mid-range gas carbine

The Mid-Range Gas Carbine (MRGC) is based on the SWORD Defense Systems renown Mk-17 rifle. In 2019, Naval Special Warfare Command (NSW) ran a small competition for a 6.5 Creedmoor Mid-Range Gas Gun (MRGG). Taking the specifications of the requirement and lessons learned from the rigorous testing regimen, SWORD Defense Systems has produced an ultra-accurate and reliable semi-automatic platform that is capable of sub-minute accuracy with a variety of 6.5 ammunition. The MRGC moniker is a nod to the ultra professional end-users and program officers at NSW that invited SWORD to compete and provided the opportunity to address their requirement. After taking feedback from end-users, implementing enhancements, and a rigorous testing regimen, SWORD Defense Systems added the MRGC to the Defense product line.

The SWORD Defense Systems MRGC is offered in various barrel lengths and is chambered in 6.5 Creedmoor.
