I've searched and can't find anyone who makes air stripper cones that will correctly fit the Impact's LDC. With the .30 caliber and on high power setting the thing really barks loudly. It would be beneficial to have a set of these air stripper cones that would fit into the LDC on cutting down the turbulent air as well as the ear splitting rush of exiting air. Because of the popularity of the Impact, anyone willing to take on this project with their 3D printer could make a decent profit in short order. Here's an example of the tried and true air strippers, with others being made in similar fashion. Anyone willing to give it a go?
