The CM901 (Colt Modular) weapons system is based on Colt's existing M16/M4 military designs. It shares the direct gas impingement operation, as well as much of the action, controls, and basic aesthetics with previous Colt rifle designs. The system's heart is a common lower receiver housing an enlarged magazine well that will accommodate larger caliber ammunition than NATO 5.56×45mm rounds, ambidextrous controls for the bolt release mechanism, magazine release, and fire selector/safety lever, trigger group, pistol grip, telescopic stock, and buffer tube. The system will accept a series of upper receiver assemblies that contain the respective action required to accommodate the various caliber rounds accepted by the weapon. A re-designed upper receiver firing standard 5.56mm ammunition will be produced in various barrel lengths, all having a monolithic design with a full-length top rail, and three auxiliary rails for mounting accessories, free-floating barrels, and front and rear flip-up sights standard, when not using upgraded optics.
Upper receivers will be available in several calibers and barrel lengths, as short as 270 millimetres (10.7 in) for the 5.56mm model. The lower receiver will also accept older mil-spec M16 or M16 upper receivers with an adapter. Receivers will be available that accept 5.56×45mm NATO NATO rounds, 6.8×43mm Remington SPC rounds, 7.62×39mm rounds, and 7.62×51mm NATO rounds. Each upper receiver has its own rail system, which allows scopes, or other optics to be pre-sighted for each configuration, and swapped quickly to perform different tasks.
The system can be anodized in a standard matte black finish, but has standard color options including Desert Brown, Digital Camouflage, and Vista Camouflage, which are applied during the anodizing process to prevent wear during use.
Colt released the LE901-16S to civilian buyers on July 20, 2012. Colt planned to release several variants of the CM901 system, with the civilian "LE901-16S" being the first. The civilian model will be available with all the same features and finishes as the planned Law Enforcement and Military models, but will ship stock with a semi-automatic lower receiver, and an upper receiver with a 410 millimetres (16.1 in) barrel chambered for .308 Winchester ammunition. The barrel will come with a Vortex Flash hider. This variant will also accept civilian AR-15 upper receivers of multiple barrel lengths, and includes a magazine well adapter to accommodate smaller AR-15 magazines.
Colt CK901 model
In June 2014 Colt Canada announced the new CK901 (Colt-Kalashnikov) in an interview with IHS Jane's at Eurosatory. It is a direct-impingement AR-AK hybrid chambered in 7.62x39mm that is similar to the KAC SR-47. The standard carbine has a 16-inch barrel, a monolithic picatinny rail along the upper receiver, a three-position accessory rail forend (sides and bottom), folding front sight, detachable rear sight, and ambidextrous controls. The carbine weighs in at 3.6 kg (7.9 lbs) without accessories and 4.5 kg (9.92 lbs.) with accessories (like a loaded magazine and sling). A Short-Barreled Rifle (SBR) version with a 13-inch barrel is also rumored to be in the works. It comes with polymer 30-round AK-style magazines manufactured by US-Palm, but it can supposedly feed from any AK-47 interface magazines.
The CK-901 was first sold to the Yemeni Republican Guard in 2014, but rumors say the order was cancelled or not fully fulfilled due to the Yemeni Civil War (March, 2015–present). Further contracts in the Middle East and the Gulf States are being sought. There is talk of a civilian model, but none have surfaced as yet.
Potentially, like the modular CM901, the CK-901 could be made to chamber the smaller-bore Soviet 5.45x39mm M-74 round. Much like the CM901 7.62 NATO / 5.56mm NATO rifle, it could be made to chamber the smaller-bore ammunition from a changed-out upper receiver. It would feed from AK-74-type magazines through an adapter block for the larger 7.62mm Soviet magazine well in the lower receiver.
The big problem for Colt Defense / Colt Canada when marketing the weapon is the same problem faced by the Russian arms industry. Why would a Middle-Eastern, Gulf-region, or Southwest-Asian nation spend money on a modern or improved version of the Kalashnikov system when there are massive stocks of the older system still in inventory, available on the market, or being produced in national factories by those very nations?
