Overview
The Aero Precision AR-15 H3 Buffer is designed to provide optimal performance for your AR-15 platform. With its heavier weight, it helps to reduce felt recoil and improve cycling reliability, making it a solid choice for builds that benefit from a more controlled shooting experience. This buffer is commonly found in mid-length gas system configurations chambered in 5.56 NATO, where it can enhance overall function and accuracy.
