TSD l96. I put the bb and let it slides down inner barrel, and it seems pretty a good thightbore inner barrel than my stock m16 G&G inner barrel which is 6.04mm.
I tested both inner barrels. (stock TSD l96) I let the bb rest inside the inner barrel and I don't see a big gap around the bb. For the other inner barrel, stock m16 G&G inner barrel has a big gap around the bb. Maybe this pic I made is more clear:
I am getting the Mad Bull 6.03mm Black Python Inner Barrel for APS2 499mm. Has any one ever use this inner barrel?
