need help with tanaka m700 takedown model

[bleaches]

iv owned this gun for over half a yr and it kicked ass. but one day i accidentally hit the guns front part really hard nd the whole front section became unstable :sad: , it wobbles a little when i hold it. basically it has gaps from the piece of metal that connects the 2 sections when i try to hold it. :-?

im guessing that when i hit the front part i accidentally bent the inner barrel, thus screwing up the accuracy. :cry:

the real problem is that i have absolutely no idea on how to take the barrel apart from the hand guard. i tried unscrewing the front bipod pin, but the barrel is still caught by the connection piece. then i took some screws of that nd somthing inside the handguard (i think) is still holding the barrel to it. :banghead: :banghead:

can anyone tell me how i can fix this problem? :sad: will be really really helpful
