Alexander’s rifle was cleaned for the first time after 16,000 rounds, not because the P415 needed it, but because he was teaching a course for the State Department that mandated a class on cleaning and maintenance. In a memo to Frank Desomma, President of POF, Alexander stated that he had yet to experience a single malfunction except one that was attributable to a faulty magazine very early in his use of the P415 upper. Alexander, a retired US Army Special Forces Chief Warrant Officer with 26 years’ experience, is not one to make statements such as these lightly or in jest.

- All of our weapon systems are 100% pure American made.
The latest POF carbines have a “spine” atop the upper receiver rather than a MIL-STD-1913 rail that allows the one piece P-4SX receiver/handguard to be slid into place and retained with bolts, essentially making for a rigid two-piece upper receiver. The P415 barrel is fluted along its entire length for rigidity and heat dissipation. The flutes offer a greater surface area, so heat is more rapidly dispersed than with standard heavy barrels. Flutes also stiffen the barrel and improve accuracy by reducing barrel vibration as the rifle is fired.
