Frequently Asked Questions

What makes the POF P308's operating system unique?

The POF P308 features a piston-driven operating system, distinct from the direct impingement system of standard AR platforms. This design aims to reduce heat and carbon buildup in the action, enhancing reliability. It also uses fewer moving parts and no return spring compared to other piston systems.

How does POF's E2 extraction technology work?

POF's E2 extraction technology uses four channels along the cartridge. When fired, these channels direct expanding gases into the cartridge shoulder, breaking the seal between the case neck and chamber wall. This ensures that spent casings extract smoothly and reliably.

What caliber is the Patriot Ordnance Factory P308 chambered in?

The Patriot Ordnance Factory P308 is chambered in the .308 Winchester caliber. This caliber is known for its harder-hitting performance compared to smaller rifle cartridges.

What are some of the notable external features of the POF P308?

The POF P308 boasts a monolithic upper receiver, a 16 1/2 inch fluted nitride-treated barrel, and an adjustable buttstock. It is shown with a Magpul STR buttstock and Magpul grip, and this particular model features a burnt bronze Cerakote finish. It also includes a range of ambidextrous controls.
