Cyma M4 AEG (Inbuilt Silencer – Black – CM513 – Tan)

PLEASE NOTE: The use of an 11.1v or higher battery will void any warranty unless it is specified as our recommended battery for that particular AEG. Most quality airsoft guns do not come supplied with a battery or a charger.  On the rare occasion that they do have them included this is specifically mentioned in the product listing.   If they are included they are considered free gifts supplied by the manufacturer and batteries/chargers cannot be returned if faulty. We recommend that when purchasing an airsoft gun you also purchase a new quality LiPo battery and charger for maximum reliability.
