As some of you may know i just brought a s400f a few days ago.And the spring on the trigger at the back has came of do i need one? what does it even do? And iv notist on the old 400 they haven't got one but the new s400f has

The new AA 400/10/510 trigger units have been modified to a better spec, sideways play has been taken out, making slightly tighter assembly,

 

The trigger return spring is I believe to ensure full contact with the second pull sear because as said with no play in the working parts it is possible

 

to make the trigger unsafe. the spring is only a small one take one out of a biro type pen and install it. then remove the trigger plate on the left side

 

of the trigger. you can then cock the trigger without the gun going off and you can then see and set the trigger settings to how you want them.

i have a new spring from my shop but it keeps coming of.On the trigger there's only a little grove for the spring to fit in and it wont hold it ?

I have just looked at my own AA400F carbine and the trigger return spring sits in a predrilled cup just above the safety notice at the back of the trigger. have you got a correct length spring from your gunshop ? it has to be long enough to need compressing when fitting. if its short it will not stay in place.

not sure if its the right size but will a biro pen spring work as u said ?So when i put the new spring in do i need to do anything else to tighten it?

A biro spring is probally not long enough your best bet is to phone A A after Xmas, ask for Chris, tell him your guns trigger spring has failed

 

he will probally put one in the post FOC. phone number-01323-845853.

not sure about your problem .but you can sometimes stretch a spring a bit .so if you only need a few mm more length you may be able to stretch the spring .but you may destroy the spring to .
