The Hush XL is a mock silencer barrel extension that fits onto almost any airsoft sniper rifle, AEG, or GBB gun. It was originally designed for seamless integration with the ASG Sportline SSG 69 P2 and AW .308, but it can be fitted onto any barrel with a 14mm CCW threading, or combined with the included adapter to fit 23mm CW threading. The Hush XL features a tight internal BB guide and a matte black metal alloy frame with silver trademarks.
