AR-15 5.56 NATO Lefty

Shop 5.56 / .223 left-handed AR-15 uppers from Moriarti for shooters who prefer a true left-ejecting configuration. Browse left-hand upper assemblies in multiple barrel lengths, handguard styles and finishes for 5.56 NATO and compatible .223 configurations. Unlike a standard right-ejecting upper, these left-handed AR-15 uppers use a dedicated left-side ejection setup. Check each listing for chamber specification, BCG, charging handle and included components.

Can a left-handed 5.56 upper be used on a standard AR-15 lower?

A compatible left-handed 5.56 AR-15 upper can generally be paired with a standard-pattern AR-15 lower receiver. The left-handed configuration is primarily in the upper receiver and its corresponding left-hand ejection components. Always verify the individual upper's specifications and component compatibility before use.
