Tests by the NCA revealed that the firearms can be easily converted into lethal weapons, making them illegal to possess under the law. "Surrendering these weapons now will help prevent them getting into the wrong hands in the future and being used by criminals, so we want as many top-venting blank firers as possible to be handed in." Top- and side-venting blank firers are otherwise legal in the UK for those aged over 18 unless deemed readily convertible. However, the following BRUNI models have now been categorised as illegal:8mm PAK Bruni BBM Model 928mm PAK Bruni BBM New Police8mm PAK Bruni BBM Model 968mm PAK Bruni BBM Model ‘GAP’.380R (9mmK) PAK Bruni BBM ME RangerIndividuals are being encouraged to surrender these firearms at police stations in Carmarthenshire (Ammanford, Carmarthen and Llanelli), Pembrokeshire (Haverfordwest), Ceredigion (Aberystwyth and Cardigan), and Powys (Brecon, Llandrindod Wells and Newtown). Those handing in TVBFs during the amnesty will not face prosecution and may remain anonymous.
