Colt 607/GX-5857 GBBr Replica CGS - Black [EMG]

The Colt CAR-15 Model 607 from the CGS Vietnam series was developed by CYMA, T8 (SP System), and Taiwangun as a faithful recreation of one of the earliest compact AR-15 variants introduced by Colt in the mid-1960s. Equipped with the CYMA CGS system, official Colt Industries licensing, and TM MWS parts compatibility, the replica combines historical styling with modern solutions found in contemporary GBBR platforms.

Brief history

The original Colt Model 607 was one of the first attempts to create a shortened version of the M16 rifle for users requiring a more compact firearm. The model was used by special operations personnel, including Navy SEALs, as well as soldiers operating in confined environments.

The Model 607 served as the foundation for later CAR-15 family carbines such as the XM177 and GAU-5/A.

Construction and design

The replica faithfully reproduces features characteristic of early AR-15 variants. It incorporates a partial fence lower receiver, an early square forged upper receiver with forward assist, and a slip ring handguard retention system, all typical of mid-1960s AR-platform rifles.

Another distinctive feature is the bolt carrier finished in a bright silver-chrome color, reflecting the appearance of early AR-15 designs.

The replica is equipped with the historic telescoping stock used on the first CAR-15 carbines. The design utilizes a metal stock guide cover that also serves as a shoulder support, making it one of the most recognizable features of the Colt Model 607.

The replica is primarily constructed from aluminum, while selected high-wear components are made from steel. Steel parts include the forged front sight base, bolt catch, magazine release, trigger, body pins, magazine, and stock guide assembly.

Colt Industries license

The model is manufactured under an official Colt Industries license and features authentic markings consistent with the original firearm. The reproduced design elements and period-correct details give the replica the historical character of the earliest compact CAR-15 variants.

CYMA CGS system

The replica utilizes the CYMA CGS (CYMA Gas System) developed in cooperation with T8 (SP System). The platform is based on solutions known from the TM MWS system and features an adjustable trigger mechanism that allows users to fine-tune operation.

To improve durability, steel internal components have been incorporated, including the bolt carrier, hammer, and complete trigger assembly. The system remains compatible with most standard TM MWS parts, allowing for further upgrades and customization.

Ergonomics and handling

Its compact dimensions, classic sighting system, and AR-style controls support intuitive operation. The model is an attractive option for collectors, historical reenactors, and users seeking a gas-powered replica inspired by the early development period of the CAR-15 platform.
