W&s steel trigger ghk ak

[John boy]

Hi everyone 

I am fairly new to airsoft so I have likelyade a mistake.

 

I installed the W&S one piece trigger set into may ghk ak74 , I have the w&s steel hammer installed too but the sear is the original ghk one.

 

So now the ak only shoots full auto and not single shot so not sure what I have done wrong.

Sorted it now, I fight it attach the sear spring that was attached to the old trigger
