Colt 610/XM177E2 GBBR Replica CGS - Black [EMG]

The Colt XM177E2 replica from the CGS Vietnam series was developed by CYMA, T8 (SP System), and Taiwangun as a faithful recreation of one of the most recognizable rifles used during the Vietnam War. Equipped with the CYMA CGS system, full Colt Industries licensing, and TM MWS parts compatibility, the model combines historical styling with modern GBBR airsoft technology.

Brief history

The original XM177E2 was a compact variant of the M16 rifle designed for special operations units, particularly MACV-SOG. Production of this model was relatively limited, making it one of the more distinctive firearms associated with the Vietnam War era.

Its shortened configuration allowed for easier handling in confined spaces and during patrol operations in dense jungle environments.

Among the most recognizable features of the platform were its short barrel, distinctive flash moderator, and 2-position stock. These elements reduced the overall length of the weapon while retaining the effectiveness of the AR-15 platform.

Construction and design

The replica faithfully reproduces the defining features of the XM177E2, including its compact profile, flash moderator with grenade ring, and 2-position stock. Its compact dimensions make it well suited for dynamic handling and operation in confined environments.

The design incorporates a full fence lower receiver, an upper receiver with forward assist, a front sight base without a bayonet lug, and a delta ring handguard retention system characteristic of later AR platform variants used during the Vietnam War.

The replica is primarily constructed from aluminum, while selected high-wear components are made from steel. Steel parts include the flash moderator, front sight base, bolt catch, magazine release, trigger, body pins, magazine, and buffer tube castle nut.

Another distinctive feature is the bolt carrier assembly finished in a graphite-gray-black color scheme, reflecting the appearance of later AR-15 platform variants.

Colt Industries license

The model is manufactured under an official Colt Industries license and features authentic markings based on the original firearm. The reproduced details and period-correct design elements give the replica a historically accurate appearance representative of rifles used during the later stages of the Vietnam War.

CYMA CGS system

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

To improve durability, the internal system incorporates steel components including the bolt carrier, hammer, and complete trigger assembly. The platform remains compatible with most standard TM MWS parts, providing extensive opportunities for upgrades and customization.

Ergonomics and handling

The compact layout, classic sighting system, and AR-style controls support intuitive handling and operation. The replica is an appealing option for collectors, historical reenactors, and users looking for a gas-powered replica inspired by the Vietnam War period.
