It uses the same basic hardware as my N-AR and others. You will need a m5x50mm to attach the stock and a big soft spring for in front of the charging barrel(see pics). This goes together just like my previous designs, the pics should be enough to get you through the build. Assemble the LOWER, UPPER, and FRONT first. Then attach the FRONT to the UPPER. Next attach the LOWER to the upper assembly. Then the stock can be attached.I wired each section separately before final assembly. There is room to the left and right of the switches for the wires to run but it is tight if the wires are overly long. Make sure you wire this as minimalist as you can.
