Custom-grade accuracy is now within reach of virtually every hunter. Building upon expertise that's dominated bolt-action technology for more than 50 years, Remington's engineering team started from scratch and combined their most advanced, accuracy-enhancing features to create an all-new platform. The Model 783 Heavy Barrel features a picatinny rail, SuperCell Recoil Pad, and a flat dark earth synthetic stock that contains a high nylon fiber content, which promotes superior strength and rigidity. Also helping deliver those inherently tight groups is a precision button-rifled barrel. For shot control, it's equipped with the crisp new CrossFire trigger system that's user adjustable to suit your preferences. The Model 783 features a steel detachable magazine with a steel latch. Like with all Remington bolt actions, expect a lifetime of rock-solid reliability. From the next generation in a legendary bloodline. The Model 783 in 450 Bushmaster sports a heavier 16.5" barrel and a muzzle break to manage some of the recoil that the 450 Bushmaster dishes out.
