Patriot Ordnance Factory 00328 Bolt Assembly 5.56x45mm NATO Nickel Plated Steel AR-15/M16

The Patriot Ordnance Factory 00328 Bolt Assembly is a direct-replacement bolt manufactured for the AR-15 and M16 platform in 5.56x45mm NATO (also fully compatible with .223 Remington). The bolt is machined from steel, nickel plated for corrosion resistance, and heat treated to MIL-SPEC for long service life in both direct-impingement and piston-driven rifles.

This complete Bolt Assembly ships ready to drop into your existing carrier - the extractor and ejector are already installed at the factory, so installation is a straightforward swap with no extra fitting required. POF specifies this nickel-plated bolt for use in piston-driven AR-platform rifles, making it a factory-spec replacement or upgrade for any AR-15 / M16 build running a piston operating system, while still functioning reliably in standard direct-impingement uppers.

Finished in a durable Nickel Plate and built to POF's exacting standards, this bolt assembly is a clean, quality-controlled way to refresh a worn AR-platform bolt or complete a service build with a trusted component.
