    Hi everyone

    Is there someone who can tell me how to open up a BSA airsporter stutzen so that I can replace the main spring and seals..... the trigger housing is cast alluminium and is somehow connected to the rest of the gun, I cant tell if it is screwed on or push-and-twist. I am more curious how BSA made these guns than to attemped to dismantle the gun personaly but I would still like to know


    Thankyou for looking

    David

    It should unscrew mate. Is there a hole in the trigger unit? About three eighths of an inch? If I remember rightly, you put a bar through this as a lever to get it started. BUT! Anything can happen when it comes free! Depends on the spring pressure.

    Thankyou Mick Dundee

    Yes there is a hole in the trigger unit, And I find it interesting that it is screwed on instead of being held in place with a pin....... Ill take your warning and allow a gunsmith to replace the mainspring and seals, at least it will be chronoed to 12ftlb or under

    Many thanks David

    Hi there david, i live not far from you and own a similar bsa gun, the chap who owns the wiltshire shooting centre in devizes told me to put a bar through the hole by the trigger and put the gun in a vice, then twist. My piston spring is stuck in the cocked position and i'm too scared to undo it! I'm after any advise anyone has regarding my issue.
