If I buy a barrel and bolt combo and upgrade to a forward assist adapter, will the bolt have all the Evolution features (live round extraction, cotter pin firing pin retainer, firing pin / cleaining rod combo, etc...)? Not that this would stop me from buying your product, but I might have to buy just a complete upper first, and then latter buy the barrel for another build
