SIG Silencers SRD556Ti 5.56 Rifle Silencer 1/2×28 tpi Direct Thread
The SRD556Ti is a Grade 5 Titanium direct thread silencer. The 1/2″x 28tpi threads match the vast majority of modern sporting rifles in .223/5.56mm on the market today. The rear mount has wrench flats to torque the silencer to the barrel. These wrench flats can be used as a location to “pin and weld” the silencer to make a shorter barrel over 16″ in total length.
