Product Overview

The Daniel Defense Rail Mount QD Swivel Attachment Point is a Rock & Lock sling mount for Mil-Std 1913 Picatinny rail, and the Heavy Duty Push Button QD Sling Swivel is included in the box.

This is the one that comes with the swivel. Buy it if you do not already own a push-button QD swivel — it saves you a second order.

Daniel Defense makes two sling mounts that are easy to confuse. This part, 03-021-30029, clamps to Picatinny rail and ships with a Heavy Duty Push Button Quick Detach Sling Swivel in the box. The other, the MFR Rail M-LOK QD Sling Mount, 03-021-15136, attaches to M-LOK on Daniel Defense rails and does not include a swivel. Same brand, same job, different interface and different contents.

The mount itself lets you put the swivel anywhere along a rail system rather than at whatever fixed point the rifle came with, and it is shaped to stop the sling tangling on itself. Installation uses Daniel Defense's patented Rock & Lock one-piece mounting system, which simplifies fitting on MIL-STD-1913 rails. It is machined from 6061-T6 aluminium with a Military Specification Hard Coat Type III anodised finish, weighs 0.5 oz (14 g) and is made in the USA. The supplied swivel has a durable 1.25" (32 mm) loop and accepts sling straps up to 1.25".

Why shooters choose the Rail Mount QD Attachment Point

  • Swivel included — the Heavy Duty Push Button QD Sling Swivel comes in the box
  • Mount it anywhere on the rail — the sling point goes where your carry position wants it, not where the rifle put it
  • Rock & Lock one-piece mounting — patented, and quicker to fit than a two-piece clamp
  • Anti-tangle shaping — the sling stays where you put it instead of twisting
  • 6061-T6 aluminium, Type III hard-coat anodised — duty-grade for a part that carries the rifle
  • 1.25" (32 mm) loop — the supplied swivel takes sling straps up to 1.25"

What the Rail Mount QD Attachment Point fits

Fits any MIL-STD-1913 Picatinny rail on AR-15/M4 rifles, including UK straight-pull AR-15 builds — a quad rail, a receiver-mounted section, or a rail section added to an M-LOK handguard. It is a good pairing with a quad-rail handguard that has no built-in sling point, such as the Daniel Defense MK18 RIS II Quad Rail. Everything needed to hang a sling is supplied, including the push-button QD swivel; if you already own a swivel and your handguard is a Daniel Defense M-LOK rail, the cheaper MFR Rail M-LOK QD Sling Mount is the mount on its own.

Product Questions

Is the swivel included?
Yes. This part, 03-021-30029, comes with a Heavy Duty Push Button Quick Detach Sling Swivel. That is the difference between it and the MFR Rail M-LOK QD Sling Mount, 03-021-15136, which is the mount on its own and attaches to M-LOK rather than Picatinny.
What does it mount to?
Any MIL-STD-1913 Picatinny rail, using Daniel Defense's patented Rock & Lock one-piece mounting system. That means a quad rail, a receiver rail, or a Picatinny section added to an M-LOK handguard. It can be positioned anywhere along the rail rather than at a fixed point.
What sling will it take?
The supplied swivel has a 1.25" (32 mm) loop and accepts sling straps up to 1.25" wide, which covers most two-point and convertible rifle slings. Any standard push-button QD swivel will also fit the socket if you want to change it later.
Will it work with a handguard that has no sling point?
That is exactly what it is for. The MK18 RIS II, for example, has no integrated sling swivel attachment point, so a rail-mounted attachment like this one is how you add a forward sling position.
How is it delivered and can it be returned?
Sling mounts are dispatched from the United Kingdom with free tracked UK delivery in 7–10 days, and you'll get tracking by email when it ships. If a part turns out to be the wrong fit, see our returns policy or contact us and we'll help sort it.
