Building an AR15 upper receiver from scratch means sourcing individual components—a tedious hunt across multiple suppliers if you're not careful. The Aero Precision AR15 upper parts kit bundles the small but critical pieces you need to complete your upper assembly in one go. This kit brings together the forward assist assembly, ejection port cover assembly, and all the springs and pins required to get them functioning, saving you the frustration of tracking down each part separately and the risk of ending up with incompatible pieces.
Aero Precision has built a solid reputation among AR builders for attention to detail and reliable fit-and-finish. These components handle the daily mechanics of your rifle—the forward assist keeps your bolt carrier group locked home when you need it, and the ejection port cover prevents dirt and debris from finding their way into your receiver. Quality here isn't about flash; it's about parts that work predictably, shot after shot, whether you're at the range, hunting, or running drills.
This kit works as part of a larger upper receiver assembly project. You'll still need your upper receiver, barrel, barrel nut, handguard, and bolt carrier group—but the upper parts kit handles the fiddly hardware that's easy to lose or mix up. If you're assembling your first AR or building your fifth, having these components matched and ready to go keeps the build moving forward without delays.
The Aero AR15 upper parts kit supplies the forward assist assembly (spring, roll pin, and the assembly itself), plus the complete ejection port cover assembly (door, rod with c-clip, and spring). These are the main operating components that mount to an AR15 upper receiver.
Yes. This kit does not include the upper receiver itself or barrel components. You'll need to source a compatible AR15 upper receiver, barrel, barrel nut, handguard, and bolt carrier group separately to complete your upper assembly.
Aero Precision components are designed to Mil-Spec AR15 standards. Verify your upper receiver is standard AR15 spec before purchase to ensure compatibility.
We don't have specific tool information for this kit in our product details. We recommend consulting an AR15 assembly guide or manual for your build, or reach out to our team if you have questions about the installation process.
