The Omega Rail is the newest premium line of AR-15 drop in hand guards from Daniel Defense which were developed as two piece drop in style replacing your existing mil-spec polymer hand guards. The benefit of this rail system is that you have a true two piece free float system which you can easily install without having to press a gunsmith into service. Additionally it's worth mentioning that the hand guard is CNC machined from aircraft grade aluminum with a mil-spec hard coat anodized finish. Additionally should you decide to attach a sling to the rail the integral QD sling swivel mounts are rotation limited which the M-LOK modular attachment system provides you with a ton of modular attachment points. All of the Omega Rail fasteners are made to Military specifications so you never have to worry about the hand guard letting you down.
