Colt CAR-15 607 Lightning Series Gas Blowback Rifle (EMG/Cyma CGS - MWS - COLT.1011-LS)

A Piece of Special Forces History

Before the M4 CQBR and the Mk18, there was the Model 607. Introduced in 1965 as a compact submachine gun variant of the M16 for vehicle crews and elite units in Vietnam, it was the first AR-15 to utilize an adjustable stock. The EMG/Cyma CAR-15 607 perfectly captures this groundbreaking piece of firearms history. It features the highly unique, experimental 607 retractable buttstock, which cleverly resembles a shortened M16 fixed stock but utilizes a hidden two-position latch to extend the length of pull. Paired with a 10-inch barrel and shortened M16A1-style ribbed polymer handguards, it is an exceptionally compact and historically fascinating weapon.

Authentic Licensed Externals

To satisfy the most demanding historical re-enactors and collectors, this GBBR boasts stunning external build quality. The precision-cast aluminium alloy upper and lower receivers are flawlessly finished and bear deeply engraved, fully licensed Colt M16A1 trademarks. True to the era, the upper receiver features a fixed carry handle with an integrated M16A1 rear sight, no shell deflector, and no forward assist. The rifle is completed with an original A1-style slim profile pistol grip and a period-accurate 20-round short STANAG gas magazine.

Tokyo Marui MWS ZET System Compatibility

The beauty of the Cyma Gas System (CGS) lies under the hood. Engineered in collaboration with T8 (SP Systems), the internal architecture is fully cross-compatible with the legendary Tokyo Marui MWS gas blowback system. This gives you a massive tactical advantage. Not only does the rifle deliver incredible out-of-the-box reliability and a deeply satisfying recoil impulse, but it also opens the door to the largest aftermarket upgrade ecosystem in the GBBR world. You can effortlessly use standard TM-spec MWS magazines, and you have complete freedom to tune your hop-up, inner barrel, and fire control group using widely available MWS components.

"Lightning Series" Performance

What sets this specific model apart is its "Lightning Series" internal designation. To maximize the rifle's cyclic rate and gas efficiency, it is equipped with a specialized lightweight aluminium bolt carrier group. Because the bolt is significantly lighter than standard zinc-alloy bolts, it requires less gas pressure to cycle, resulting in an incredibly snappy trigger response, faster rapid-fire capabilities, and vastly improved performance in colder weather. To ensure the weapon can handle this blistering speed, the internal trigger mechanism, bolt catch, and front sight post are all constructed from heavy-duty steel for ultimate longevity.
