That will be an interesting read. I was wondering the same thing.
Got a new M4 in & set it up for coyotes. Topped it off with a Leupold 3-9x40 & it'll do 2-2 1/2 inches at 100.... /ubbthreads/images/graemlins/crazy.gif
Was looking on Model1 today & found the 16" freefloated varmint upper at $360 with the Shaw bbl. I suppose some decent testimony will help, from people that have shot Shaw barrels.
The kind of accuracy I got from the standard M4 bbl. is unacceptable, so, I'll switch. Can't hurt... /ubbthreads/images/graemlins/grinning-smiley-003.gif
