Not sure it is supposed to do that...

Bought this on Ebay, received it today. Thought I'd head to the range for a quick 50 after work and put it through some paces...

Didn't even get to fire one off, as soon as I took the headcover off I heard a rattle within the head... didn't hit a ball with it, put the headcover back on and off to the side; seller contacted about return.

Not what I'd expect from a demo which has seemingly hardly been hit and lived most of its' live on a shop rack...

Loose epoxy broken off and rattling round.

Heat he head up over a boiling kettle and it'll disappear.

As gareth says probably epoxy, if that rear weight comes fully out you may be able to tease the offender out through the opening.

The wee dummy 'tuning port' feels loose, there is very slight play on it; I thought I might be able to tighten it with my M3 tool but it is too big.
