More 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).
 
DLC Coating stands for diamond-like carbon coating, and is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance.

    Mk12 Upper

    Large tooling marks on rail and the barrel is visibly off center in the free float rail. I understand it may be in spec, but when you are paying this much the lack of attention to detail is disappointing. Have several other military clone guns from FN and the quality is noticeably different.

    Great Product!

    Ordered the Mk12 mod 1 upper from BCM, it took some time to process due to the “cost” but I understand. The upper did arrive on time and in a timely manner. Once set up on a lower I had and a good optic I took it out to zero. Not only was it the fastest rifle to zero I’ve ever had, it shoots lights out from the first round. It’s had about 400 rounds put through it now and with its favorite flavor of 77grain OTM it’ll put down 1/2 inch groups all day @100 yards easy, with bags and a controlled trigger finger it’ll do even better. Zero malfunctions whatsoever and did I mention it was accurate? My only real complaint would have to be that when it arrived it had enough oil on it to oil just about every other gun in the safe with what I wiped off the Upper. Bottom line is if you purchase this up you will NOT be disappointed. Great job BCM!!!

    Very satisfied with the quality of this upper.
    I like that the gas block is pinned .. gives me peace of mind that it won't ever move around.

    Thanks!

    Awesome Upper!

    Bought this to build a MK 12 replica. I know it is not exact, but an amazing upper! Got with the medium charge handle and BCM MK12 suppressor adapter. No complaints so far! Paired with an Aero Precision lower. Awesome Combo!

    I am very pleased with my new upper. I do wish that you had dealer pricing. My whole sellers sell some of your items, but not all. Thank you for making great products!

    Excellent but....

    Love it but I could not believe I was unable to upgrade parts such as bolts or trigger. The upper itself is a piece or art.
