Product Details
The Daniel Defense MK18 upper is a proven, no-fuss choice for anyone building or upgrading an AR that needs to handle real work. This complete upper comes ready to drop onto a compatible lower receiver, with a 10.3-inch hammer-forged barrel, flat-top rail system, and that reliable 5.56 NATO chambering that shoots what's available. The 1:7 twist rate stabilizes a wide range of bullet weights, so you've got flexibility. Black finish, clean lines, built to last.
