If you planning to build locally, may I suggest?

That one on the far right has a most = unrestricted airpath. I have only a .22 and .25, but pretty much you can calculate from the picture. Now for a .30 cal you better use a CAD because of a wall thicknesses.

Who makes the transfer port on the right? It looks good.
