You start out with a stock that all other components will be attached to. The guys at Flexilis decided on the Ruger 10 / 22 folding stock from Ramline, but you can use any stock you want. You can even make the BlueSniper without the stock, if you want to be more discrete about scanning Bluetooth devices. The stock just makes the BlueSniper look more menacing, not to mention really fun to hold.
The Ruger stock folds into a compact size, which can be stuffed into a duffle bag. Since it is plastic, you can take it through airport security without too many problems. In fact, the Flexilis staff has taken their BlueSniper kit past the watchful eyes of the Transportation Security Administration several times.

At the business end of the stock, you will need to drill two holes all the way through. Since the stock is plastic, you can use a hand power drill, or a drill press machine. The first hole will be about 1/2 inch (1.3 cm) away from the end, while the other hole will be 3 inches (7.6 cm) behind the first hole. You will also need to sand down the ridges, so the antenna coupler will have a secure fit.
