just wondering why you use extender in that MCW30 ? can it be done with the BP 45's only ? or probably the BP 45's can't get with mcw30 coz it have countersunk in the thread ?.. i wanna do the same thing, but still confuse about it will fit or not..

thx..
the 45 by itself wont go into the housing on the MCW-30 and thus it wont seal beacuse of its sunken O-ring design. The ST transfer adapters have a non-sunk O-ring the fits in the MCW-30 with a nice and snug seal.

personally I think it looks better with the adapter too
