Overview

This replacement tension screw is designed to help fine tune the fit between an upper and Aero Precision Gen 2 lower receiver. It installs in the grip tang and is tightened against the upper receiver to reduce wobble at the interface. Compatible with any standard AR-15 upper receiver, it is intended for users who want a more precise receiver fit without changing the core setup. Aero Precision notes that this screw is already included with Gen 2 AR15 and M5 lower receivers, making this a spare or replacement part rather than a standalone upgrade.

Considerations & Trade-offs

  • This is a replacement tension screw, so it is only useful if you need to replace the original part or want a spare on hand.
  • It is intended for Aero Precision Gen 2 lower receivers, so compatibility is not universal across all AR-15 setups.
  • The screw is used to fine tune upper-to-lower fit, but it does not change the underlying receiver design or eliminate the need to verify proper fit during assembly.
  • Because it works by tightening against the upper receiver, adjustment should be done carefully to avoid over-tightening.
