Some Colt LE6920s have the Cerro Forge Keyhole on the upper and the lower, some have the C and the square on the upper and the UID label on the lower, and some have the Cerro Forge Keyhole on the upper and the UID label on the lower. Not that I am lying awake at night wondering about this, but why are they marked differently? Is one more desirable than the other and why? Thanks ODT.
