I'm a believer in bomb proofing everything... even stuff that's already bomb proof.
It will be of stronger material than the connector on any atty, so if you drop your REO with an atty on and it lands right on the atty, the
threads of the atty will give before the
threads of the connector. And, even though corrosion really isn't any sort of issue with the current connector, the SS connecter will be more resistant to any corrosion that might be caused by any
juice. SS is simply superior material for this purpose.... and it is just plain awesome Rob decided to be the first to design and have produced a full SS 510.
