Cybergun Licensed Sig Sauer 556 RAS Full Metal Airsoft AEG Rifle

The Cybergun SIG 556 RAS is a beauty with a fully licensed full metal body (metal upper and lower receiver), enhanced full metal gearbox and high torque motor, TWO (x2) 400rd hi-cap magazines, and a heavy-duty ABS composite handguard/rails up front. This AEG is amazingly accurate with an AK47 length precision inner barrel, knocking out targets well beyond 150 feet! If you like using standard M4 type magazines, but don't want to conform with the masses, the unique and premium performance Sig 556 is the gun for you.


This SIG 556 features some of the most reliable and well built version three full metal gearboxes on the market. Paired with this incredibly reliable metal gearbox is a high torque motor, easily capable of pulling up to an M140 spring. This makes the AEG fully upgradable to become a DMR, without having to purchase an additional motor! The hop-up unit is similar to the G36 style hop-up units, and is easy to adjust. This patented hop-up unit precisely adjusts the trajectory of the BB, providing you with laser accurate shots. The precision inner barrel's length increases the overall effective range of the SIG 556, allowing you to shoot at sniper like distances. The SIG 556 AEG uses a stick type battery, included, which is easy to install in the hand guard. The Sig Sauer 556 AEG is a premium performing airsoft gun, that out-ranges most AEGs of the same size.

From the finish, power, and realism to the FULLY LICENSED laser-engraved trademarks on the body (along with small SiGARMS trademarks imprinted on various other places (including on the magazines, the pistol grip, and on the rear stock), we are thoroughly impressed with this rifle, and you will be too. With 0.20g BBs, FPS is measured at 360-410 FPS.

Ammo type: Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs. For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Battery Charger Recommendation: Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly). Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly,also automatically shut off once the battery is fully charged to avoid overcharged batteries.
