Silverfield Ordnance, sometimes abbreviated as SO, is a weapon manufacturer in Call of Duty: Modern Warfare, Call of Duty: Modern Warfare II and Call of Duty: Modern Warfare III. Silverfield Ordnance appears to have two separate logos: one is a capital S protruding through the top of a circle, the other is a capital SF within an oval. Unfortunately, most all of Lockwood's attachments (and multiple other attachments from other manufacturers) also place the Silverfield Ordnance "S" in a circle logo on their attachments, confusing matters.
