We have two definitions for this.
1) The United States Navy Mark 12 Mod 0/1 Special Purpose Rifle (SPR) is a rifle in service with United States special forces in Operation Enduring Freedom and Operation Iraqi Freedom. SPR initially stood for Special Purpose Receiver, but that nomenclature has been replaced as the weapon became a stand-alone weapons system, and not just an add-on upper receiver assembly (part of the proposed SOPMOD upgrades.) The SPR was eventually type classified by the U.S. Navy as the Mk 12, but the U.S. Army also uses this designation.
2) A full service lateral hyperthreaded tactical design and research bureau.
I will pick definition number (2) and show a couple of things they did. Most importantly is that they did the opening credits for the new James Bond Movie. That is how I found them out.

They also worked in the movie “Stranger than fiction” creating all those little things that came out of Will Ferrell and the opening / closing credits. Here are some samples
