The .277 SIG FURY cartridge utilizes a hybrid case with a steel base, allowing for a maximum pressure of 80,000 PSI. This generates a 135gr projectile velocity exceeding 3000 fps, providing flatter trajectory and enhanced energy downrange. The direct gas system is engineered to handle this high pressure reliably, making the MCX-SPEAR Direct a robust platform for demanding use.
