Dont really use this gun much. Its a factory Spikes lower save for the RRA A2 stock and Ergo grip. The upper is a Bushy dissapator with a RRA chrome BCG and KAC RAS M5 rail with some rail covers. Shoots great just more into scoped stuff these days. Lower has maybe 150 rounds on it, upper around 350. Any questions just ask. Prefer email for contact and paypal discreet or USPS MO for payment. Price is $800 shipped.
