The LBE Ar15-Upk is a dedicated upper parts kit for AR-15 builders who want quality small parts without sourcing them individually. This kit includes the essential hardware needed to complete an AR-15 upper receiver assembly: a forward assist assembly and an ejection port door assembly. If you're building an upper from scratch or replacing worn components, having these two pieces on hand saves time and ensures compatibility with standard AR platforms.
LBE Unlimited manufactures all their components domestically, with a focus on rigorous quality control and American production. That commitment to stateside manufacturing means you're getting parts built to consistent standards, not sourced from a dozen different suppliers. For AR builders who care where their parts come from and how they're made, that matters.
The forward assist and ejection port door are small but essential—the kind of parts easy to overlook until you need them. This kit bundles them together so you're not caught short when you're halfway through your build. Whether you're assembling your first upper or your tenth, having quality small parts on hand is practical.
