The P415 was engineered over 10 years ago to be virtually unstoppable in unfavorable conditions. It is a product of continuous development and improvement to the AR platform that no other rifle company has attempted. The reliability has been tested time after time, and the operating system perfected. E2 Extraction Technology, complete ambidextrous fire controls, modular free floating rail platform, and numerous internal improvements make it the pinnacle of all-purpose 5.56 caliber sporting rifles. For 2017, we've cut the bulk. To minimize weight and maximize shooter comfort, the new P415 edge features a redesigned handguard, reducing the size from the original by nearly 20%, making the width a mere 1.75 inches. Not only does this drop the weight down to 7 lb, it provides even better ergonomics to the shooter. The P415 simply will not fail when you need it most.Features:Ambidextrous bolt release with enhanced bolt catchReceiver tension screwsOversized mag well flareAmbidextrous recessed finger restAmbidextrous magazine releaseOversized integrated trigger guard with grip reliefAmbidextrous bolt hold openPOF-USA's patented E2 dual-extraction technology consists of four small channels cut into the walls of the chamber allowing a small amount of gas pressure to push against the neck of the spent caseNitride heat-treated barrel – every shooter knows that the beating heart of their rifle is their barrelTriple port muzzle brake – designed to precisely compliment the POF-USA platform, our nitride heat-treated muzzle brake controls gas dispersion and reduces muzzle riseOversized heat sink barrel nut – the patented oversized heat sink barrel nut is one of the most significant innovationsDrop in trigger system – this single-stage, non-adjustable, drop-in trigger boasts a solid 4.5 lb pull weight and is pre-assembled in hardcoat anodized aluminum housing for immediate competition, hunting, and tactical applications right out of the boxGas piston bolt carrier group – our 1-piece high-phosphorus nickel coated bolt carrier is manufactured with the mechanical key built into the body and positioned behind the cam pinOur patented roller cam pin is just one more example of how we strive to reduce friction and drag in the actionOur Mil-Spec aluminum anti-tilt buffer tube features "carrier cradle" extensions to ensure that the carrier is always supported by the buffer tube even when the bolt carrier is fully forwardThe POF-USA adjustable gas system consists of three major components, the gas plug, gas piston and operating rodThe patented modular railed receiver (M.R.R) is POF-USA's crown jewel for precision and extreme rigidity
