I just sent Kampfeld a package 20 minutes ago. I couldn't quite pull the trigger on the Campfire knob. I love the looks of them but don't know if I would really like it. I was also concerned about exerting extra force on the skeletonized handle.
Personally I don't like to carry rifles with crap sticking out off the side. Turrets on top are great but I hate a M1 sticking out on a carry gun. That's why I love my pos, in accurate, forearm rattling, loud safety clicking 760
One of these days I would like to hit one of the gatherings and maybe one of you fine fellows could change my mind on them.
