Prohibited Bore / Section 5 Weapon

Definition

In India, a 'prohibited bore' is a firearm above 0.32 calibre or a revolver above 0.455 calibre, defined in the Arms Rules. In UK law, section 5 of the Firearms Act 1968 lists weapons (automatic weapons, certain pistols, short-barrelled guns) whose possession is an absolute offence without specific authority. Classification into these categories carries heavier penalties.

Common questions

How does the UK's section 5 differ from ordinary firearms certificate offences?+

Most firearms in the UK are held lawfully under a firearms or shotgun certificate issued by the police, but section 5 weapons cannot be certificated by ordinary means, possession requires specific Home Office authority, so holding a valid certificate for other firearms does not extend to a section 5 item.

Why is the calibre threshold significant when classifying a seized firearm in India?+

Whether a weapon falls above or below the 0.32 calibre threshold, or 0.455 for revolvers, determines which licensing category and penalty provisions apply, so accurate calibre measurement by the examining laboratory can directly affect the severity of the charge brought.
