Nothing beats the sound amplification of the Peltor Comtacs. The Mk 3s are probably the most iconic and widely used Comtacs used. I have it upgraded to a very comfortable fit so you can wear it all day without any pain or even noticing it's there. The arc adapters are genuine 3M Peltor Comtac Arc Adapters. They also come with the Crye airframe adapters. I have the original barn. coversd by a Multicam wrap made by US Tactical Sewing. The headset is an great working condition and uses AAA batteries so its very easy to replace it's power. Please feel free to ask questions or request more pictures I am not playing airsoft anymore as I am too busy. Id really like the cash! I am in no hurry. I just never find time to use them. If you have anything that may be of interest let me know!
