A friend of mine bought a new gun which was way over the limit , he sent it back and had to wait six weeks to get it back !
We took it out for a test and believe it or not it was over again - by this time he was thoroughly fed up with the gun so had the AT removed by a clever bloke he knows
I think its absurb that guns can still leave the factory over the limit , the problem with AT is that its not being backed up by the manufacturers which leads to dissatisfied customers waiting to have new guns de - tuned .
I would not buy an AT gun , I recently did a lot of work on my guns and one was just over on some shots so a quick tweak put it back under again .
The problem here ( as rightly pointed out by a Mr Doe ) is that if you can turn it down you can also turn it up . Thats the sad truth .
