The Etha3M offers players a sleek, fresh approach to ergonomics with numerous notable performance upgrades. Its quick-release bolt assembly makes a huge difference to accessibility and maintenance, typically found on much more expensive marker platforms. The aluminum low-rise feedneck reduces the overall profile of the marker. But it's the new aluminum trigger and mighty FL 3-way that make a serious step forward regarding firepower. The lighter, more responsive, and faster trigger cycling potential is jaw-dropping.
