Fn fn15 m16a4 20" upper

FN FN-15 AR-15 20" upper with BCG & Charging handle. This is a legit factory built FN M16A4 upper part #36427. I bought about a year ago from Brownells and have fired about 200 rnds through it. It came with the factory drop-in handguards and I upgraded it to a free float 12.7" Aero Atlas R-one M-lok rail, I can easily put it back to stock if you want, I have all the original parts and will include them in the sale. These uppers are pretty much impossible to buy anymore and are $699 plus tax and shipping. The Aero rail was $189 and I also installed an UTG pro slim fixed rear sight $39. So easily over $900, if you could find and build one the way my upper is built.

Asking $600
