Sig Sauer Clutch-Lok QD Muzzle Brake 7.62mm 5/8-24

This Clutch-Lok QD mount from Sig Sauer serves as both a quick-detach mount and a muzzle brake for 7.62mm SLX/SLH suppressors. It provides a 90-degree tapered shoulder interface intended for use with non‑Sig Sauer barrels and uses a 5/8-24 thread pitch for mounting. The design allows rapid attachment and removal of the suppressor and reduces felt recoil when the suppressor is not installed. It is intended for use on platforms chambered in .308 / 7.62 NATO.
