Miller's right. CSM's mid priced RBL has Titanium Nitride coated bores and has the exact same 4140 barrel material as his high end guns (unless you specify Krupp, and why would you? can you recite some specific advantage or metallurgical characteristic that is "better"?). The "advantage" of chrome would be especially beneficial for target shooters that put more rounds thru their guns (or don't clean at all) or waterfowlers for added protection, IMO.
