For sale or trade 16" FSB Aero upper chambered in 5.56x45. It's a great lightweight shooter! Was my backup/spare upper so hardly saw any use (sub 100 rounds). Comes with mounted and zeroed Sig MSR red dot with a Magpul MBUS rear. Overall super clean few signs of wear. No BCG/CH. Trades considered looking for 5.56/.223 9mm .357/.38 or G19.5 G22.4 components. Let me know what you've got open to offers. TEXT FIRST BEFORE CALLING thanks
