The are named after rounds of ammunition. 5.56 is a standard AR platform rifle round and the 7.62 is the standard round for the AK platform. - brian

Thanks Brian! That does ring a bell now that you mention it. I appreciate it.

Does anyone happen to know what inspired Oakley to chose the name Heater for the original M-Frame Heater lens shape?

I was today years old when I learned the names of the various groups of traditional battle shields such as the Kite, the Scuta, and the Iberian, among others. One of the groups is called Heater, and apparently was so popular in one variation or another that it became the most often used shield in Armorial Heraldry. I just couldn't help wondering if this was the inspiration for the name of the lens shape. It certainly wouldn't be out of character for Oakley.

But I digress. Anyone know where the name Heater comes from?

I asked Peter:

Heater was a reference to throwing a fastball in baseball. The rest were names associated with what was considered cool for the time or descriptive about the lens shapes themselves.

Awesome, Dann! I appreciate it!

The Gold Iridium lens on the Mars Leather looks brighter and more transparent than other Gold Iridium lenses to me. Anybody else feel that way?
(Is it actually Leather Gold http://o-review.com/database_detail_lens.php?ID=1129)? )

What's the mass of the Time Tank w/ titanium wristband?

Answered my own question. Can you please add the mass to the DB, Dann ?

Will do
