    After fitting a reg to his AA410, a pal has a severe problem. The rifle will not fire (bolt works, but no air coming through). How do we depressurise the cylinder safely to reset the reg?

    It may be a good idea to vent the gauge in the same way.

    Obviously take as many precautions as possible. High pressure air will kill you if your not super careful.

    This is why I leave this sort of thing to those,who know what they are doing.

    Undo the gauge a touch until you hear it leaking. Then leave it till it stops. And repeat.

    There may be no air in the valve and/or gauge but cylinder may be full.

    As said above the filler valve needs loosens off and the oring will bust and the air can vent off. 10mm spanner.

    As far as I understand, a regulator is installed through which no air flows and the cylinder is full.

    Yep
    It looks that way .

    So the op needs to bleed the cylinder down in order to access and adjust the reg

    Take care OP
    If in doubt maybe dyno Dave can help .
    He's up your way and very good with this stuff

    There is a small hole inside and will not allow rapid bleeding. This is a 1 turn
