MODIFIED WalMart Ignite Black Ops M-4 with working AN/PEQ-2

My DBOYS AN/PEQ-2 has been modified to include a real WORKING laser and flashlight... and STILL fits the battery! I touched up the entire gun with some silver paint to give it a "seasoned" look. I also ran the pressure switches for the light and laser out the back to use on the vertical grip. The front handguard is an actual AR-15 Magpul MOE guard. I removed the head-sink and had to drill a new pin hole in the front sight to move it forward about a 1/4 of an inch to fit it properly. I also added three MOE rail sections to it for mounting furniture. Stock is a real MOE Magpul CTR. Pistol Grip is a Magpul PTS Grip. Forward Vertical Grip is a Magpul PTS. Rear backup sight is a Magpul PTS. Aimpoint Red/Green Dot Sight and Aimpoint 3x Magnifier with flip to the side mount. MODIFICATIONS LEFT TO DO: 1. I have two Magpul Clips on order. 2. Get a piece of bicycle inner-tube to put on the vertical grip to hold pressure switches instead of tape.

How'd you modify the peq?
