Unfired, 12" hard-use upper, .223, build done by Modern Armory - parts were all individually gauged, high quality, and assembled competently. The MA bolt has been heat treated, shot peened, high-pressure tested, and magnetic particle inspected, using sprinco springs and an S7 tool steel extractor. Gas block is adjustable, great for reliability tuning. It's hard to overemphasize the importance of the parts being gauged, and assembled right - it makes all the difference in the world for reliability.
It's an excellent build, but just gathering dust the last few years, and it's time for it to go to someone who wants to run it hard. The full BCG alone is worth what I'm asking for the entire upper - $225, shipped TYD.
