New, never fired, shipping and fees included. Arcturus "Centaur" (Arex) AKB15 AEG. Original box, manual, back up sights, 550rd hicap mag, and Arcturus patch included. There are less than ten of these in the United States currently. Steel body (and most of the moving parts), ACR style folding stock, enhanced fire selector, and built in magazine spacer. Extremely well built, heavy, and these shoot 400fps on the nuts. Will take money off if you want multiple units, or if combined with other listings. PayPal only, not interested in trading, ships via FedEx (three day). Thanks in advance.
