Re: NXS 50mm or 56mm???
With my current rifle sporting a lupy 6.5-20x50 M1 turrets I find it a snug fit in the pack unless the pack doesn't have much in it. I can't remember the model of Eberlestock pack I have off hand but its a smaller one. I'm looking to upgrade to a larger Eberlestock though.
If your not questioning your sanity your not hunting hard enough!!!
