I think McMillan will essentially make it any way you want if you don't mind the wait.
I got my A-5 used, inlet for my action but for RH. I'm a lefty, I hogged out a bolt slot on the left side and filed down for the bolt release, then filled the old cut-outs with marine-tex; sanded down the channel and bolted my free-floating barreled action into place. Dropped right in and fit like a glove. Once the scope comes in I'll be duracoating the whole thing, I expect the stock will take the paint quite well.
