Or you could take out the anti tamper and do the job properly yourself. In a day. Sod the warranty if it takes 4 weeks.

Just my opinion

And mine also, your a man after my own heart Peter

That's all very well if it's a simple venturi adjustment. There's not much to go wrong with the unregulated guns but if, for example, you needed a new block it would be a costly mistake.

Cheap as chips from Julian. The stock is the most expensive part (and I threw mine out as it was total pants)

To be honest the power adjust cover screw is the only one I use a pillar drill for, the other three I do by hand with a battery drill, but I have done quite a few, including my new to me TDR

I wish they wouldn’t use such hard stainless for the cover screw.
I started mine off with a hand drill and cobalt steel bit and got probably 1mm deep but it was so hard I had to transfer to a pillar drill to get the pressure (not in the video!) Only had the one 2mm bit and didn’t want to twang it.
Its a beggar to hold it flat on the drill table.
How do AA approved service centres get them out?

Don't know how the service centre does it, my pillar drill has a small vice fitting which keeps it still, and I use a centre dill, not an ordinary 2mm wobbly bit

Although I've taken out several venturi AT's successfully, after a recent incident involving a broken drill, a lot of swearing and a lot of damage (fortunately to my own rifle otherwise it would have been very embarrassing ) I will just buy a new firing valve body. Call me a coward, but....

A couple of months ago there was a jig for sale on e-bay purporting to be as used by AA to drill out the power adjuster cover screw. It was a semicircular collar with a hole that lined up with the cover plug.
It went for £40 ! I've tried to put up a picture of it without success.

You don't really have to drill them out, just into the cap, then tap the end of an Alan key into it and unscrew

It's on my list of things to do, drill a hole in it as per TenmetrePeter's Youtube video and tap a torx bit into it for ease of turning.

Absolutely! 2mm dia by 2mm deep is plenty.

As the plug is conical I expect turning up a sleeve with a 2mm bore and female cone would be easy. A centre punch is a lot quicker and you have to remove the pip either way.
