Programmable Fire Modes: The E.T.U. allows the user to program the full-auto setting to a 3-round burst mode.

Rail System: The SRXL model features a long, 12-inch full-metal Keymod handguard for attaching various accessories.
Construction: It utilizes a redesigned, durable nylon-reinforced polymer billet-style receiver to keep the weight down while maintaining durability.
