Maxim Defense CQB Buffer & Spring H1 4oz - Tungsten

The Maxim Defense CQB Buffer & Spring Combination is a factory replacement buffer and spring assembly engineered specifically for the Maxim CQB line of stocks and pistol braces, including the CQB Generation 2 platform. Built around an H1-weight buffer at 4 oz, this combo delivers the standard H1 tune recommended for Maxim's ultra-compact CQB stock system, helping maintain reliable cycling on AR-platform builds.

The buffer is machined from tungsten with a natural finish, providing the mass density required for the H1 rating in a compact package designed as a direct-fit replacement for owners of compatible Maxim CQB stocks and braces on AR-platform carbines and pistols.
