Aero Precision

Resumen

The Aero Precision EPC-9 Threaded Upper Receiver is a stripped upper designed specifically for the AR-9 platform, allowing builders to create custom fitments for their 9mm setups. The inclusion of LRBHO (Last Round Bolt Hold Open) functionality enhances reliability by ensuring the bolt locks back after the last round is fired, which is essential for streamlined reloads. This upper receiver is commonly used in builds that prioritize compactness and versatility, often paired with compatible lower receivers for a complete AR-9 configuration.
