Andy's Review of Daniel Defense MK18 Rail Interface System II, RIS II

If you're seeing this then you already know about this rail. It serves a single purpose that that is for the fighting rifle. Not a range toy or social media star etc. The reason you don't see a lot of reviews is because the people running these rails are using them not posing with them.

It is heavy.. yes but that also means it's rock solid. There is zero visible flex on this rail, which means your back up irons, IR setup will hold and maintain zero. Probably because it passed the military testing requirements for that. If you want the absolute best free floating rail ever made look no further. Tinder hands need not apply.
