You can add all this to your Stag for another $100, if it is important to you.
Honestly, if I was spending that money and could find one in stock, I would buy the Colt too. You can get that rail handguard from Stag and replace the handguards on the Colt and still be ahead.
Replacing the barrel and BCG will cost a LOT more than $100 to match the quality of a BCM, Colt, LMT, etc...
