A sound suppressor mounting system to a firearm having a flash hider, the flash hider having a series of annular grooves and vertical flats on the body of the flash hider, and comprising: (a) a body; (b) a primary latch; and (c) a secondary latch; whereby the body has a bore for receiving the flash hider of the firearm, said bore having a forward support and a rear support and said front support having a surface for limiting the forward travel of the flash hider into the body, and a transverse recess for receiving the primary latch; the primary latch has at least one rib on the internal surface of the latch, a pivot point, and is movable in a vertical plane to the axis of the bore between an unlatched and a latched position; the secondary latch has a handle, a pivot surface, a lock surface, and is movable in a vertical plane to the axis of the bore between an unlatched and a latched position; and upon insertion of the flash hider into the body, the primary latch is moved downward to a latched position, the at least one rib on the internal surface of the latch interfaces with a groove on the flash hider, and whereby the secondary latch, upon the primary latch being in the latched position, is then rotated downward around the pivot point on the primary latch to a latched position, thereby locking the primary latch to the body, the body to the flash hider, and the secondary latch to the body.
