[OBO] Sig Sauer 516 Complete Upper - New - Price Dropped! in Tucson, Arizona For Sale

Selling my new, unused Gen 2 Sig 516 upper. I bought this for a build and ended up going a different direction after I'd already got it. I paid $850 for it plus shipping, my loss is your gain, this is a screaming deal. I just need to get rid of it.
Never fired aside from factory test firings. I still have the original manual for it, too. Unfortunately the box got thrown out. Adjustable gas, floated quad rail, the whole works. This is an awesome piece of equipment. I'd keep it if I didn't have other projects in the works.
Pic of complete rifle is the upper mounted to one of my lowers. Lower and optic not included, obviously.
Email or text me @ 520-344-xxxx and we'll work out the details. I'm on the NW side, but willing to meet you somewhere closer to you if needed.
$700 or best offer.
