Speaking only for myself...
I might be interested in stocks, grips, and guards in colors other than black or grey, but I'm not at all interested in a one piece stock/grip combo, and I don't have any current (legal) use for short M4 type handguards or collapsible stocks.
And I don't have any real interest in pistol grips that are different than the 'standard' A2 grips.
I would very much like to see a company make a complete A2 stock, guard, and grip set that's identical in every way with the military contract A2 parts except in other colors. White, for arctic use. Olive drab. Forest green. Dead grass brown. Tree bark brown.
Fire engine red. Blue. (A red, white, and blue stock set would be very patriotic!) Purple, for hunting Barneys or Teletubbies. Pink, for the ladies who shoot. (kidding...) Camo patterns, woodland, desert, tricolor, Vietnam era Taiwanese 'purple' camo. Blaze orange for hunters. Any of the above, or all of them.
