Taking a closer look at the vest, it's not an M69.
The flap is on the right side instead of the left, also a small tab above it.
There appears to be no flap on the right pocket.
Not sure if there is a left pocket behind the dual mag pouch.
Webbing (I'm guessing for the side adjustments) start at the front zipper.
Greeblie window pocket left side.
Looks like it's in a few colors (tan, green, brown?)
