X7 Development History
The X7 is the 7th and most ambitious version of AR-15 developed and sold by NGA. All aspects were reviewed. Which parts to improve and make in-house. Where to source the best parts? Tolerances. Springs. Coatings. Machining. Design. Everything! One of these days, if there's a minute or two of reflective time, we'll list all the parts developed and tested for this project.
