A.J. George reviewed the new Daniel Defense DDM4 Lite Rail II in the January issue: "Most rail systems, although highly functional, add a lot of weight and typically cause the gun to be very front heavy, leading to quick shoulder fatigue. Daniel Defense's new Lite Rail II gives the DDM4 a huge weight advantage over most similar systems. A 7-inch carbine length Lite-Rail II weighs in at just 8.7 ounces. The 12-inch Lite Rail II is a hair under 14 ounces, a few less than most of the competition."
