Overview
The Armaspec SMB Buffer Kit H Gen 3 is designed to enhance the cycling of your AR-15 by utilizing a heavy buffer weight, which contributes to better recoil management and may improve reliability with a variety of ammunition types. The H buffer weight helps to slow down the bolt carrier group during cycling, which can reduce felt recoil and increase overall performance in semi-automatic builds. This buffer is commonly found in builds intended for more robust shooting applications, especially when paired with heavier springs or tuned for specific ammunition loads.
