Aero Precision AR-15 Carbine Buffer Kit H3 Buffer

Description

Product Overview

Aero Precision’s AR-15 Carbine Buffer Kit with an H3 buffer is built to help tame overgassing commonly seen on semi-automatic ARs with short gas systems. It replaces the buffer and spring setup with a heavier H3 buffer while using a mil-spec carbine receiver extension tube machined from 7075-T6 aluminum, along with the required end plate and castle-lock nut.

Key Features

• Includes the H3 (heavy) carbine buffer for increased reciprocating mass to help manage overgassing
• Uses a mil-spec carbine buffer tube machined from 7075-T6 aluminum with six-position buttstock slots
• Ships complete with buffer spring, end plate, and castle-lock nut for a straightforward swap
• Helps reduce wear on internal components and can help lower felt recoil compared to lighter buffer configurations

If you’re dialing in reliability and recoil characteristics on a short gas AR build, this Aero Precision carbine buffer kit with an H3 buffer is a practical way to fine-tune the operating system.
