Well I was playing with the .58 Carbine this morning, and I couldn't for the life of me figure out why the bore is so much brighter than my GPR (<<brand new barrel). So I did some googlin, Investarms chrome lined the bores on these things. My question is why? You are not running a 100 rounds down that pipe at one time like you would with something like a AR or AK. And my understanding is chrome lining is done for the purpose of lessening the wear on a barrel from lots of rounds fired. Just thought it was wierd to see chrome lining on a ML.
