CYMA AM012 M4 RAS II CQBR Full Metal Gearbox Airsoft AEG Rifle - BLACK

The CYMA AM012 M4 RAS II CQBR AEG is designed to shoot field-legal muzzle velocity, outputting up to 360 FPS (w/ 0.20g BBs) on our chronograph. While FPS dials down compared to the CYMA AM005 and CM005, this field-legal variant can be played in most airsoft fields that enforce muzzle velocity. Constructed with mostly metal components, including the outer barrel, rail system and buffer tube, this M4 airsoft rifle is extremely rugged unlike polymer body airsoft guns, making it able to withstand high-impact BB contacts. However, CYMA designed the upper/lower receiver with high-density polymer to minimize its overall weight. Unlike other AR-type AEGs, this M4 airsoft rifle features a RAS II rail system with integrated riser rail for low-profile red/green dot sights. The CYMA M4 RAS II AM012 AEG also comes with a full metal front sight post that you can easily co-witness with most rifle scopes. When it comes to internals, this CYMA AM012 AEG features a reinforced Version 2 gearbox for reliability, ported cylinder for optimal air compression, and a 290x6.05mm inner barrel for optimal CQB length.

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.
