Tight fit but doesn't flop around. That's good.
I gave it 2 stars because it DOES satisfy a basic need to keep your carbine clean. That said, the fabric is too thin, the muzzle end is not tapered or reinforced, and the leather tabs are embarrassing. The zipper works well and the strap is decent. For basic storage, one of the polyester stretch socks would be better, but for reenacting where the cover may get ruined, maybe you can swallow your pride and use it. For the price I do not recommend it.
Outstanding a prefect fit.
