The Troy battle rail has a cult following. Lots of run and gun guys use them. They also have those silly grommets you pop into the holes for a better grip...which, though they look goofy are *great* for gettin your grip on.
Get in line, I'm totally going for a Seekins billet upper/lower combo with a Diamondhead rail, since Mega is no longer making monolithic tubular rails. Make me sad.
