It took almost 4 months for my body + bolt + other internals to break-in, (ie cycle smooooothly.... :P)

(just let it sit, fully assembled ofr a while...lol)

EDIT: this I what I bought, G&P reinforced assemble set And AFAIK they are all steel, not aluminium....

Also, I would recommend getting a G&P outer barrel + G&P hopup rubber, (5ku and ratech didnt work well....5ku barrel wasnt straight... it was curving up.....:S)

Are you sure? That's what I was going to buy, but it states that they're made of aluminum alloy. Are you sure they're steel? Or is it just some of the parts that are steel?
