The Daniel Defense RIS II MK18 freefloat handguard is one of the toughest and most effective rail systems for AR-pattern rifles available on the market to date. Utilizing their patented Bolt-Up barrel nut system designed at the behest of the United States Special Operations Command for the SOCOM II program, the MK18 rail features an incredibly rigid two-piece design optimized for use with the standard M203 grenade launcher when the lower section is removed. Incredibly rigid when installed yet weighing in at just 17.7 Oz, the RIS II M4A1 free float quad rail is the perfect option for clone-correct builds or anyone looking for the toughest rail on the market.
