POF USA Rifle Lowers for Sale

Patriot Ordnance Factory, Inc. (POF-USA) of the United States has built AR-pattern rifle lowers in-house since the 2000s, making the lower a core element of its platforms and standardizing a billet, fully ambidextrous Gen 4 pattern by the mid-2010s. Within rifle lowers, POF is distinguished by fully ambidextrous, billet-machined designs that integrate mirrored bolt catch/release, magazine release, and safety controls, along with a proprietary ambidextrous bolt-hold-open system, anti-tilt buffer tubes, receiver tensioning features, and flared magwells for left- and right-handed ergonomics.
