Very simple. I charge $25 for a front AR rewire, including connectors of your choice. The biggest issue is making sure you put small blade connectors between the mechbox wiring and the front wiring, so you can get the gun apart later on. Use no larger than 16ga wire or you might have a problem getting through the upper receiver into the fore end.
