As with all the fmj finishes,the 5.56 is an impressive,wonderful color to have on an o-matter pair.Since the o-matter sunglasses were usually the base ones for oakley,the fmj models were a very significant upgrade to all collections.You instantly knew that you were dealing with something more expensive and different compared to all this o-that was around.The fmj coated sunglasses,actually seemed to belong into a league of their own,closer to the wires,that the o-matter ones.The 5.56 specificly,was a raw silverish to white tint,which can be very bright sometimes,and it's really wonderful.And,hey let's don't forget the added strength too.I'm glad to see them coming back in the newer pit bull.Bring some more!

This with Fire Iridium XX's is what hooked me on Oakley's. However, if they chip, you are with the standout black plastic underneath.

It's cool. I seem to like any of the FMJ coatings. They make any pair stand out more than they would have normally.

Grinding metal into small particles, mixing it with paint, and spraying the frames of Oakley shades results in an FMJ finish. The 5.56 version appears "satin white" and could almost pass for metal at first glance. Unique in appearance, the FMJ finish also provides extra strength to the frame without adding extreme weight.

This was the first frame that turned me on to Oakley back in the day. Apart from having been the first time I heard the term "Full Metal Jacket", I was attracted to the high quality look of this frame. It is flashy and harkens back to the old days of extreme color combos.
