I do a lot of work on composite/fiberglass stocks.
I've converted HS Det Mag stocks to BDl and ADL.
I've converted left hand to right hand, done adjustable combs and repaired KS stock that someone tried to make into a BDL, returning it back to ADL.
I'm working on converting a Beretta Mato to fit a Rem 700 ADL long action.
Good thing about fiberglass is, if you don't like it, grind it out and do it over.
Here are a few pictures
