The HK ETHA3 delivers a competitive electronic marker experience without the premium price tag.

HK Army and Planet Eclipse have teamed up to bring you the first-ever ETHA3 with a metal body, featuring the stunning HK Army signature Hive design. The custom milled hexagon pattern is a testament to the meticulous craftsmanship that ensures ultimate accuracy on the field.

The ETHA3's sleek approach to ergonomics, coupled with some notable upgrades takes the platform into a new competitive realm. Its quick-release bolt assembly makes a huge difference to accessibility and maintenance on, or off the field. The aluminum low-rise feedneck reduces the overall height of the marker for a tighter, more compact player profile. And the new aluminum blade trigger brings a sharpness and responsiveness only found on more expensive marker platforms.
