Ok that's what I thought. Copper color = chrome silicon, gray = stainless.
By the way, has anyone ever used the CMMG braided springs?: http://cmmginc.secure-mall.com/item/...ent-Spring-915
I used them before and wasn't impressed, they don't fit more than 28 rounds in a mag, even after cutting 3 coils off the spring. I ditched them and put USGI springs back in my mags (glad I only bought 3 to test). Just curious if anyone else had the same experience.
