The Daniel Defense Omega Rail 7.0 is a drop-in free-float quad Picatinny handguard for AR-15 and M4 rifles with a carbine-length gas system, fitted with the supplied Allen wrench and no modification to the rifle.
A free-float rail you can fit at the kitchen table — no barrel nut change, no gunsmithing, no special tools.
Most free-float rails mean pulling the barrel nut and replacing it, which is the step that sends the job to a gunsmith. The Omega Rail does not: Daniel Defense designed it so the individual operator can install it with the provided Allen wrench, requiring zero modification to the weapon. No barrel nut is supplied because none is needed.
What you get for that is a genuine free-float tube — nothing touches the barrel, so a bipod, a sling under tension or hard support-hand pressure no longer moves your point of impact. That matters most to exactly the shooter this rail suits: a UK straight-pull AR-15 owner working the rifle by hand and shooting deliberately from a bipod, a bag or a barricade. The upper rail platform stays uninterrupted so the optic and any backup sights sit on one plane, and there is an integral QD sling swivel mount with a rotation limiter built into the rail.
It is CNC machined from aircraft-grade aluminium and Military Specification Type III hard-coat anodised, and all fasteners are to military specification. At 7.6 oz (215 g) for a full quad rail it is light for what it is.
Fits AR-15/M4 rifles with a carbine-length gas system, including UK straight-pull AR-15 builds. Rail length is 6.88" (175 mm) and inside diameter is 1.08" (27 mm), so the tube has to clear your gas block along its full length — measure from the receiver face to the front of the block first, and note that a standard front sight base will not pass through a 1.08" bore. No barrel nut is supplied and none is needed. If your rifle runs mid-length gas, take the Daniel Defense Omega Rail 9.0 instead, which is the same rail at 8.88".

No. Daniel Defense designed the Omega Rail so it installs with the provided Allen wrench and requires zero modification to the weapon. That is the whole point of the design — most free-float rails require the barrel nut to be removed and replaced, and this one does not.
Carbine-length gas. The rail is 6.88" (175 mm) long and must clear the gas block along its whole length, so measure from the upper receiver face to the front of the block. For a mid-length gas system take the <a href="/products/daniel-defense-omega-rail-9-0">Omega Rail 9.0</a>, which is 8.88".
Inside diameter is 1.08" (27 mm), which clears a low-profile gas block but not a standard A2 front sight base. If your rifle still has the triangular front sight base, that has to come off first.
There is an integral QD sling swivel mount built into the rail, with a rotation limiter so the swivel cannot spin under load. You supply the push-button QD swivel. Every face is Mil-Spec 1913 Picatinny, so lights, foregrips and other accessories clamp on directly.
