The SAR-18 is a bullup designed rifle which shortens its overall length. The overall shorter length makes the SAR-18 perfect for both CQB combat and long range shooting as the barrel length available to the user in a shorter overall length. Both the SAR and the M4 have the same stopping power, accuracy and firing rate but the SAR has better maneuverability in place of reloading speed. 30+1 rounds is far more than should be required in a single mission.
