5.56 AR upper

I have a 5.56 AR flattop upper for sale. Midwest industries upper with Leapers utg pro handguard. Yankee hill machine flash hider and magpull Mbus flip up sights. Comes with bolt. No carrier or charging handle. Looking for $275 shipped. Would also trade for 700 LA mag BF for a build I'm trying to put together

Length and rounds through?

Barrel is 16". No clue as to total rounds but I personally put right at 150 through it

bump

Maybe throw in a sig tango 4 4-16x44 ffp scope with illuminated reticle in moa and trade for another optic in a 5-25 range?
