Can You Say Aluminum?

They're Baa-aack. Finally, after months of painstaking effort to redesign, improve, and manufacture the new MTS "FR" Head, we have succeeded. Here's a glimpse of what they look like (the quality is in the details), and some verbiage on what to expect. If you have other questions, give us a call. The first run is almost (if not already) sold out, but the 2nd production run is at the machine shop.
