AR15 Complete Upper Receivers:
Below you will find a general reference of the types and styles of complete uppers available from various manufacturers. When choosing an upper keep in mind that the prices vary quite a bit. In most cases the more expensive units have better barrels and or handguard's. Also be careful you don't violate local laws with your selection of uppers. Lastly there is a shortage of all things AR15 and regardless of where you order your upper your going to most likely wait a year or more. I suggest just get a few on order with your suppliers of choice and be surprised when UPS drops them off in 18 months.
