About Patriot Ordnance Factory (POF-USA) Firearms

Founded in 2002 by aerospace engineer Frank DeSomma, Patriot Ordnance Factory (POF-USA) was created to produce high-quality firearms for both civilian and professional use.

DeSomma also wanted to solve two common problems with gas impingement systems in dusty conditions found with the traditional AR-15: carbon fouling and a short-barreled timing issue.

Through POF-USA's continued commitment to advancing firearm technology, the company has successfully contributed numerous innovations, including:

  • Regulated Short-Stroke Gas Piston System
    Unlike traditional gas impingement systems, POF-USA's gas piston system offers a cleaner, cooler, and more dependable operation.

    The system's design, with fewer moving parts and reduced fouling, promotes enhanced reliability and a longer lifespan for the firearm.

  • E2 Extraction Technology
    Unique to POF-USA, the E2 dual-extraction system integrates four small channels into the chamber walls, optimizing the extraction process.

    This innovation promotes a reduction in operational failures and an extension in component lifespan.

  • Roller Cam Pin
    This design modification addresses friction in the firearm's operation.

    By integrating a Roller Cam Pin, friction in the upper receiver is minimized, promoting smoother functionality and extending the overall life of the firearm platform.

Today, POF-USA specializes in designing and manufacturing AR-style rifles, upper receivers, lower receivers, and miscellaneous gun accessories.

Their continued mission revolves around offering optimal firearms to those who value the principles of the Second Amendment and Patriot Ordnance Factory AR rifles are utilized by owners domestically and abroad, serving professional and civilian needs.
