A Gunfighter’s Replica: BCM Mk12 Mod 0 — Full Review

It is kind of strange to be looking at a replica gun for the war I was served in, but it’s pretty cool too. BCM has made a series of authentic looking SPR rifles. The test rifle they sent GunsAmerica is the BCM Mk12 Mod 0.A Gunfighter's Replica: BCM Mk12 Mod 0 — Full Review

A Little Background … the SPR & the SR-25

A Gunfighter's Replica: BCM Mk12 Mod 0 — Full Review

The BCM Mk12 Mod 0 incorporates a PRI front flip-up iron sight.

The SPR program started as an upper receiver to fill the gap between a full SR-25 semiautomatic sniper rifle in 7.62x51mm and the standard 14½ inch M4. SPR originally stood for special purpose receiver; however, as the SPR eventually came to service as a full weapon system — not just an upper — it stands for special purpose rifle. It is designated the Mk12 in the typical way that U.S. Navy naming conventions make zero sense, yet Naval Surface Warfare Center Crane is where most of the SOCOM toys originate for the U.S. military. The Mk13 is a bolt-action rifle chambered in .300 Win. Mag. — go figure. This system is utilized by the U.S. Army and Navy. The concept was originally proposed by the current president of Armalite Mark Westrom, who was working for Rock Island Arsenal at the time.

The SPR has a long and storied history of Special Operations Forces (SOF). They have been used in every theater of the Global War on Terrorism (GWOT) by our ninjas and with outstanding success. The relatively light weight of a 5.56-chambered rifle and ammunition combined with the velocity and reach of an 18-inch barrel made them popular both in urban combat in places like Baghdad and the mountains of Afghanistan. The SPR is supposed to serve a light sniper/designated marksman role.

BCM’s Mk12 Mod 0 features a PRI free-floated handguard, an A.R.M. flip-up rear iron sight and the receivers are machined from Mil-Spec Carpenter No. 158 steel.

Just a few weeks before this review, some of the boys from Fort Bragg called me and we discussed the idea of the SPR. Amongst the eight of us in the discussion, it was almost an even split between who would choose the SPR or the SR-25 for urban combat. With our wealth of combat experience, using a variety of weapons across a variety of times and places, we couldn’t reach a consensus on which was better. I’d choose the 7.62. (Or at least 27-year-old me would. I was sprier 10 years and a lot of injuries ago.) However, I cannot discount my friends that selected the 5.56. There are a lot of valid arguments in its favor, and no one present had any tales of bad guys walking off multiple hits of 77-grain Black Hill projectiles. In smaller cartridges, velocity kills. And 18 inches is near perfect for achieving that velocity.

BCM’s Mk12 Mod 0 Ergonomics

A Gunfighter's Replica: BCM Mk12 Mod 0 — Full Review

BCM deviated from the original but adding a VLTOR collapsible buttstock.

The original barrels were custom barrels from Douglas Barrels, Inc. and were renowned for the accuracy they delivered. The BCM Mod 0 rifle we were sent incorporates an 18-inch BCM stainless steel 410 barrel with an ion bonded black DLC coating. The original muzzlebrake was unique and designed to accept the Ops Inc. 12th model. BCM offers several different options of muzzlebrakes. The handguard is a Precision Reflex, Inc. (PRI) design, and was one of the first free-floated handguards used by the military. The front sight is also PRI. It was an early folding model.

Not to stand on my soapboxox and yell about you damn kids, but to really appreciate this rifle consider how the world stood in 2002. There wasn’t much choice in equipment, and the idea of folding anything was unique. It hadn’t been that long since we had Picatinny rails on our rifles. Before, most high-speed guys in the universe literally had a mag-lite held on by hose clamps. The SPR handguard and folding sights might as well have been space lasers from Mars. The rear sight on our rifle was the A.R.M.S, Inc.  No. 40 flip-up, which became the standard on every SOF rifle in the inventory.

The author’s test rifle came with a BCM Mk12 compensator. BCM offers several options for shooters to choose from.

The buttstock is a deviation by BCM on this rifle, but still period plausible. The original SPR came with an A2 style buttstock, but most end users swapped it for another. BCM ships this one with a VLTOR, which was a favorite of SOF around the time the SPR was being issued. I ran that one for quite a while on my M4. The pistol grip is pure BCM. There were a variety of options that would have seen service on the SPR, depending on taste. They ranged from a DPMS panther style to a Tango Down or Hogue rubber pistol grip. The BCM version is comfortable and fits in with the style of the rifle.

The trigger will be one feature that shooters will be happy BCM didn’t go authentic. BCM ships with nickel boron coated trigger, which is pretty smooth for a factory job. You might want to upgrade later, but it beats the pants off of the normal parts bin.

For optics, there were a variety of options that would have been legit. I finally decided to go with a Leupold 3.5-10 LR M3. This may have been what came on the SPR from Crane as there always a gaggle of them floating around the team room. I called Leupold and was amazed to find they still make them in their custom shop. This scope was pretty high speed for its time. And if you insist on authentic, it is still a good choice. It has some features we giggle about nowadays, but that wasn’t the case when the GWOT was fresh. It features a Mil-Dot reticle, MOA elevation and windage adjustments, and it is a second focal plane (SFP) scope. The glass was clear, and I had no trouble banging a target at 800 meters with this combo. After, I remembered how to adjust in MOA. There may or may not be a shot on video that was 15 feet over the target.

The author outfitted his Mk12 with a Leupold 3.5-10X LR M3 and was comfortably ringing steel at 800 meters.

Lasting Impressions

This rifle review was a fun trip down memory lane. If you are a collector or carried one of these in the war, I recommend it highly. Mine shot 1-inch groups at 100 meters with 77-grain Black Hills ammo, which is pretty legit for a 5.56 gun. The 77-grain Black Hills projectiles are authentic too. It was actually a Black Hills contract ammo build for the SPR. It’s absolutely a collector’s piece, but you can still get the work done with it if you need to. The handguard and iron sights might look ancient by our 2017 standard, but don’t forget: In this configuration, this rifle, has served many of our warriors well as they fight and continue to fight in the GWOT.

    I see why you used to go off on some of these chowder head comments.
    So many commenting” they wouldn’t take a bushmaster into combat”…all said by clowns who have never been in combat.
    Its not the weapon manufacturer that makes the weapon deadly, its the operator. All AR-15’s are made on CNC machines to milspec, and yes some use better steel. the better ones will go 25,000 rounds before they need new parts.. more rounds than any couch commando will ever shoot. even the average bushmaster or Anderson will go 15,000 rounds with no issues.
    A.co 3/505 2 combat tours.. 1 as a M249 gunner, the other as squad leader with a M203

    I have to chuckle when I read the comments regarding which AR one would take into harms’ way; My faves are the ones that go something like “I wouldn’t carry anything less than a Daniel or a Noveske or a super duper whatever costing $2,500.00 minimum”…………

    Then I saw the video interview with Chris “Tanto” Paronto where they asked him to describe the weapon he carried into combat the night of the Benghazi attack………

    Without blinking, he took out a $600 Bushmaster rifle he bought at Wally World and used it to hold off hundreds of our enemies that night.

  • Russ H. July 17, 2017, 5:20 pm

    Geez people, what\’s with all the shitty comments? It\’s a great copy of a MK12, which means it\’s a collectors rifle. It also means it is expensive – it\’s not an off the rack AR. Plus it shoots at least 1 MOA. If you don\’t want it don\’t buy it – no one cares how many sub-standard AR\’s you could buy instead – yes, we know. It\’s a COLLECTORS rifle.

    • L Dixon December 27, 2019, 10:32 am

      Well said Russ! There’s far too much of this ‘you could’ve bought this many of this type of AR for that price’ going on. I can bet that the majority that say this don’t shoot at all or aren’t possibly nowhere near an authority on anything…

  • Firejareen July 17, 2017, 1:26 pm

    So the MK12 was named after the Ops Inc 12th model suppressor it was mated to when it was issued. The MK12 was as custom as the military could get in the early GWOT years. These are not standard AR-15s by any means, they will out shoot any off the rack AR in any gun store. The issue trigger would have been a Knight’s Armament two-stage or a Geissele SSF two-stage, not a standard grade military trigger. They have documented hits on targets at over 700 yds. Marcus Latrell, from Lone Survivor, used the MK12 and was what he carried for Operation Red Wings when he was forced to deal with that fiasco. He shot and killed across a valley form a hide and the Taliban couldn’t find him. If you want a cheap AR then get one. If you want to ring steel at distance then build or buy a MK12

    “the receivers are machined from Mil-Spec Carpenter No. 158 steel.”
    Hahaha I seriously doubt that! It would be cool, though. A 14lb 5.56 AR? Sure!

    To the gentleman above to suggested buying multiple Bushmasters…*shudder*… wow.
    Have you shot (or even held) a Bushmaster in the past 5-7 years? The days of those being guns you’d want to take into harm’s way are LONG gone. You’d literally be better served with a DTI or other midlevel factory gun. It’s sad really.

    • joe July 17, 2017, 9:48 am

      What’s with all the snark? You don’t make mistakes? Must be nice.

  • Qhorse13 July 17, 2017, 8:17 am

    Looks just like the other 5000 AR’s out there on the market! I have Hohhot this was going to be something special. Headline fooled me!

  • Lloyd Dumas July 17, 2017, 8:13 am

    Too many $$$$.

  • Cyrus July 17, 2017, 7:13 am

    . . . you can buy 3 Bushmasters for less than the price of 1 of those!

    • steve July 17, 2017, 3:31 pm

      yea…i suppose you could. but why would you?

      • L Dixon December 27, 2019, 10:33 am

        Agreed Steve!

  • Daveius Maximus July 17, 2017, 6:01 am

    Another ar15…….. Yawn, can’t wait til it jams up in combat.

  • IYearn4nARnCali July 15, 2017, 4:12 pm

    Cool review, which rail is that on the rifle? Is it a PRI?
    I have the handguard and I’m thinking of doing an SPR project rifle.
