Not a writer, but I have and have had enough custom rifles to appreciate the difference.

Along about mid eighties, I bought an early commercial FN barreled action and since I had kids in college, opted to go with a Brown Kevlar stock. I had a smith bed, finish and paint it. Basically, this was a bolt together job. Not a custom build. A friend still has that one. I replaced it with a custom stocked version. Still have that one.

As I recall, the choices were limited, but synthetic stocks had been out for a while.

Best,

Jack
