CYMA Full Metal M4 CM005 RAS II CQBR Airsoft AEG Rifle - BLACK

If you liked the AM005, the CYMA CM005 M4 AEG is a versatile AEG with improved modularity. Constructed of full metal, including the receivers, outer barrel and rail system, this M4 airsoft rifle is extremely rugged unlike polymer body airsoft guns, making it able to withstand high-impact BB contacts. 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. Aside its full metal build, this CYMA M4 also features a functional bolt release that lets you to easily adjust the one-piece metal hop-up. The CYMA M4 RAS II CM005 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 CM005 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. While CYMA CM005 shoots north of 400 FPS (w/ 0.20g BBs), you can upgrade the spring to play in indoor fields.

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.
