The company employs various features to keep heat away from the receiver and to cool the gun as rapidly as possible. In an independent torture test performed a few years back, a POF was subjected to an unrealistic schedule of full-automatic fire: a series of Beta Mags were used to fire 1,000 rounds within minutes.

Not a big gun … Because of DeSomma’s engineering background, he and his team tackled the design of the entire AR one piece at a time, looking for ways to make things stronger, make them operate more smoothly with less friction and drag, and even produce the gun with fewer moving parts.

Talkin’ ’Bout My Generation POF’s Gen-4 Carbine is Accurate, Ergonomic and Runs Like a Sewing Machine. POFs have a reputation for shooting small groups, and one of the reasons for that can be found in their gas system. A button above the right-side magazine release is used to drop the bolt into battery, and an additional magazine release is positioned on the left side of the lower. 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. His only comment was, “When I buy it, I’m gonna’ put an ambi charging handle on it.” A pretty solid endorsement from a guy who has used just about every modern combat carbine on the planet.

What many consumers don’t realize is that, regardless of brand, the majority of AR components are produced by a small number of manufacturers and then assembled by the company whose name is stamped on the receiver. The gas system is easily removed from the front of the fore-end and does not require the tube’s removal so optics do not need to be re-zeroed after the gas system is serviced. Eventually, the hardened steel surface of the pin reciprocating on the softer surface of the aluminum receiver can cause undue wear on the firearm. Popping the catches on the obligatory black plastic shipping case, the first thing that you notice on the new 5.56mm rifle is the hand-guard.

For starters, the piston design requires less gas than most others, so the gas port is smaller in diameter—less gas being siphoned from the bore means less heat to contend with. The barrel itself is cooled by an innovative aluminum barrel nut that physically draws heat away from the steel, and pronounced flutes in the barrel provide additional surface area for heat dissipation. Small rail sections can be placed in various locations on the fore-end as desired, without the weight and abrasiveness of a fully-railed design. The barrel is black nitrided inside and out, which eliminates the need for chrome lining and actually raises the Rockwell hardness of the steel—the system components are also nitrided.

EVERYTHING SHIPS FREE FREE SHIPPING FOR CLUB MEMBERS, ALL ORDERS $49+ Once fired, the expansion of the case head creates a press-fit seal between the cartridge case neck and the AR’s chamber in addition to the friction caused by the nearly parallel planes of the case body and the chamber wall. The gas key on a direct-impingement AR is the link in the chain between the propellant forces surging through the gas tube and the working parts of the receiver. What it calls E2 extraction technology, is a series of four channels that run parallel with the cartridge in the neck of the chamber. The slotted free-float fore-end of the P415 extends over the top of the upper receiver, providing an uninterrupted Picatinny rail as well as bridging the major components together mechanically. They have been highly reliable and absolute tack drivers on accuracy. © 2021 Recoil Magazine Report Save. Firearms & Survivalists Lifestyle Unlike Eugene Stoner’s original design that uses a gas tube to direct propellant gases into the bolt carrier key to cycle the bolt, DeSomma’s design uses a piston and operating rod to transfer energy back into the bolt and force it rearward.
