I have owned several SXS AYAs, mostly sidelocks but a few boxlocks. At least half of them didn't shoot together. I have a No 4 that placed the barrels' point of impact 10" apart at 25 yards. I couldn't figure why I missed with the back trigger until I patterned it. I've also had a few with broken parts, particularly springs. That's why used AYAs bring about 50% of their new cost. I had a plain Ugartachea 20GA that never missed a lick and brought down birds at very long ranges with IC chokes. I don't own any Spanish guns now.
