I just got a case for my M4; I almost bought an arrow case for $25 it was short and would work but looked flimsy and it needed padding. I ended up getting an Planto (?) 'Assault Rifle Case" for $45 it's a soft case but it's pretty nice. Well well padded and has a loop for a lock on a zipper also comes with a pocket for mags and a shoulder strap. it's 42" so it can fit all of my other guns.
