The BAR MK 3 relies on a short stroke gas piston design to operate the action. This design mitigates shooter-perceived recoil and reduces excessive carbon residue that many modern gas-impingement designs vent into the moving parts of the action. Like most modern sporting rifles, the BAR utilizes a multi-lug rotary bolt that locks securely for improved strength and accuracy.
