Golden Eagle M4A1 Gas Blowback Rifle (Metal – Black – MC6604M)
The Golden Eagle M4A1 (MC6604M) is a gas blowback airsoft rifle (GBBR) with metal construction, as listed. This listing is the black version. Gas blowback rifles cycle a bolt carrier with every shot, giving a recoil and sound that electric rifles cannot match.
Golden Eagle is a Chinese manufacturer offering a wide range of airsoft rifles, shotguns and gas blowback rifles at accessible prices. Its M4-family gas rifles bring the experience of a gas blowback rifle within reach of more players. The M4A1 is the classic carbine configuration, distinct from the railed RIS CQB model, and the metal build gives it a solid feel.
How a gas blowback rifle works
Instead of a battery and gearbox, a GBBR stores gas in each magazine. When you pull the trigger, the gas fires the BB and drives the bolt carrier back, which resets the mechanism and gives a felt recoil before the bolt returns and chambers the next round. The result is a rifle that feels lively and realistic to shoot, and many players find it the most enjoyable kind of airsoft rifle to use.
The trade-offs are gas consumption and temperature. Each magazine carries its own gas, so performance falls as the magazine cools during rapid fire and on cold days. Keep spare magazines warm, use measured bursts and allow a moment between shots in winter.
Build and handling
The rifle is listed with metal construction. It follows the familiar M4 family layout, so the controls fall naturally to hand and it works with the wide range of external M4 accessories, from slings and optics to lights and grips. Please check the product photos for the exact handguard, stock and sights on this version.
Getting the best from it
Use the gas type recommended in the manual, fill magazines carefully without overfilling, and let them rest for a moment after filling. Set the hop-up for your BB weight, and have the rifle chronographed at your site before play, as gas rifles can vary with temperature.

Use magazines made for Golden Eagle M4-family gas blowback rifles; gas rifle magazines are not interchangeable between brands, and AEG magazines will not work, so please check with us before buying spares. External M4 accessories such as rail-mounted optics and lights fit as normal. Use the gas type recommended in the manual.
Care and maintenance
Lubricate the magazine fill valve and seals with silicone oil every few fills, store magazines with a little gas in them, and never overfill. Gas blowback rifles cool down quickly in cold weather, so keep spare magazines warm and allow time between bursts.
Wipe the bolt carrier and other moving parts with a thin film of silicone oil, clean the inner barrel with a rod and patch, and use good quality seamless 6mm BBs. Keep the rifle and magazines away from heat and direct sunlight, and store them somewhere dry.
Who is it for?
Players who want the realism and recoil of a gas blowback rifle in the M4 family, and anyone who enjoys a hands-on, mechanical rifle.
Please note: Gas and BBs are not listed as included. Always wear suitable eye and face protection when using airsoft replicas, and check your site’s rules and power limits before play.
