I don't know if it is possible at this time, but, Browning used to sell the
"Stalker" composite stocks, which, could be fitted to an older A5, and didn't crack. Either the store bought version of the "Stalker" or an older A5 with the new stock and a Hasting's barrel, are a pretty decent do it all gun for a guy who only has one.
I have my Dad's A5 that he bought new, when he made Sergeant in the USMC in 1952, fitted with one of the plastic stocks, and a lefty safety. Dad had a variety of Hasting's barrels and the original solid rib barrel. The original wood is here, someplace, but it is pretty beat up and has about a 12 3/4" LOP. I don't think the gun is actually worth all that much, but, I wouldn't take $10,000 for it.
He hunted pheasants and later, ducks and geese with it, all of my life.
Best,
Ted
