Magazine Holder with Computer
The magazine in a normal firearm would hold ammunition, but the magazine in the BlueSniper rifle holds something much more geeky - a gumstick-sized computer. You'll need to make the box (Figure 10) about 1.75 X 2 X 3.5 inches (4.4 X 5 X 8.9 cm) with the two sides extended to 4.75 inches (12 cm) to allow for a through-bolt to attach the box to the stock. You will also need to drill a small hole for the LED that indicates when the computer is powered.
While the magazine holder doesn't have to be big, it must be large enough to hold the small computer, wires and the on/off switch. The team from Flexilis chose to have the on/off switch inside the box, but you may find it easier to position it outside. Figure 11 shows how all the electrical parts are connected.

In order to mount the magazine holder to the rifle stock, you will need to drill a third hole in the stock about 3 inches (7.6 cm) in front of the trigger. Like the other two holes in the stock, you need to drill all the way through one side and out the other. The magazine holder will bolt through this hole, as shown below.
