Don't badmouth the humbler, boxlock AYA shotguns. About 30 years ago I found a well – used AYA XXV/BL at a second hand guns rack. A boxlock ejector in 12 – 70/2 ľ". Special order 27" chopper lump barrels with Churchill rib, bored improved/modified. Weight 2.9 kg / 6.4 lbs. The action is still tight as a bank vault.

I had to lengthen and refinish the cut off buttstock again. It's been my favorite shotgun ever since. Perfectly balanced, better than any sidelock (have a Purdey too) or over-under I have ever handled. I simply look at a bird or clay, the gun hits my shoulder and goes bang. Most of the time the bird comes down. (yes, I can miss with any gun). It's simply the perfect using shotgun for me.
IIRC I then paid DMark 360.- , about Euro 180.- or US$ 200.-, for the gun. That's about 5% of the 2009 AYA factory list price of Euro 4460.- incl. VAT.
