One of the most-crucial components needed to complete a built of a Heckler & Koch HK417 rifle build is the complete bolt assemblies used on the rifle. Some might even be looking for replacement components to keep their original HK417 running. For that, the Brownells HK417 Complete Bolt Assembly is available. Machined entirely in the USA from 9310 steel, the Brownells HK417 Complete Bolt Assembly is designed for use with 7.62 NATO and includes the dual ejectors and extractor found on the factory-made HK417 bolt. The bolt, ejectors and extractor are all finished with the correct nickel-Teflon finish, making it the perfect piece to finish off a correct HK417.
