SIG SAUER'S FAST-ATTACH 5.56
The Sig Sauer SRD556-QD offers the same great performance as the SRD556, but in a quick disconnect version. Made from Inconel 718, the SRD556-QD provides a durable solution for short barrel rifle use.
The 5.56mm fast-attach muzzle device system is available in 1/2"x 28tpi threads matching the vast majority of modern sporting rifles in .223/5.56mm on the market today. A secondary retention latch is depressed to remove the silencer from the fast-attach mount, preventing the suppressor from unintentional removal. Sig's fast-attach muzzle device does not require shims to properly mount, allowing for a much faster and easier installation.
CAPITOL ARMORY'S OPINION
The SRD556-QD is a fantastic sounding 5.56 suppressor. Although it is limited in terms of usable calibers, it is much smaller than their 762-QD variant. What it lacks in versatility, it gains through a smaller footprint. One of the most unique aspects of the Sig Sauer QD suppressors is the mounting system. The base of the muzzle devices is torqued to the barrel, with no need for shims or timing. A crush washer is then used inside the mount to time the brake or flash hider. Since the suppressor mounts to the rear portion installed first, there's no worry about incorrect alignment that may lead to a baffle strike. This method makes installation of the fast-attach muzzle device tremendously easier.
