Description
The H4 buffer assembly, also called the H3+, was developed at SA in recent years.
It is an internally modified design which gives the standard H3 buffer greater secondary impact force,
as if the assembly contained a 4th weight.
Used in special ops 5.56mm weapons with 10, 10.3, and 11.5 inch barrels.
