There was a time when I saw some value in a folding stock shotgun, but now not so much. Unless you need a folder for storage I'm against them. I believe the collapsible AR style stock is a much better direction to go in. Fully collapsed the weapon is reasonably compact, yet you could still snap the gun to your should and deliver accurate fire. The folded folding stock doesn't give you a solid aimmed fire option. The collapsible stock also gives you the ability to easily adjust the length of pull.
There is in life perhaps one fleeting moment when the courage, dedication and resolve of one man gambling against all odds will alter the destiny of nations.
