Thanks for the input. It looks like I will have to go with moving the gas port to the pistol position, as I tried the over size port, and still no go. It did get a lot close, and I could go a little larger, but I don't think it will ever work with subsonics in that position. Does anyone have any specifics, or websites where I can get them, as towards where the new port is locate, and how, and with what, do you fill the old port?

I think my gunsmith friend and I can do this, if we know the particulars.

Thanks
Joel
