Metadyne Industries 8.5" A5 Rail Integrated System
The Ultimate in rail integrated systems. Most RIS hand guards use plastic rails screwed onto aluminum tubing. This shroud is CNC machined out of a solid piece of 6061 aluminum. No plastic, no screws. Finished with a satin black hard anodize coating, this shroud matches the A5 finish flawlessly. A barrel adapter that the body threads onto and locks with a knurled ring, similar to assault rifle shrouds, allows this component to be completely free floating with no set screws to dent your barrel. This means you can thread your barrel on and off independently of the hand guard. This system will not bend, flex, twist, snap, fatigue, loosen, or fail. Simply put, this is the best RIS hand guard on the planet.
