I want to switch the 1:12 .223 barrel I have for a 1:9.
The barrel I have has no markings or serial number on it. If that barrel is irretrievably destroyed (angle grinder to the chamber, cut up etc) before I chamber its replacement then has the law been broken? Home office guidance is clear about component parts (you would need a variation to acquire a chambered barrel before switching), however if an RFD undertake this then no variation is required. Presumably this covers the situation where 2 chambered barrels exist (the RFD having requisite authority to possess).
Its no great problem either way, I can put in for a variation. On the other hand, there is no point at which I have acquired or am in possession of a firearm or component parts that I don't have the right to hold (given that the right relates to the complete firearm).
I'm sure this has been asked before, couldn't find a definitive answer though.
