I'm looking for comming WE & Prime CNC Magpul style upper/lower receiver, (est. 3K) plus a custom made 3061 steel CQB one piece barrel (reduce weight).
Thanks bro. Noveske your M4 flat top really fit (too tight that I've to seek professional machining work to fit) into the INO! Now I can fit the Troy MRF no problem and shoot no problem.
