Not what Harriman told me once your 8 weeks is up or prior to that once your licence expired you are breaking the law. I had staffs keep telling me I was ok as had filled forms in but a phone call to basc it was not trueThis is not true.
Your local firearms team are responsible as long as you have had your renewal apica toon in for eight weeks prior to expiry.
They simply update the relevant database. Been there done that.
