I was wondering if the LMT barrels are park'ed under the front sight base like the Colt & BCM, OR not like the RRA & BM?? All info is greatly appreciated!

Like JTAC says, they are not.  The fact is, once you drill and pin the FSB, the final product looks better when you park as a unit.  That and it saves time.  Everything is uniform in color etc.  If it makes any difference, I don't think the fact that it is not parked under the FSB is that big of a deal.  We take off lots and I have never seen anything but very minor rust but keep in mind these are civvie rifles.

It seems that only one of my barrels (Colt) is parked under the FSB! That's the one that doesn't have a FSB attached so, it works out in that respect. I'm just trying to decide on whose complete upper for my next 16" M4 build. I've got it narrowed down to LMT & BCM.

My LMT (had) a ring of bare metal behind the FSB, like it never was completly parked before or after.
