Description
Colt M4 RIS Gas Blowback Rifle (Cybergun – 180559)
The Colt M4 RIS Gas Blowback Rifle is an officially licensed Colt replica sold under the Cybergun licence, reference 180559. It combines the classic M4 carbine with a RIS (rail interface system) handguard and gas blowback operation, giving you a realistic, recoiling M4 with plenty of room for accessories.
Cybergun is a French company that holds licences from many famous firearms manufacturers and produces officially trademarked airsoft replicas, often built for it by established airsoft factories. Licensed replicas like this carry the correct manufacturer markings, which appeals to players and collectors who want an authentic-looking replica. For players who want the full M4 experience – working bolt, recoil and a realistic manual of arms – a gas blowback M4 is the natural choice.
How gas blowback works
In a gas blowback rifle, each shot uses gas from the magazine both to fire the BB and to drive the bolt carrier back, giving a sharp, realistic recoil impulse and a working bolt you can see and hear. The bolt typically locks back when the magazine is empty, just like the real rifle, and you release it to chamber the next round after a reload.
Gas blowback rifles appeal to players who value realism and a hands-on experience. They need a little more care than an AEG, and gas performance falls off in cold weather, but the feel of shooting one is hard to beat.
Design and handling
The RIS handguard gives you rails around the barrel for grips, lights, lasers and other accessories, while the M4 carbine layout keeps the controls where any M4 user expects them. It is a well-balanced, familiar platform that works well in woodland and CQB alike, and the gas system makes manipulations such as reloads and bolt releases feel like the real thing.
Getting set up
Fill the magazine with the gas recommended in the manual, load BBs, and you are ready to go. Start with 0.20g to 0.25g seamless BBs and adjust the hop-up for a flat flight. In colder weather, keep spare magazines warm in a pouch close to your body to maintain gas pressure.

Compatibility
Gas blowback rifles need magazines designed for their specific system; AEG M4 magazines will not work, and GBB magazines from other makers may not fit. Please check with us that spare magazines are made for this model. Use only airsoft-specific gas, never lighter fluid or butane. Rail accessories should match the rail type fitted.
Care and maintenance
Use only airsoft-specific gas of the type the manufacturer recommends; never lighter fluid or butane, which damage seals. Fill the magazines in short bursts with the valve upright, and put a drop of silicone oil on the fill valve and outlet seal now and then to keep the rubber supple.
Store magazines with a small amount of gas in them so the seals stay seated, and keep everything somewhere cool and dry. After a game, wipe the replica down, lightly oil the moving parts of the bolt and slide or bolt carrier rails as the manual describes, and run a cleaning rod through the inner barrel. Gas performance drops in cold weather, so keep spare magazines warm in a pouch on winter days.
Who is it for?
This rifle is for players who want a realistic, licensed Colt M4 with gas blowback recoil, and for M4 enthusiasts who enjoy the hands-on manual of arms of a gas rifle.
