The M16 SPR is a rifle used by Ghost Recon snipers.
Real-world overview Edit
The The United States Navy Mark 12 Mod 0/1 Special Purpose Rifle (SPR) is a rifle used by United States Special Forces as a designated Marksmen weapon.
The SPR is used by the U.S. Army as well as the U.S. Navy. It is a heavily modified Marksmen variation of the AR15/M16 line of weapons. The SPR concept was originally proposed by Mark Westrom, currently president of Armalite, while working at Rock Island Arsenal. The program was an outgrowth of the desire by both US Army and Navy special operations forces for a rifle with greater effective range than an M4 Carbine but still shorter in length than a standard issue M16A2/A4. The SPR program appears to have grown out of both the SOPMOD Block II program, and the U.S. Navy SEALs 'Recon Rifle' (a 16" flat-topped AR-15/M16 Carbine). The Naval Surface Warfare Center, Crane Division (often referred to as NSWC-Crane or "Crane") essentially expanded on the Recon Rifle, an expansion that some SEALs maintain was a waste of time and resources.
The exact history of the Mk 12 is still in debate, but there appear to be either four or five prime iterations of the weapon, culminating in the most recent Mk 12 Mod 1 version. One progression has four models: SPR Proto 1, SPR Proto 2, Mk 12 Mod 0 and Mk 12 Mod 1. The other progression has five models: SPR, SPR/A, SPR/B, Mk 12 Mod 0, and Mk 12 Mod 1. The specifications in this article follow the second progression.
There is also increasing agreement among observers and small-arms historians that different U.S. military service branches typically deploy different iterations of the SPR. Available evidence, including both U.S. Department of Defense (DOD) photographs and privately-obtained photographs (like the ones shown below), consistently show most US Army SF operators using the Mk 12 Mod 0, while NAVSPECWAR operators and US Army Rangers have been identified as using the Mk 12 Mod 1 version.
The SPR was not well-known to the general public until recently, but it has been featured prominently both in media photos of the Iraq conflict and in interactive video games such as the government-created America's Army: Special Forces and in Tom Clancy's Ghost Recon 2. Civilian copies of the SPR (commonly called "SPR clones") have also become quite popular among shooters and collectors in the U.S., with several reputable builders of AR-15 style rifles making civilian-legal copies of this accurate rifle.
