Bought this as a factory noveske 16 inch upper. I needed the receiver and bcg for another build so the upper is currently a bcm receiver, unfired noveske 16inch chf 300blk barrel,noveske gas block and noveske rail. Will sell for 550 or throw in 250 rounds of 300blk for 750. Wont sell the ammo first. The only trade I need is a complete g19/g45 gen 5 upper or 19x upper. Shoot me your cell for pics
