About this prize
The Sig Sauer MCX Spear is a .277 Fury/6.8x51mm semi-automatic rifle built as the civilian-legal version of the U.S. Army's next-generation squad weapon platform, chambered for the high-pressure hybrid-cased .277 Fury round developed alongside the military's NGSW program. This 16-inch-barreled Coyote-finished configuration runs Sig's short-stroke gas piston system for reliable cycling and reduced fouling, feeding from AR-pattern magazines built to handle the round's higher pressures. The folding, adjustable stock and free-float M-LOK handguard make it adaptable for a wide range of optics and accessories. This is a premium, cutting-edge semi-auto rifle built around one of the most powerful intermediate cartridges on the market.
