The .277 Fury is one of the most modern bottleneck rifle cartridges currently available on the market. The .277 Fury round was originally developed by SIG Sauer for the U.S. military’s NGSW (Next Generation Squad Weapons) program. A unique aspect about the .277 Fury is that it relies on a hybrid brass and steel case design in order to contain the higher pressures that it uses drive a 6.8mm projectile at muzzle velocities averaging around 3,000 fps, with projectile weights from 113 to 155 grains. The .277 Fury round has the potential to offer magnum-rifle-cartridge-like performance in a standard or “short action” length cartridge. For semi-automatic rifles, the .277 Fury works well with DPMS pattern AR-10 lower receivers, which is what Bear Creek Arsenal’s new .277 upper receiver assemblies are designed for.
