the AR-15 cn do it all like josh said....there was an article in shotgun news last month or the month before about it....everything from tactical machines to the finest long range rifles out there....holding groups tighter than most bolt guns...my dad got into building them.....instead of swithing everything on the same lower he just decided hey since i made my gun a shortie i will make this on a full size...and just keeps going....would be cheaper to switch but alot easier to just pull a gun out of a case and shoot...i dont think id like wood on an AR...just wouldnt seem right to me...ive seen some really neat paint jobs and some of the dipping places could make one look pretty nice...but wood on an AR just doesnt seem right to me....i can bet someone makes them though....just seems like someone would thought of it already........
