Hey so I have this AMAZING m-4, which shoots great and everything... Built the gun but got bored.. like in a matter of 2 weeks... haha So that is besides the point. This weapon is for anyone who wants to build a complete gun from scratch and say they built it! I will send ALL the parts that make the gun shoot roughly around 35-40 RPS and shoots 400 FPS. I will send ALL the products disassembled and ready to be put together. Each piece will be bagged separately. Again this will come with all the parts for the gun. Parts: Internals 1. JG gear box 2.
