I released a video a couple weeks ago about the AR Builder Board. If you are just learning how to build an AR lower, this thing cuts a HUGE learning curve down.

Let me know what you think about this product. Personally,
I wish I had come up with the idea.
This would of been cool to have when I first started building. New builders are going to appreciate this when they find it.
