Well, by Pythagorean Theorem a^2 + b^2 = c^2; so, 11.5^2 + 17.5^2 = c^2
138.25 + 306.25 = 438.5 = c^2
c = 438.5^-2 = 20.94 in.
But the sides aren't vertical and the corners are rounded, so at the bottom it measures just 20inches tight. If you keep the barrel off the bottom a little bit, which you would do anyway, it'll fit! I don't think you could get the receiver/magazine and the barrel in there at the same time, however.
