More about this complete upper

The United States Navy Mark 12 Mod 0/1 Special Purpose Rifle (SPR) is a rifle that has been in service with the United States special forces in Operation Enduring Freedom and Operation Iraqi Freedom. SPR initially stood for Special Purpose Receiver, but that nomenclature seems to have disappeared as the weapon became a stand alone weapon system, and not just an add on upper as part of proposed SOPMOD upgrades. SPR now means Special Purpose Rifle. It was eventually type classified by the Navy as the Mk 12, though the Army also uses this designation.
This weapon system, used by Special Forces units of both the US Army and US Navy, is a heavily modified deviation from the familiar AR15/M16 line of infantry weapons, and thus is chambered for NATO standard 5.56 x 45 mm caliber ammunition. It serves a light sniper/designated marksman role.
The SPR was originally proposed by Mark Westrom, currently president of Armalite, while at the Rock Island Arsenal. The SPR program was an outgrowth of the desire by both US Army and Navy special forces for a rifle with greater effective range than an M4 type 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).

    First AR

    Finally was able to put a couple hundred rounds through this upper this weekend and extremely pleased with it. The quality is there is spades and can be seen and felt as soon as you take it out the box. Performed flawlessly and already itching to take it out to the range again.

    BCM Mk 12 Mod 0

    First and for most I want to say thank you for the really fast shipping. Received my BCM Mk 12 Mod 0 and once opened I could tell it was packed very well. Everything on this upper was flawless and well put together. Got to take it out to test fire it and I couldn't be happier. I was able to get about a 1 inch group maybe a tad bigger using some 77 grain privi ammo i had laying around. Can't wait to get some mk 262 ammo in and stretch it out a ways.
