The Sig Sauer SRD556-QD is a rifle suppressor designed for 5.56 NATO platforms. It utilizes a quick detach mounting interface that mates with compatible Sig Sauer SRD taper lock muzzle devices, allowing repeatable attachment and removal without tools while maintaining consistent point of impact. The taper lock design ensures a gas tight seal at the mount point for consistent sound suppression and minimal point of impact shift across repeated mounting cycles. The suppressor body is constructed from 17-4 PH stainless steel and employs a welded baffle stack, creating a durable internal structure that maintains structural integrity under sustained fire.

The SRD556-QD is recommended for use on host firearms with barrel lengths of 10 inches or greater in 5.56 NATO and is rated for full-auto fire. Accompanied by original box, no additional accessories included.
