The Armageddon Gear Suppressor Mirage Cover significantly reduces and delays the effects of suppressor mirage on the rifleman's ability to identify and engage his target. Highly-secure design stays in place during vigorous movement, yet can be adjusted or removed in seconds. Adjustable cord ensures custom fit and retention. Cover design ensures NO contact areas between nylon shell and hot suppressor. Our original Mirage Cover model is the most proven suppressor cover on the market and is rated for mirage mitigation on bolt-action and semi-automatic precision rifles. The Hi-Temperature model is new for 2017 and is rated for use on carbines with a high rate of fire, up to a suppressor temperature of 800 degrees F. Allow your suppressor to cool to avoid damage beyond 800 degrees F, especially with Titanium suppressors.
