Selling a complete 18" 6.5 Grendel Upper Receiver of unknown manufacture. The barrel has less than 200 rounds through it and shoots fine. I just decided it wasn't for me and decided to go a different route. Included is about 100 rounds of handholds (if you're worried about it I have no issues meeting at a range and we can burn through them), two mags and reloading dies. Would trade for a 5.56 16" upper or possibly 300 bo.
