Anothet question for the Horde. What is the advantage of a chrome lined gas key? I've read reviews of BCGs where people gripe that the gas key isn’t chrome lined. It seems like a chrome lined gas key is milspec. Am I missing something here?
Also, do chrome BCGs (e.g. Young Mfg.) cause more wear to the upper receiver as opposed to BCGs with other finishes (i.e. phosphate, nitride, DLC)?
