Those are both really nice, UW. That B5 stock must be extra crunchy vs the creamy peanut butter of the other stuff. I think this came up before, but I should I presume you are lefty based on the light set-up?

What's your view on shooting the HK? I've heard less than flattery comments about them from a few sources. Any comparison you can draw against other piston offerings, like LMT? I love HK roller locks, but I just haven't been able to get excited about their ARs at those prices. Not saying I wouldn't love to have one. Maybe I should pick up the Brownells lower before July 1, but I just don't see myself dropping and $3+K on the parts kit etc when I still have a MWS to build.
