Stick, hang with me a bit here. I'm really liking the idea of that 6mm Grendel, but help me out: this is the same as .243 LBC and 6mm AR, no? I'm gettin so much white noise of the webz I can't tell what's straight and what's not. I can see both lowers morphing into this one to be my daytime guns. Still wanna know more about that 6.5 Timberwolf, though.
