Hi Timothy and welcome. Yes, fortunately, this model is. I also store my firearms in rust preventive bags such as : zerustproducts.com/products/firearms-ammo-weapons/vci-gun-storage-bags/ --- Cheers and stay safe!

Tim, it's on par with other similarly priced shotguns. Just keep it clean/lubed and you should have no problems.
Stay safe & have a great day!

I slather a thin coat of oil on my rifles stored in my safe just to help. A lil prevention goes a long way.

its the same as most shotguns clean lube and store it oiled in a dry place and it will be fine
