October 6, 2010

On Thursday, September ix, 2010, Defense Review visited Filly Defense LLC in Hartford, Connecticut to encounter, handle, photograph, videotape, and test-fire a gun I'd only heard about in excited whispers and hushful tones from professional contacts of mine, a ballistic specter that had already, sight unseen, excited the imaginations of all the tactical gun cognoscenti who were already aware of its existence. The very-short-notice invite had come the week before in the course of an email message from a high-ranking Colt Defence executive. The message was brusque and curtailed. It read: "David – Would you be interested in our flying you out here next Wednesday to see with us adjacent Thursday to see the CM901 and write an article on it?" My response was even shorter and more concise: "Certain! Admittedly."

The following week, afterwards moving some prior engagements effectually, I was on a plane on Sept. 8th flying out to experience the Colt Modular Carbine (CMC) Model CM901 modular, multi-quotient battle rifle/assault burglarize/carbine/SBR (Short Barreled Rifle) for myself. "Modular" and "multi-caliber" are really understatements, since the CM901 is, hands, down, the most versatile battle rifle/set on rifle we've ever seen in both respects. The heart of this versatility lies in the combination of the patent-awaiting AR (AR-10/AR-xv)-format "universal" multi-caliber lower receiver and conversion arrangement and Colt Defense'due south various AR operating systems and uppers, which allows the end-user to configure the gun in then many mission-specific means, information technology's well-nigh mind-boggling. The CM901 provides a truly sumptuous feast of versatility with regard to configuration options. Let's get right to the high points:

i) The Colt CM901 Modular Carbine is a select-fire AR (AR-x/AR-15)-platform weapon, so it will immediately wait, experience, handle, and shoot in a way that's immediately familiar to all military end-users, including general infantry personnel. It likewise benefits from the AR platform's at present legendary ergonomics/usernomics.

ii) The CM901 multi-caliber battle carbine tin can exist configured in any/every caliber between 7.62x51mm NATO (vii.62mm NATO)/.308 Win. and 5.56x45mm NATO (5.56mm NATO)/.223 Rem., including 6.8 SPC (6.8x43mm SPC) and 6.5 Grendel, depending on what U.S. military end-users crave. To switch from 7.62mm to 5.56mm, just push out the ii receiver pins, take the vii.62x51mm upper module off, slap the 5.56mm upper module on, button the ii receiver pins dorsum in, and you're practiced to go.

3) The CM901 universal lower receiver will accept whatsoever/all legacy MILSPEC 5.56mm NATO AR burglarize/carbine/SBR upper receivers already in the U.South. military inventory, including the, Colt M4/M4A1 Carbine fourteen.5″ AR carbine , M4 Commando eleven.5″ AR SBR, MK18/CQBR (Close Quarters Battle Receiver) 10.3″ AR SBR, and M16A3/A4 twenty″ DGI rifle uppers. The CM901 lower will likewise accept the Colt LE6940 16″ monolithic upper and Colt LE6920 xvi″ M4/M4A1 Carbine-blazon uppers. Thus, 5.56mm butt length is determined by any AR upper you want to use. Defense Review test-fired the Colt CM901 7.62mm upper sporting a 16″ barrel, simply information technology'south DR'southward understanding at present that 13″, 18″, and twenty″ barrels will as well be bachelor per client request (unconfirmed/unverified).

four) While the CM901 7.62mm upper receiver is a monolithic upper/track format with a directly gas impingement (DGI) operating organisation, the CM901 tin can utilize just about any 5.56mm burglarize/carbine/SBR operating system that Colt manufactures, including the Colt M4/M4A1 DGI system, Filly APC (Advanced Piston Carbine)articulating-link gas piston/op-rod (operating rod) organization, Colt AHC (Avant-garde Hybrid Carbine) DGI/piston-driven hybrid system, and Colt ACC-M (Advanced Colt Carbine-Monolithic) monolithic DGI upper. Defence Review does not yet know whether or not the CM901 lower can be configured to work with the Filly SCW (Sub-Compact Weapon) SBR upper, since the SCW utilizes a special brusque buffer organisation and buffer tube, which allows information technology to utilize a folding/telescoping buttstock.

5) The CM901 sports fully ambidextrous controls a.chiliad.a. "total ambi controls", including ambidextrous safety/selector switch, commodities catch hold-open up/release lever, and mag release button.

6) The CM901 when configured for .308 Win utilizes the MagPul 20LR 7.62 magazine. The weapon volition also accept the SR25/M100 7.62mm magazine. The weapon when configured for 5.56mm will accept all "MILSPEC" 5.56mm magazines.

seven) Existence an AR, the CM901 can utilize some aftermarket tactical AR rifle parts and accessories, like telescoping/retractable buttstocks, and trigger/hammer groups. Colt Defense had both Vltor IMOD and Vltor EMOD stocks for the CM901 image on hand, while I was there, only you tin stick a MagPul CTR (Compact/Blazon Restricted) stock or LMT SOPMOD/SOCOM/Crane NSW stock on in that location, if you'd like.Editor's Note: Defence Review likes all 3 buttstocks (Vltor IMOD, MagPul CTR, and LMT SOPMOD).

The CM901 will provide the military end-user with a select-fire AR platform weapon in whatsoever caliber between 5.56mm and 7.62x51mm, allowing him to use whatever "MILSPEC" 5.56mm AR upper receiver he wants, also allowing him to use any 5.56mm AR operating system Colt Defense offers, and lets him choose his barrel length. Colt Defense is even in the process of developing their articulating link piston and DGI/piston hybrid operating systems for the seven.62x51mm CM901 upper receiver module.

The CM901 Upper Receiver Modularity concept: simply change out your upper receiver assembly to re-configure the weapon for the mission, without having to re-zilch your weapon and you're set up to go. Examples of upper receiver configurations users could have are:

– MK18/M4 CQBR x" upper equipped with a EOTech EXPS3-two HWS (Holographic Weapon Sight), Aimpoint Micro T-1, Aimpoint CompM4, or FERFRANS FAS (Fast Acquisition Sight) combat optic.,
– Colt M4/M4A1 Carbine fourteen.5" upper equipped with a ELCAN SpecterDR 1-4x or Trijicon ACOG (Avant-garde Combat Optical Gunsight).,
– MK12 Mod 0/1 SPR (Special Purpose Rifle) 18" upper equipped with a Schmidt & Bender Short Dot Telescopic or Trijicon Accupoint Telescopic., and
– CM901 7.62mm carbine/rifle upper equipped with a Nightforce NXS 2.5-ten×32 Compact or Leupold Mark four three.five-10x40mm ER/T M5 Front end Focal Riflescope.

Military operators are already used to swapping out AR uppers with optics pre-mounted and nada'd. They like this organization, and they trust it–and it'south already boxing-proven.

Defense Review spoke with CTT Solutions/Grey Group Training tactical instructor, retired U.S. Army Special Forces (SF) assaulter/operator, and Defense Review contributor Mike Pannone a few days ago about the CM901, and asked him his opinion about information technology vs. the FN SCAR weapons, assuming FN fully develops the SCAR "mutual receiver". Mike prefers the AR rifle organisation'south upper receiver modularity to the FN SCAR quick-change barrel system/"trigger module" philharmonic, and he had this to say (or, in this case, write) about a butt change/lower receiver module system (SCAR) vs. modular upper receiver change system (CM901):

People often confuse quick change with modularity when it comes to weapons systems. They are in fact completely different concepts in well-nigh every regard.
For the sake of discussion let's talk about quick-change barrels vs. modular upper receivers (AR/K-4 blazon platform).

First, the definition: quick-change means that parts of an existing weapons system can be replaced with the same replacement function (call up fixture point, non cosmetics or barrel length) in a relatively rapid manner with minimal or no tools. I emphasize "relatively" considering that is subject to end user specifications. Quick change tin be v minutes (LMT MRP barrel) or ten seconds (M249 barrel), and so it'south relative.

Modular means a family of parts and accessories will fit on any system that uses a standardized mounting platform. The AR family of weapons and the [Mil-Std-1913] Picatinny rail are the best example of modularity. The AR system, besides, is in its two primary components a modular system; button two pins and you can swap complete uppers, even between nigh all manufacturers.

Modularity by default is quick-modify only quick modify is not always modular.

I challenged Mr. Pannone with the following:

Mike,

Couldn't FNH argue that, in one case they have a "mutual receiver" (upper receiver) for 7.62 and five.56, their quick-change barrel organization and swappable trigger module/lower receiver module together make a modular organization?

Not the barrel by itself, simply the combination of the two. Just looking at every angle.

To which he countered with:

It will make them quick change within their organisation as well equally limited modularity inside the arrangement. Information technology is not modular in the bigger sense that in that location are many different vendors offering a bill of fare of replacement parts that are swappable. By the alphabetic character f the definition it would be modular, but [only] in the nearly limited sense, and only within their own manufacturing capacities, since no companies that I know of make replacement parts [for the SCAR weapons].

If you extrapolate it out, everything, in a sense, is modular in its own right.

In industrial pattern, modularity refers to an technology technique that builds larger systems by combining smaller subsystems.

Defence force Review contributor Chen Lee (a.k.a. "SMGLee) commented on the combat advantages/attributes of the Colt CM901 modular/multi-caliber weapons platform:

The adequacy provided past the CM901 gives an boosted dimension to [war machine] operators. No longer will a warfighter get stuck running a DMR [Designated Marksman Rifle] in an urban warfare environment, where the platform might not suit that particular moment of combat. Those days of a sniper conveying a rifle in a haversack, while fighting his way into position with a handier weapon, are a thing of the by with the advent of the CM901. Today, a warfighter can have his cake and eat it besides, fighting with a MK18 Mod1 on a CM901 lower while the .308-based CM901 is carried in a padded backpack. When the occasion arises, the operator can change out the v.56mm CQB-R and instantly go to a .308 rifle [CM901 seven.62mm upper] for the counter sniper role, or whatever situation that requires a designated marksman.

The only downfall I see would be the logistics of keeping two split calibers within one shooter'due south loadout. But with 5.56 [mags] carried on the belong, the .308 magazines could exist carried in a pack since the shooter is already dropping the backpack in gild to access the .308 platform.

The CM901 volition provide added fighting capability to [military] operators in today's ever-irresolute battleground.

Colt Defense Executive Vice President (EVP) and Principal Operating Officeholder (COO) Maj. Gen. James R. Battaglini USMC (Ret.) issued the post-obit argument on the CM901 to DefenseReview:

Colt Defense's approach to weapon design is to determine the warfighter requirement and then to provide a solution. Our principal customer is the The states military, not the commercial market. Colt's focus is the warfighter; our largest client is the The states Ground forces; and, we design and manufacture to strict war machine specifications. Despite efforts past individuals to deride the M4 Carbine in order to promote other products, many which are commercial off the shelf, the US Army and Soldiers take been more than than satisfied with the performance of the M4 Carbine in combat over the past vii years in Iraq.

As Us forces have at present transitioned their focus of try to the war in Afghanistan and its gainsay conditions and threat, warfighters are more determined in seeking varying calibers and a college level of modularity in their private weapons to meet mission needs. With the performance of the M4 Carbine and M16 Rifle every bit the proven standard for the five.56mm private weapon, Colt'due south approach has been to provide a simple and toll effective solution to come across evolving warfighter demands.

Colt's CM901 is designed as a multi-caliber, modular adequacy with one lower receiver configurable to different calibers and butt lengths for different missions. With its universal lower receiver based on the 7.62 mm round and the ergonomics of the M4 and M16, the lower receiver is likewise compatible with the upper receivers and bolt carrier assemblies of all existing Colt weapons in the military inventory and its newly developed weapons and alternative operating systems from vii.62mm to 5.56mm. Colt has kept its solution elementary, operationally and cost effective, and easily adaptable for the warfighter and the support base.

Examination-Firing Session

While Defense Review was at Colt Defense LLC, we had the opportunity to fire the CM901 in both the seven.62x51mm and 5.56mm configurations on both semi-auto and full-automobile at Filly'south indoor test range. Colt Product Requirements Manager Chuck Olsen and I put a few hundred rounds down range betwixt u.s., without experiencing any malfunctions. Chuck shot with a bit more than abandon than I did, as I was concerned virtually putting bullet holes in the walls and ceiling, especially while firing full-automobile strings. The exam CM901 7.62mm upper and universal lower being prototypes, I'd expected the weapon to hiccup a little fleck during the firing examination, simply nope, it didn't. It ran similar a charm. The CM901 universal lower receiver/caliber conversion system works. Information technology really works. It works like gangbusters–at least nether range weather condition. Permit's confront it, test firing a weapon organisation at a clean, dry out range for merely a few hundred rounds isn't exactly a proper test of a armed forces small arm. Firearms designed specifically for military combat must prove reliable, durable, and accurate under agin gainsay conditions at loftier round count. They have to be tested for tens or even hundreds of thousands of rounds in mud, sand, rain, snowfall, dirt, you proper noun it, and keep going blindside…every time. DR didn't have the opportunity to examination the CM901'due south accuracy in either quotient configuration, but information technology's an AR, and ARs are famously accurate, assuming they're congenital right.

We only test-fired the CM901 with DGI (directly gas impingement) operating systems in 7.62mm and 5.56mm configurations. Information technology should perchance be noted that the LMT .308 MWS (Modular Weapons System) DGI 7.62mm battle rifle/marksman rifle recently vanquish out the gas piston/op-rod-driven HK417 and SCAR-H rifles to win a British Regular army contract. The British military machine has designated information technology the L129A1 burglarize/carbine. It's DefenseReview's theory that direct-gas-impingement (select-fire and semi-auto-only) rifles chambered in 7.62mm NATO/.308 Win. may really enjoy a durability and accuracy reward over gas piston/op-rod (operating rod) seven.62mm rifles, due DGI's lack of straight mechanical impact on the gas key/commodities carrier key/strike plate/tombstone and lack of a relatively heavy mechanical reciprocating mechanism (piston/op-rod) higher up the bore line. It'southward simply a theory at this bespeak, though.

Nosotros didn't test the CM901 for accuracy, but it's an AR, and it'south made by Colt Defence. We'd similar to perform an accuracy and reliability exam on an outdoor range, as a follow-up, at some point.

Whether or non the Colt Modular Carbine Model CM901 ends upwards being adopted past the military will depend on two things: 1) Colt developing information technology successfully and 2) the U.S. military machine small arms procurement folks preferring it to other weapon systems being evaluated. If Colt is successful though, the U.S. armed forces volition accept a second modern 7.62mm battle rifle/carbine/SBR option at their disposal, in AR format. In Defense Review's stance, that'southward a prissy choice to have. The question is, will civilian tactical shooters become the same selection? Volition Colt make the CM901 available to the civilian tactical shooting sector of the commercial market? Defense Review certainly hopes so. They'd better.

It'southward DR's opinion that if the the Filly CM901 ends upwardly meeting (or exceeding) all U.S. armed forces requirements, it represents the virtually important evolution in tactical AR rifles in, well…the history of ARs! With the CM901 modular/multi-quotient weapons system, Filly has essentially taken the armed services/tactical AR weapons platform taken to its ultimate logical conclusion, the ultimate evolution of the AR platform, if yous will—and we want one. We'll settle for the semi-car-merely version.

But what do you think? We're interested in our readers' thoughts and perspectives, so please feel free to comment, below.

Colt Modular Carbine (CMC) Model CM901

General Description:

The Colt Modular Carbine (CMC) Colt Model (CM901) is a User-level, mission configured, lightweight modular, multi-caliber, weapon arrangement. The system utilizes a jumpsuit upper receiver and is a multi-caliber, multi-operating system carbine/burglarize; it is magazine fed and capable of firing in both automatic and semi-automated modes. Utilizing a revolutionary new lower receiver and bolt carrier design the CM901 provides unmatched modularity in carbine and rifle blueprint, assuasive the warfighter to quickly reconfigure the weapon system to see multiple mission requirements.

Specifications:

The Colt CM901 tin can change calibers from five.56mm up to and including 7.62 ten 51mm NATO, past changing the upper receiver group. Past simply disengaging the takedown and pivot pins (No Tools, Gunsmith, or Gauges Required), the user tin apace change from a v.56mm Shut Quarters Battle (CQB) short barrel configuration to a full length 7.62 x 51mm Extended Range Carbine (ERC) configuration in seconds without the need to re-aught mounted sights. The CMC weapon organization is the ONLY SYSTEM to offer this user-level truly modular configuration capability. The CMC organisation all merely eliminates disquisitional mission time loss and fundamental personnel requirements to execute weapon configuration changes. This self-independent blueprint concept protects disquisitional components of the operating system and provides uninterrupted operability in all environments. The CMC is the ONLY "Single Serial Number Weapon Arrangement" that tin can exist reconfigured, at the commander'south discretion, into multiple carbine/quotient configurations without special tools. This same modular capability not merely applies to the caliber, but also to the operating system, which can exist configured for gas impingement, piston (Colt APC), or hybrid gas/piston (Filly AHC) operating systems. All of these modular attributes are at present bachelor at the unit of measurement level without sacrificing the boxing proven ergonomics and reliability warfighters have come to expect from Colt Defence LLC products.
