I think coming out with yet another different length of handguards would be a bad idea. Offering uppers with the Armalite/RRA mid-length HGs and a slightly longer barrel so the FS fits in the right place I think would sell. "New for 2005: Bayonet-length uppers in post-sunset configuration. 16.xx" barrel with mid-length handguards. Fits standard __ bayonet and comes with your choice of Phantom or Vortex flash suppressor."
Mike_L: I agree with you, this would be the best way to go, the slight increase in barrel length would be a plus in my book. I really have no use for a bayonet myself it is just the idea that one could be mounted correctly if need be.
