C.A.T. Alleycat 556 QD 718 Suppressor (5.56mm, Inconel 718)
The C.A.T. Alleycat 556 QD 718 is a 5.56mm suppressor built around the ALLEYCAT “Surge Bypass” design and a proprietary 1x16LH QD interface. This model is constructed from Inconel 718 for high-heat durability in hard-use firing schedules.
The Alleycat 556 QD uses left-hand QD threads to help keep the muzzle device on the host when removing the suppressor, and features a DLC exterior finish.
