The SCARMK17 is a high-power assault rifle. It has high damage, good ammunition capacity, and a reasonable rate of fire. It ties with the FNFAL ACOG in terms of power-per-shot, but has a slightly lower rate of fire and weighs one block less. It suits a role similar to other assault rifles, but has enough power to go toe-to-toe with the big guys.
Place your shots carefully; use short bursts to conserve valuable ammo.
