Hi Gleason,
Who are you suggesting, should Buy a ML10II and be done, I have built 4 smokeless ML guns to date and supply vents for 5 ML10IIs (all in the Family) and a ML10 that I helped build from parts. as you know the old 10 takes a different style replaceable vent.
Being this is a Black Powder forum, I have reframed from talking about the origonal Black powder substitutes that I use in all my user built guns.
I just can't go out and buy something I have the time to build.
Ken
