The Daniel Defense MK18 Rail Interface System was designed specifically to allow individual operators to free float M203 grenade launchers without the need for additional parts or special tools. These AR Handguards & Forends by Daniel Defense are built with attention to detail and high quality materials for performance and durability. The Daniel Defense MK18 R.I.S. II free floats a standard M203 grenade launcher and does so with a system that does not require drilling, port maintenance, or permanent modification to the host weapon. The free float feature was engineered in as part of the rail itself. This eliminates the need for additional rail sections and associated costs. The gas port and stress relieved metal surfaces of the rail prevent heat related damage to the weapon and its components. This rail is air tight and has an extreme tolerance and strength to prevent damage to the weapon and its reputation. The rail features an ambidextrous sling swivel studs on the rail allow for monopod operation. Integrate the rail into your existing platform with the Daniel Defense MK18 Rail Interface System II.

This handguard is a workhorse but also a work of art. This handguard fits amazing and is super easy to install. Fit and finish is spot on. It’s well made and worth the money for any regular SBR build and or clone build

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.

Ris III can eat it, quad rail > mlok. Truly the best quad rail money can buy for a sbr build. If you’re thinking about it, do it. Just do it. No think, just click.
