Description
H2 Buffer: Weighs 4.66 oz. The H2 Buffer is an excellent choice for most AR-15 calibers. This has the same weight as an M16 buffer out of an A2 stock, making it a great option for heavier bullets, such as 7.62×39 and 6.5 Grendel. Almost all our Johnson Dynamics Uppers are designed to use this H2 Buffer.
