That's really going to depend on the specifics of the rifle, but the Storage Unit is wide and deep enough to potentially hold a rifle with a scope. However, this particular storage unit only fits under the 60% portion of your truck's rear seats and does not go all the way across, so the rifle in question would have to be fairly short. If you have long guns you're looking to stow, you'd be better off with one of DU-HA's under seat storage units that run the whole length of the rear bench.
