CYMA Full Metal M4 AM005 RAS II CQBR Airsoft AEG Rifle - BLACK

The CYMA M4 RAS II AM005 AEG is made entirely of full metal (upper/lower receiver, rail system, buffer tube and outer barrel), making it extremely durable and able to withstand the abuse and stress encountered in any airsoft game. What makes this M4 stand out from all other AR type airsoft rifles is its RAS II rail system, made entirely of anodized aluminum, that features an integrated, unique riser rail that sits past the delta ring. This not only eliminates wobble but allows players to attach low-mounted red dot scopes and sights, giving you improved view of your scope especially when using bulky eye pro or face masks. Unlike other airsoft M4 models, the full metal buffer tube is attached solidly to eliminate wobble. Additionally, this CYMA M4 AEG shoots up to 430 FPS (w/ 0.20g BBs) and features a fully functional bolt release, giving you easy access to the one-piece metal hop-up adjustment. When looking for a good airsoft gun leads to an AEG that comes with a full metal body, hard-hitting FPS and unique rail system, the CYMA M4 RAS II CQBR AEG is a perfect pick!

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.
