Cyma CM.135s Sai blu AEP

Only used once during a CQB skirmish as was bought to be a backup. Have since bought a new RIF so looking to sell to fund upgrades. Has had roughly 500 rounds through it, mostly at home plinking. Lipo battery/charging cable included. AEP itself is in very good condition having been hardly used for skirmishing. 4 AEP magazines and 2 AEP mag pouch inserts included.
