Bulldog M4 AEG rifle

Great little gun just needs a new rubber or a hop up system and a decent mag for this due it it’s feeding issue works fine in semi auto but dose not feed in full automatic happy to swap for a pistol or another airsoft gun pick up only in S6 region Dose not come with a mag battery included Comes with the sight on it but it’s broken I have the iron sights for it i will include them aswell
