I have a 34" Savior Rifle case and I had to finally put a my Law Tactical folding adapter on my 16" AR to use it. They also have a 30" rifle case as well. I went OD Green for it. It is fine for going to the gun range and I suppose a SHFT event as well. Realistically I would break my AR down so it fits in a smaller back pack but if SHTF event I would not want to put it together to use it.
I'm pretentious enough to act like I'm a musician. And if a 75 year old old broad so dares, so can anyone, really. I even take a guitar to talks I give on plant breeding and sing songs I've made up about it. However, if I packed a gun in my guitar case where would I put the guitar? Even in these trying times, I think I'm lots more likely to feel a need to sing a song than to shoot somebody. Or at least than to shoot more people than Buddy, my trusty 686 snubby EDC, could deal with. (And if I carried all the extra speed loaders or mags on my belt people seem to recommend these days there would be no room for the harmonica.)I am nowhere near skinny, alt looking nor pretentious enough to act like I'm a musician
And make sure you're not totin' it around after the slopes close for the season. That'd pull some unwanted attention your way...
I dont have a diaper backpack but we have small diaper sling bags...I have found that the best incognito bag for a gun is actually a diaper back pack. No one will think twice and no one will want it thinking it has baby crap. They have clamshell openings to fit folded firearms and pockets for magazines (diaper pockets).
