Mykael--and others--The case from CMP came through in a stunningly short time, and it is a very well-constructed case. It is a little narrow, top-to-bottom, for a big rifle with a big 'scope. However, it houses my .22 bolt-action with a big 'scope, just beautifully.
CMP says it will hold a Garand, and I'm sure they're right. (For that matter, they're currently shipping Garands in this case at no extra charge for the case, so if you were considering getting a CMP Garand, there's no time like the present!)
If what you have is, for example, a heavy F-class rifle with attached bipod, you need a roomier case, but I'd recommend the purchase of the CMP hard case to anyone who wants a hard case for a smallish rifle.
