What is the BROWNELLS - BRN-4 HK416 Combination Wrench?

BROWNELLS BRN-4/HK416 COMBO WRENCH

The Brownells BRN-4/HK416 Combo Wrench is a compact, multi-function armorer's tool designed to handle the most common assembly and maintenance tasks associated with BRN-4 and HK416-pattern rifles. Combining multiple essential wrench functions into a single rugged tool, it provides a convenient solution for armorers, builders, and firearm enthusiasts working on compatible rifle platforms.

Designed as an all-in-one maintenance tool, the wrench incorporates dedicated interfaces for castle nuts, barrel nuts, and flash hiders, while an integrated 1/2" drive opening allows use with a torque wrench for precision assembly operations. Its compact design makes it easy to keep on the bench, in a toolkit, or in a field maintenance kit without sacrificing functionality.

Constructed from hardened steel for strength and durability, the BRN-4/HK416 Combo Wrench is purpose-built for compatibility with Brownells BRN-4 components, many HK416 variants, and select Geissele barrel nut and handguard systems.
