AERO AR15 COMPLETE UPPER 10.5 5.56 CARBINE BRL

The Aero AR15 Complete Upper 10.5 5.56 Carbine is a ready-to-run upper receiver assembly built for short-barreled rifle builds and close-quarters versatility. Built on a standard AR15 upper receiver, this 10.5-inch 5.56 NATO barrel comes with a pinned front sight base, carbine-length gas system, and Magpul MOE SL handguard—everything you need to pair with your lower receiver. Whether you're setting up a home-defense SBR, a truck gun, or an entry-level 5.56 platform, this upper gives you a compact, maneuverable package without compromise.

The 10.5" barrel length keeps velocity respectable in 5.56 while cutting overall length for easier handling in tight spaces. The pinned front sight base pairs with the A2 flash hider for a classic, proven configuration, and the carbine-length gas system runs reliably with standard 5.56 ammunition. The Magpul MOE SL handguard is lightweight, ergonomic, and leaves mounting options open for lights, grips, or other tactical accessories.

This is an upper-only assembly—you'll need to mate it with a stripped lower receiver and source your own charging handle and bolt carrier group. For buyers who want a quality, no-frills Aero upper without the premium price tag of fully-tricked variants, this is a solid platform that works straight out of the box.
