  • Tim from USA asked:

    Will this fit the older Sam Yang 909s light hunter (single tank)? If not, where can I get one for that gun? Better yet, where can I get the correct orings for it?

    • Mark from USA:

      The tank plug will not fit the older 909. For an o-ring set contact Saddle Mountain Gunsmith.

  • Mike from USA asked:

    Is this the check valve that keeps charged air in the cylinder? Will this fir the Seneca 50 Caliber Wingshot II? If not, does anyone know correct part number and availability or repair parts? My gun charges fully but discharges all the way when bleeding down to disconnect pump.

    • John from USA asked:

      Is the Eun Jin check valve assembly SKU: Seneca Tank Plug... the same as the replacement check valve SKU: Eun Jin Replacement Check Valve...?
