I'm not sure why AT was introduced
I remember reading on the BBS that it was a joint decision taken by the trade association in the UK, but I can't remember what the reason was and if you even mention it on the BBS you risk being banned.
Is it something to do with 'capable' rather than actually being over the limit?
What I mean by that is that if it leaves the factory sub 12fpe with AT fitted then it isn't 'capable' of exceeding 12fpe
Dunno, and don't really care tbh - I'd just have the AT removed anyway.
I don't see what the problem is with telling someone how to remove it themselves either, it's not a legal requirement to have it fitted and there are plenty of threads all over the forums on how to undo a few bolts and swap out a spring on a springer (which could quite possibly put the gun over the limit) so what's the difference?
