Looking to sell my Daniel Defense DDM4 300s as I am trying to save for a home down payment. This upper has had the original rail replaced with a Daniel Defense Rail Interface Sysyem (RIS II) rail which is a $500 rail new. Approximately 1000 rounds have been fired through the gun since new. I have also attached a Surefire 4 prong flash hider and a Daniel Defense QD mount. Comes with original vertical grip and rail covers. 


Open to trade for a ta11 or ta31 green chevron reticle.
