Mk12: A BRIEF HISTORY (as authored by "LGT" & "FL")

Mk12 Special Purpose Rifle (SPR)

Scoped versions of the M16 rifle existed as far back as the 1960s. Like nearly all historic military rifles, the M16 went through decades of efforts to improve its accuracy, both in the military and civilian marksmanship communities.

The need for the SPR dates back to the late 1980s and early 1990s when the 7.62mm M21 sniper rifle, a semi-automatic weapon of Vietnam vintage, was replaced by the M24 sniper rifle, a bolt action weapon. The M24 was originally specified to be a .300 Winchester Magnum, but the Army decided to field it in 7.62 NATO for a variety of economic reasons. This left the M24 in the unenviable position of being the worst of both worlds in the eyes of snipers at the time, since it lost the fast-shooing, semiautomatic capability of the M21, but did not gain the range advantage of the .300WM. This compromise left a vacant requirement for a fast-shooting semi-automatic sniper rifle. This need was most apparent in the US Army Special Forces (SF) community, since the other commands within the Special Operations Forces structure filled that need with Knights Armament Corporation's SR-25 sniper rifle.

Army SF, being prohibited by its leadership from procuring the SR-25, sought the next best alternative, namely a Special Purpose Receiver (SPR) kit to convert the Army SF M4 carbines into highly accurate rifles. In late 1998, at the request of SFC Steve Holland of 5th Special Forces Group, and the approval of the SOPMOD joint IPT, the Special Operations Peculiar Modifications (SOPMOD) Program Manager, Troy Smith, authorized the purchase of 5 sets of commercial items as an SPR experiment.

The original requirement was for USASOC, mainly the SF Groups, as WARCOM had the MK11, 7.62mm system. Once the SPR requirement was developed and demonstrated through experimentation, most of the other commands in USSOCOM added themselves to the Basis of Issue Plan (BOIP). The USSOCOM requirement for the SPR, with improved ammunition, was approved in July 1999, as part of the SOPMOD Kit, Operational Requirements Document, Version 5 (ORD 5).

Further initial development included several variants of the SPR and new ammunition that were compatible with the M4 carbine's lower receiver. It was found that standard issue M855 5.56mm ammunition was not consistent enough to meet the requirement. In 2000, based on an upgrade requirement to provide a match-grade trigger to the design, Mr. Paul Miller, the SPR project manager, discovered an opportunity to pick through over 15,000 M16A1s that had been sent to Crane for destruction. Realizing that these M16A1 rifles, some of which were virtually new, could be used as "free lumber" to build full SPR weapons, Paul selected several thousand rifles to be set aside for the new SPR project. The SPR underwent a minor but significant name change, with the R having originally stood for "Receiver" now standing for "Rifle"

The new weapon system was worthless without a matching round of ammunition to obtain the performance required. The PEO-SP USSOCOM authorized the new round that became Mk262 as part of the Mk12 system in August 2000. Paul Miller and his SPR team refined the 77-grain prototype ammunition and built approximately 124 SPR Rifles in the summer of 2001. These were finished just in time to ship out to Army SF in late October 2001, to be used in the first invasion of Afghanistan. The SPR rifles were extremely well-received, and the SOF combat units ordered hundreds more.

In May 2002, USSOCOM removed the Mk12 and other complete weapons projects from the SOPMOD Program and placed them under the newly-formed USSOCOM Weapons Program. The fielded weapons included two versions (Mk12 Special Purpose Rifle Mod0 and Mod1). Fielding has since been structured for Mk12 Mod1 Special Purpose Rifle only. This rifle is used by Joint USSOCOM Commands and the USMC in combination with M262 (AA53, 77 grain) ammunition. Formal fielding of the full-rate production version of the Mk12 rifle and ammunition occurred in May 2003 and was completed in FY '04.

In 2012, as the decade of war on terrorism was winding down and the SCAR weapon system began replacing the requirement for the Mk12, USSOCOM and Naval Special Warfare divested themselves of the Mk12 weapons system, and the Mk12 is now being looked at to fill a Designated Marksman Role within Brown Water Navy commands.

The following parts lists and substitution parts was compiled by lancecriminal86 over the course of a LOT of research. Read up and pay attention!

Below are the 100% .mil-spec parts lists to build a true SPR or Mk12 clone. Some of these parts are no longer manufactured and will require much effort and money to locate through forums and online brokers. Keep in mind the rifles were built off donor M16A1s, hence the prevalent A1 parts in the lower receivers and the BCGs. They were also first configured using parts available from 1998-2004, and most are inferior in some ways to newer designs. If this bothers you too much, STOP NOW.

The rifles were issued as a kit in a Pelican 1700 case with cutouts. The kits included the rifle with suppressor, optic, bipod, an Eagle TAS-1 UMSS sling (unobtanium and also absolute crap), with a Dewey 1-piece cleaning rod plus Otis cleaning kit, and a cutout for magazines. An operator's manual was also included, however these have not been officially released for public consumption. However, the manuals are out there, and some companies building Mk12 uppers include one. Whether these are official .mil operator's manuals or specially made is currently unclear as the manual itself still contains language that it is not for distribution.

- Alternate .mil-spec parts due to NFA, NLA parts, or changes in name/markings for current production in [brackets]

- Extra notes about parts or availability are in (parenthesis)

LOWER
Lower receivers were standard across the SPR/Mk12 variants and the only variations would be between grips, stocks, and buffers. Most were marked either Colt or GM Hydramatic. All other parts were the same in regards to the lower parts. One caveat is the trigger, as the program originally selected the Knight's Armament 2-stage Full Auto Match trigger. Later on, some issues regarding negligent discharges occurred, and Geissele SSF triggers ultimately found their way into the Mk12 family. Whether 100% of all Mk12s eventually received the Geissele trigger isn't clear, so either is acceptable.
  • Lower: M16A1 pattern [Nodak Spud NDSA1 or 80% re-profiled/finished/engraved]

  • Grip: A1, A2, ERGO Original
  • Stock: Originally issued with A1 stocks, both solid D and trapdoor E types; as A1 stocks dwindled, A2 were used; ModH rifles rebuilt with Ace SOCOM stocks
  • Small parts: Standard M16A1 parts

  • Iron sights: (apparently PRI were supplied but never used)

In the Wild
Naturally, once these rifles were issued to units, operators and even Marines used various non-issued parts. Here is a short summary of what has been seen:

Early SPR/Mod0:
Both Leupold 3.5-10x40mm and 3-9x36mm scopes have been used. Many have had carbine stocks like the old CAR-style, enhanced M4, SOPMOD Gen I, or even the Tactical DuoStock swapped on.

Mod1:
One 3rd SFG-issued rifle pictured with SSgt Robert J. Miller (MoH recipient) used an A.R.M.S #36 S-EX 5.56mm rail, and a Leupold M3X 10x fixed-power scope, possibly pulled from an M-24 or SR-25 rifle. Another has been seen with a Magpul PRS, LaRue mount, and a Premier Reticles 3-15x used by an AMU shooter, and a similar rifle was pictured on a FOB in a very posed-looking photo. Further, a USMC-issued Mod1 was seen using #22 Medium rings instead of High rings, and a LaRue mount has been spotted as well. Grips have varied from the usual A1, A2, and ERGO, and at least one Magpul MIAD has been used. As with the Mod0s, carbine stocks like the SOPMOD and M4 have been used on Mod1s.

ModH:
The Mod "Holland" was already a small-batch configuration, but even as soon as they were issued to 5th SFG units, some Ace SOCOM stocks were replaced with Magpul ACS and CTR stocks. Optics are basically anything existing in the unit's inventory, from S&B ShortDots still in the system, the 3-9x and 3.5-10x Leupold scopes from earlier Mod0s, and there's even a photo of an ELCAN on a Mod1 floating around. No non-magnified optics like EOTechs or regular Aimpoint M2/M4s, but Micros have been seen on offset mounts. Backup iron sights, as a whole, were almost entirely left unmounted. Grips were again the same usual selection.

Parts Alternatives for Clone Building
Many parts are rare, expensive, and/or both. Despite this, there are some alternatives to a 100% pure clone that will still provide the same visual look and performance. While not a museum-grade clone, most would be hard-pressed to discern the difference. Just know there are those of us out there that will haze and peer-pressure you into further moving your build towards a true clone.

Barrel:
Popular options are the White Oak Armament SPR barrel (rifle gas), BCM's SPR barrel, Rainier's Match and Ultramatch offerings (ensure it's the SPR contour with 12th Model profile), Ballistic Advantage's SPR barrel. Compass Lake Engineering can also spin a Mk12 profiled barrel with a Criterion chrome-lined blank, or even a Krieger, which was one of the original contenders for the program. The DPMS Mk12 barrels are NOT properly profiled for a clone.

Optics & Rings:
In the case of the Leupold 3-9x or 3.5-10x, it's generally okay to go for a non-illuminated version of either, sometimes with M1 or other turrets and reticles. As far as the NightForce scope, the 2.5-10x24mm is not generally released to the public anymore (with one recent exception through Sniper's Hide), so many use the 32mm or even 42mm versions with the #22 High rings. As for the rings, any of the recent produced A.R.M.S. #22s with the lever-stop humps are functionally the same, the desire for non-lever-stops is purely aesthetic when going for the most authentic look. As LaRue LT-104s have been seen in use, it is justifiable to use one depending on whether you have a specific rifle you want to copy, or even just if you absolutely cannot acquire #22 High rings.

A.R.M.S. #38 SWAN Sleeve:
The #38 family of sleeves are no longer available. Finding them secondhand usually cost $250-$300 easy, more for rarer early variants. Fortunately, PRi's copies of the sleeves look and function almost identically, with minor visual differences. PRi and other builders supply these currently for complete Mod0 builds.

FSB:
While the set-screw version of PRi's FSB is spec, most use the cross-bolt, clamp-style version. They are extremely robust, and when aligned and torqued, have been shown to hold strong enough that you'll probably shear your barrel extension pin or upper before it budges. This is mainly how Mod0 uppers are supplied by most vendors, including PRi themselves.

Suppressor, Brake/Collar:
Diverging from the OPS Inc. or AEM brake and collar will get you MAJOR flak. Trust me, I've been running an AAC SPR/M4 for years now and it took a LONG time to not get clubbed every time I posted it. The Allen Engineering AEM5 is basically the current production of the OPS Inc. 12th Model, as they were originally made by Ron Allen and his team in the first place. Only minor differences separate original OPS Inc. cans from AE cans, and these are only obvious to trained eyes.

As far as the rest, you can swap Colt parts out for any other .mil-spec parts, like BCM, DD, CMT, etc. Any billet uppers/lowers, funky BCG coatings, extended bolt releases, etc. are extremely frowned upon. Remember, once you start going down the path of building a "better" rifle rather than what was spec, you're quickly beyond clone territory and would have been better off building a custom 16" or 20" rifle. Cloning is generally viewed as all-in or not at all.

Thanks for the chuckle.

On a serious note, we should really look into doing a NW shoot.
Rock Lake Range would be awesome. If that doesn't pan out, I know a few good places in eastern wa that we could shoot out past 1k.
If anyone is interested PM me and we can coordinate this rodeo.

BTW thanks for working so hard on those labels. They turned out great. Pm coming your way.

Too bad there aren't more mk12s here in the central Midwest, a shoot sounds like a blast! I usually go to NC for business, but wrong time of year for that shoot.

Will do, I'm thinking sometime late winter / early spring. I've got SDMF_Rebel, BSOG1, Davey_Sickboy, and Dobs013 written down (anyone else wants to go just let me know). I'll contact everyone when the date gets closer so we don't clutter up the thread.

well, maybe we'll have to start a texas mk12 shoot.  since we da biggest.

also, just got this ordered.  looks like a mod 1?  judging based on the rail marks on the bottom of the foam.

Lancecriminal mentioned best of the west but that place gets really crowded these days. I'm checking with some guys I know that have some land around here to see if they are open to having something. I have 35 acres near Colorado Springs that is just open flat land. If I measured right there is room for a 600yd range but that's an 11-12 hour drive. Maybe a 3 day weekend thing.

I've got everybody contacted and paid who was on my original list EXCEPT for these people:

Ray9101
BSOG1
Lonewolfgun

These three guys I will try to contact over the weekend. I have 5 alternates so I will get more printed.

There are a couple other models of that scope that are identical except the markings your going to paint over and the battery cap lanyard. You can buy the mk12 mod 1 turret seperate for 36.00 if you want a turret that says mk12

I would also be in for a Northwest shoot. The range I'm joining has a range out to 500yd. Guests are welcome.
But I'm also down for the drive as well. Would be fun to meet some of the mk12 fellas.

So.. long time lurker here; first time poster. Jumped into my next project with purchase of HCS mk12 MOD1 upper. Im going for a close clone but definitely not perfect. Im really looking at night force 2.5-10 X32 after much fretting over optics but Im still not sure if I want Mil Dot or Mil R reticle. Im planning on getting Mil/Mil model as I want to use this gun for precision rifle class and willing to sacrifice correctness for usability. What reticle would you pick and why?

I' pick the one you know how to use.  Of all the clone correctness the reticle is one of those things that no one else is going to know

So does nobody actually have a correct Mod 0 with the TS30, A1 lower, and set screw FSB?


I'd really like to do a manual for you Gen III owners but I can't very well do that without someone working with me on pics. Feedback is good so far on the early SPR/Mod 0 OM so I think maybe it should go to Samson soon for a print run.




Also stop putting 3.5-10s on late Mod 0s, it's bad and you should feel bad.

I just got my TS30A2 from optics planet.  It had the mk262 caps and all.  Just make sure you pick the right PN.  Should be 112633.

That price has been quoted often, but I think it's just an old price - recently I think it been stated the Turret is about $80-90 or thereabouts.

So I may be ashamed of this and may have sold these parts to a member here. I can't find any record.....
I built this upper in '06 or '07 and never shot long range then. I built it because it looked cool and Americas Army (I'd doubtanyone remembers that game) After a short time I parted it out and went upon my way. The only record I have of the upper is theset two pics from my Facebook. If anyone here has these parts I'd love to hear it and where they've been. I have my mod1 now but would love to do another mod 0 with peq rail someday.

Thanks, Tom.

I very much remember that game. In fact I think ARMA 2 is possibly the first time I saw a Mk12 to be honest...

I've got everybody contacted and paid who was on my original list EXCEPT for these people:

Ray9101
BSOG1
Lonewolfgun

These three guys I will try to contact over the weekend. I have 5 alternates so I will get more printed.

I won't lie, America's Army is why I fell in love with the Mod 0.   So many VIP kills with it on the hospital map.

Where can you get the MK12 turret for $36?

Call Leupold. Part number112635. 36.00 and some change. It's the standard turret on 112633(TS30A2)
I bought 2 of them less than 6 months ago for 36 bucks each. If the price went up in the last few months I can not speak to that. I think I bought them in August or September

Lancecriminal I have an early mod 0 with a TS30 (3-9x36) and wheel fsgb. Do you need pictures? Oops..I don't have the A1 lower on it yet. Still working on the anodizing problem for my braceman lowers. They are A1 but not finished. I go pick up my AEM5's tomorrow finally.

No I need the Gen III. The Early SPR is taken care of, Wheelman had a perfect pic for that.

What I'm looking for are the late rifles with the correct parts, but almost everyone has clamp FSBs.

This is the dangerous time of the night...I'm feeling good after some scotch and roaming the internet to buy gun parts. haha

Who has the best prices on the straight 20 round mags? Not sure if there is a specific model that's preferred/good quality and for a decent price.

I was thinking Colt's for $20
http://www.armsunlimited.com/Colt-AR15-M16-M4-20-round-USGI-Aluminum-Magazine-p/sp62103.htm

Or Brownell's for $12
http://www.brownells.com/magazines/rifle-magazines/magazines/ar-15-magazine-ss-223-5-56-prod71748.aspx


I've always used Colt USGI mags in the past...just curious if Brownells were a good value.
