Here Comes the Revolution: Patriot Ordnance Factory’s Latest Falls into the Middle of an Impressive Trio

The Patriot Ordnance Factory (POF) Revolution rifle is a .308/7.62x51 caliber rifle that handles and feels like a .223/5.56, because it’s virtually the same size and weight as the smaller caliber. With its empty weight coming in at just over 7 pounds, it’s slightly lighter than their 5.56 NATO Warhog and just .3 pounds heavier than their 5.56 P45 Edge. POF managed to reduce weight by using some 5.56 parts; namely the bolt carrier and other 5.56 equipment, allowing a shorter overall receiver and reduced weight. The Revolution frame shares parts commonality with the smaller rifle by using the charging handle, bolt carrier, cam pin, buffer, heat sink barrel nut, handguard and five-position gas piston operating system of the 5.56. The barrel extension, bolt assembly, upper receiver and lower receiver are exactly the same size as those of an AR-15. That makes for a .308 that shoots like an AR.

The Revolution features POF’s free-floating monolithic Edge handguard that slides on and keeps the shooter’s grip and accessories from weighing on the barrel. It’s five times thicker than a standard flat top rail. The construction of the handguard directs stress upward and back over the upper receiver.

POF has developed a dual extraction technology that incorporates four small channels cut into the chamber walls that allow a small amount of gas pressure to flow back against the neck of the cartridge. This assists in extraction by breaking the seal between the cartridge case and the chamber and pushes the spent case to the rear as the extractor pulls the case.

The chrome molybdenum barrel is nitride heat-treated for strength and accuracy. Chrome moly has an excellent strength-to-weight ratio and is considerably stronger and harder than standard 1020 steel. A nitride heat-treated three-port muzzle brake controls gas dispersion and reduces muzzle flip. This makes for faster second shots.

The non-adjustable drop-in trigger is set to a 4.5-pound let-off. It’s installed in a hardcoat-anodized aluminum housing. The trigger, disconnect and hammer are all nitride-heated...
