As previously posted, this ANCIENT Colt pre-ban range rental followed me home a while back.....
It took until the last month for me to get to finally disassembling the upper, and partially stripping the lower.
The upper was a soup sandwich, nigh on to THIRTY years of crud, sludge, and carbon buildup. The gas tube was so encased in carbon buildup it took vice grips and a mallet get it out of the front sight assembly and upper receiver, even a soaking in Kroil wasn't too much of a help.
Let me put it this way, this rifle has a history that's too "interesting" to get into here.
A few weeks ago I happened to come across a take off FN M-16A4 barrel at my local gun shop hangout that was well in excess of half the price I would've gotten my planned LMT replacement barrel for. So I bought the FN barrel. And this afternoon I installed it on the Colt upper. I'm going to do the final installation on Tuesday, since I had to go out in search of $#!+ tickets (better known to civilians as toilet paper) and paper towels, just to be on the safe side.
Here are a few pictures of the lower. This wasn't quite the soup sandwich that the upper receiver was, though it was very dirty.
On the shopping list at the moment are a set of 5.56mm Go/NOGO gauges, an at bare minimum Mil-Spec bolt carrier group, rifle length buffer spring, compensator crush washer, and Loctite to replace the three decade old thread locker I soaked and scraped off this week to set the oversized pivot pin and butt stock screw in place.
