 8 then landed on pgwt and no further report.
