Complete upper buying guide

An upper receiver group typically includes the barrel, handguard, upper receiver, gas system, and possibly a BCG and charging handle depending on the manufacturer. Verify the contents before purchasing. Some “complete uppers” need a BCG and charging handle to function — you need those to run the rifle.

Headspace is the critical dimension — the gap between the bolt face and the chamber when the bolt is closed. A complete upper from a reputable manufacturer has been headspace-checked at the factory. If you are assembling your own upper or combining a barrel and BCG from different sources, have it headspace-checked by a gunsmith before shooting.

Daniel Defense, BCM, and SIONICS Weapon Systems are the upper manufacturers we stock and trust for a duty or defensive application. We price match on any of these — bring us a verified competitor quote.
