Choosing the Right AR-15 Upper Receiver

The right AR-15 upper receiver depends on how you plan to build and configure your rifle. Stripped uppers offer maximum flexibility for custom builds, while assembled uppers simplify the process by including forward assist and dust cover components.

When selecting an upper, prioritize proper machining, mil-spec compatibility, and handguard mounting alignment to ensure smooth assembly and reliable long-term performance.
