Steve with Inland Empire Armory makes a resin DLT-19 kit for 250$. Assembled and painted is $350. The gun is hollow for electronics which I plan on adding to mine. He is making a modular DT kit for his DLT-19 so that you can quickly convert the blast to DT form. Should be ready early November. I think this is the best one stop shop for the long range DT blaster.
