I emailed Lehigh Friday night about a conversion for my original disc rifle. A short email with a few questions of my options and his products available for upgrades. Dave responed on Sunday with a honest opinion and not once pushing his products. And I quote" The total cost of this would be around $175 which is a significant investment in my opinion" Then he went on to suggest T7 powder and enjoy a fine gun. Well after reading his email I ordered some 185gr .40's from his company. In todays world you just don't run into people like this.
