About Real GAU-5/A XM177E1 COLT M610

The GAU-5/A, XM177E1, and Colt Model 610 are all designations for the same historic weapon: a compact, short-barreled carbine developed from the M16 rifle for U.S. forces during the Vietnam War. Often called the "Commando," it was created to fulfill an urgent need for a more portable, automatic weapon for helicopter crews, vehicle drivers, officers, and special operations troops like the Green Berets and Navy SEALs.
Its key features were a drastically shortened 10-inch barrel and a pioneering telescoping stock, making it far handier in close quarters and when entering or exiting vehicles than the full-length M16. The major challenge was the weapon's deafening blast and massive muzzle flash from such a short barrel. Engineers addressed this with a unique long, tubular "moderator" (a combination flash hider and sound moderator) that became its visual signature.
The different names indicate which branch used it: XM177E1 was the U.S. Army's experimental designation, while the U.S. Air Force called its version the GAU-5/A. Colt Model 610 was the manufacturer's commercial model number. It proved effective in combat, most famously during the daring 1970 Son Tay Prison raid. Technologically, it is the direct linear ancestor of today's M4 carbine, cementing its legacy as the foundational compact rifle of the AR-15 platform.

About Cybergun GAU-5/A XM177E1 COLT M610  GBB Airsoft Rifle (CGS System)

CYMA has introduced this classic rifle under Cybergun license, a model that emerged in the post-Vietnam War era as a transitional firearm between the M16 and the M4. More compact than the M16, it was designed for rapid movement in dense jungle terrain. It features an extended muzzle brake, which on the original firearm significantly reduced muzzle flash and helped conceal the shooter's position in wooded areas. Mass-produced after the Vietnam War, it saw extensive service with U.S. forces. Recognizing its unique historical significance, CYMA has recreated this replica of the GAU-5/A XM177E1 COLT M610, a weapon that marks an important milestone in firearms history.
This Cybergun GAU-5/A XM177E1 COLT M610 GBB Airsoft Rifle utilizes the CGS system and is constructed with a metal lower receiver bearing realistic engraved "COLT AR-15" markings, along with a metal upper receiver that incorporates a carry handle and rear sight. It is equipped with a 235mm metal outer barrel, a sturdy 112mm steel muzzle brake, and a 185mm polymer handguard capped with metal. The rifle also features a polymer pistol grip, a polymer stock attached with a metal two-position stock pipe, and a steel gas magazine with a 20-round capacity. Additional metal components include the steel trigger and trigger guard, metal charging handle, steel sling loop, bolt catch, front sight, magazine release, and dust cover, all contributing to its authentic feel and durability.
The airsoft rifle operates on a gas-powered CGS system, which is based on the Marui MWS design, offering very similar performance and allowing for compatibility with MWS internal upgrade parts. It provides stable and consistent shooting with high accuracy, representing excellent value for its performance level.
This meticulously crafted replica is an ideal piece for firearms enthusiasts and collectors, while its robust performance and reliable design also make it fully suitable for practical use in airsoft wargames and competitions.
