From everything I was taught there are no standard M4s in NSW they are all "Mk18s" since the Mod 0 came out.... This is what I heard from dudes and the term we were told to use to sell shit to commands. Granted to some guys as long as they spat 5.56 they were M4s...
EDIT: The other thing to realize is that each team has an armory as well with full time armorers, they can set their weapons up however they like, so they can take a 10.3in weapon and slap a 14.5in barrel on there should the so choose, but the ballistic variation between the two within 300 yards isn't that dissimilar so unless you plan on actively engaging a target way the hell away, why bother, plus at 14.5in the Mk17 provides a far better platform for distant engagements, and they are as common as coke cans.
