ESS Crossbow Replacement Tri-Tech Frame is the replacement frame for both your ESS Crossbow® and Crosshair™ lenses.  It is also handy for your extra ESS lenses so that you do not have to pop them in and out.

The ESS Crossbow Replacement Tri-Tech Frame provides a universal fit with zero pressure points and is recommended for use without ear cups (See Crossbow Suppressor™ for ear-cup-compatible frame).
