DIY Molding Drones are made for the professional and hobbyist alike. These castings are molded from actual pistols/mags/lights out of a high-temp, durable material that has a shrink rate of .001 inches per inch. This makes for unparralleled accuraccy in our molding drones. Magazine drones are molded with a round in place for proper construction of magazine carriers. These drones are workable, so if you want to make custom alterations it is no problem. Feel free to sand, cut or glue alterations as you see fit. Our goal is to make it easier when you Do It Yourself!
