Looking for one of these to mate with my Spikes 9mm Glock mag lower. Seems to be out of stock everywhere, but going price (in stock) is about $110. I'd be willing to pay $200. Located in Firestone 80504, willing to drive any reasonable distance for pickup. Does anyone have one and willing to sell? https://www.joeboboutfitters.com/Spike-s-Tactical-9MM-Forged-AR-15-Upper-Receiver-p/sp-sft902d.htm Text me @ 720-691-7273 or comment here Thank you, -Alex
