guys project as I wandered around the web.
I have considered this kind of modification to a guitar case. I even managed to buy a Fender guitar case at a yard sale for $5. My son grabbed it and actually uses it for his guitar.
In VA I don't recommend this kind of project unless you have a concealed carry permit.
Rifles, carbines, handguns and even shotguns could work in something like this. Excellent camo for my AR-10 and ten extra mags. And no hippies fumbling with their iPhones to call 911 as I order my black quad espresso at Starbucks.
--Even though I love making hippies cry, sometimes it worth the warm quiet secret inside...
