I've been lurking around other forums for awhile, but came here when my interest turned to 6.8 (nothing in this caliber, but soon hopefully). I'll look forward to learning for awhile and contributing once I've got some experience with this caliber. I've been thinking of putting a new upper on one of my old Colt lowers, so I've got lots of thoughts about piston systems, 1:11 twist, etc...now I guess it's time to go get educated. I look forward to getting to know this great site. Thanks in advance to everybody for sharing your knowledge.
