Sig Sauer Clutch-Lok QD Flash Hider 5.56mm 1/2×28 25°

The Sig Sauer Clutch-Lok Tapered QD Flash Hider is a purpose-built QD mount that doubles as a flash hider for 5.56mm SLX and SLH suppressors. It provides a quick-attachment interface for compatible suppressors and reduces muzzle signature when the suppressor is removed. The unit uses a tapered shoulder interface designed for SIG Sauer Taper-Lok barrels and standard 1/2×28 tpi muzzle threads. Its compact overall length keeps the mount profile minimal while delivering repeatable attachment performance.
