ARRSE is a UK based website and as such no firearm can be listed on this board. Firearms include all component parts of a firearm, sporting, collectible, curio & relic, signalling pistols, and antique firearms, regardless of their capability to fire a shot. Any item that is designed to discharge any shot, bullet or other missile is covered by this ban, regardless of that item's present ability to fire. Replica or imitation firearms are also prohibited. Weapons which discharge noxious substances, liquids or gas, including tear gas or pepper spray dispensers, are also prohibited in the UK and on ARRSE.
