I was thinking,  if the breech fits and that amazon review said he had to drill a new transfer port in the barrel, wouldn't having 2 transfer port holes cause a loss of air?  

Also, that would mean the transfer port on the new breech would line up with the one on the air reservoir.  I may be able to cut the barrel down eliminating the old transfer port and drill a new one to match.  I'm just afraid of the measurements.  One hair off and it's ruined.  Any thoughts?
