The EXFIL Peltor Quick Release Adapter Kit is compatible with all Peltor COMTAC systems. By allowing the COMTAC system to mount directly to the helmet accessory rail, it eliminates the rigid metal headband, providing better fit and comfort. The tool-free attachment mounts directly to the quick release slot on all EXFIL Rail 2.0, EXFIL Rail 3.0 and EXFIL SAR accessory mounting systems. Open and closed positions allow quick donning and doffing of helmet. Wiring is easily routed in or outside the helmet shell. The kit includes one boom microphone adapter.
