About this complete upper receiver group

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).

    Awesome Upper

    As always great workmanship and excellent quality. I have not had a chance to take it out yet, but with all my BCM rifles they are excellent. The materials are also excellent as very few if any manufacturers use 410 stainless Steel.

    BCM Mk 12 Mod 0-Bravo (PRI Black)

    Couldn't be happier with my purchase. I bought this upper for a build I had planned for sometime. The quality is top notch. I have taken my completed rifle to the range as of this date and will update in the future.

    Superb craftsmanship, excellent accuracy.

    I just received my upper today, the first time I have gotten one from BCM, and I have been a fan of the AR platform for years. My regrets I had not shopped BCM before! The craftsmanship on this MK12 is excellent. I am pleased to no end on my purchase and have not even had the chance to shoot it yet. I think the black finish compliments the parkerized receiver I mounted it to, quite a nice effect in my opinion. Once I get a chance to put a scope on it and dial it in I will report back, but I expect no issues at all.

    Thanks to BCM also for the goodies they included in the order, that made my day too.

    Update October 2010
    Took awhile to get out to the range, but once I did I was very very happy with the results. Shooting on a very windy day at 100 meters using Hornady 77gr match grade ammo I shot a 5 shot group I could cover with my thumb. I can't wait to see what this upper will do with better weather and a lighter trigger in my lower.

    Kudos to BCM for such a fine product!
