Lately I have been reading about folks doing guns in tungsten(iirc). I guess it looks different depending on the angle. Might be interesting with black for contrast.
I'm building an AR pistol with a Huntertown Arms Dolos quick detach barrel system. I'm wanting to do the stripped upper, stripped lower, and the handguard in tungsten. Are you taking work now? The handguard is a simple aluminum cylinder. Are you taking work right now, and what would be a ballpark price for them in tungsten? They have not been assembled yet, so there would be no need to take anything apart.
That bronze AR looks great, by the way. I had a hard time deciding between tungsten and bronze, or even blue titanium, but I'm leaning toward the tungsten at this point.
