I've started an AR build thread, and a build is underway as we speak.
The completed AR will be a component of a much larger idea.
You see, I'm a James Bond fan.
I contemplated what Bond would use as a rifle, and came to the conclusion that in the real world, he would need something NATO compatible, but an off the shelf M-4/AR/M-16 just wouldn't do. Bond has a Q Branch, his stuff would be custom. Hence, the build.
I've also concluded that I'm getting old. At 45, bruises last a week that used to be gone in 3 days.
But since I was about 8, I wanted to be Bond.
So I'm doing it.
