It's clear from the photo that the "arctic" stocked rifle has knobs with 4 lobes.

Every time I see these type of oversize knobs, I wonder if the designers understood that scopes should never actually be removed unless there is a problem of some sort which requires it, and I also wonder if they have ever been off a range carrying gear which catches on branches and kit...

And when the knobs are on the bolt side....have they ever run a bolt under stress, from an imperfect position??
