The Daniel Defense Micro Mount is a Rock & Lock optic mount for Aimpoint Micro-footprint red dots, giving absolute or lower 1/3 co-witness on a flat-top AR-15 upper receiver.
Both heights in one box — the lower 1/3 spacer is included, so you decide at the bench rather than at the checkout.
Most micro red dot mounts make you choose a height before you have ever looked through the optic on your own rifle. This one does not: it gives absolute or a lower 1/3 co-witness with your backup iron sights, and the magnesium alloy spacer that raises it is supplied. Fit it, shoulder the rifle, and change your mind if you want to.
A recoil lug interface sits between the mount and the optic, so the red dot is located positively rather than relying on clamping friction alone, and the body is snag-free and reversible. Attachment is Daniel Defense's patented Rock & Lock system onto the receiver rail. The mount is precision CNC machined from aircraft-grade 6061-T6 aluminium and Military Specification Type III hard-coat anodised, weighs 1.5–1.8 oz (43–51 g) depending on configuration, and is made in the USA.
On a UK straight-pull AR-15 the optic is usually the most expensive thing on the rifle, and the mount is what decides whether its zero survives being taken in and out of a slip. A positively located mount earns its place.
Fits red dots on the Aimpoint Micro footprint — Aimpoint Micro R-1, H-1, H-2, T-1 and T-2, Vortex Sparc I and II, Primary Arms Micro Dot and Advanced Micro Dot, and the Holosun Technologies HS403, plus other optics with the same mounting interface. It mounts to a flat-top AR-15 upper receiver rail, including UK straight-pull AR-15 builds. Use it without the spacer for absolute co-witness with standard AR-15 iron sights, or with the supplied magnesium alloy spacer for a lower 1/3 co-witness. Check your optic's footprint rather than its brand — a dot on a different footprint will not sit on this mount.

Anything on the Aimpoint Micro footprint. Daniel Defense lists the Aimpoint Micro R-1, H-1, H-2, T-1 and T-2, the Vortex Sparc I and II, the Primary Arms Micro Dot and Advanced Micro Dot, and the Holosun HS403, plus other optics with the same mounting interface. Check the footprint rather than the brand.
Both of the usual ones. Used on its own it gives an absolute co-witness with standard AR-15 iron sights; with the supplied magnesium alloy spacer fitted it gives a lower 1/3 co-witness. The spacer is included, so you are not committing to a height when you order.
Through a recoil lug interface between the mount and the optic, so the dot is positively located rather than held by clamping force alone. The mount itself attaches to the receiver rail with Daniel Defense's patented Rock & Lock system.
That is the point of a co-witness mount — the dot sits so that your existing front and rear irons line up either through the middle of the window (absolute) or in the lower third of it. It mounts to a flat-top upper receiver rail, so you need that rail free where the mount sits.
