Chrome lined bores are probably the best innovation in shotgun barrels in the last few decades. While it is not a necessity, and proper maintenance makes it moot, there will be many more perfect Beretta, Benelli, Perazzi, etc. barrels than American manufacturers who don't plate. Chrome lining is nigh immune to corrosion, and much quicker, and easier, to get squeaky clean.

There are just too many shooters out there who never clean their barrel bores.

May God bless America and those who defend her.
