Daniel Defense just announced an upgrade to their Aimpoint® Micro Mount. The original was already a simple, effective, and durable mount for the Aimpoint Micro T, H and R optics, but the update gives you the option of an absolute co-witness. They didn’t mess with anything else.

The Daniel Defense Aimpoint Micro Mount has been proven to be one of the most durable and light weight mounts available.

  • Absolute or lower 1/3rd co-witness
  • Recoil lug interface between mount and optic
  • Snag free and reversible
  • Patented Rock & Lock® attachment system
  • Light weight


  • Precision CNC machined from aircraft-grade 6061-T6 aluminum
  • Military specification type-III hard-coat anodized
  • 1.5 ounce or 1.8 ounce with lower 1/3rd spacer

The mount bolts on to a 1913 rail with a pair of screws. The mount is simple and light since there’s no quick-release BS. The $79 mount is made from 6061-T1 aluminum and weighs 1.5 ounces or 1.8 ounces with the magnesium lower-third co-witness spacer.

The SLiM Rail™ (Slim, Lightweight, Modular) from Daniel Defense utilizes the KeyMod accessory-attachment system for incredible weight savings as well as superior cooling, ergonomics, and modularity while maintaining the strength and durability expected from Daniel Defense. KeyMod is a recoil-resistant, two-part, direct-attachment method for accessories that offers outstanding “return-to-zero” when accessories are removed and reinstalled.

The SLiM Rail™ features the battle-proven “Bolt-Up System,” which provides modern flat-top upper receivers with a free-floating, continuous, uninterrupted upper rail platform and allows for simplified alignment to the host weapon’s upper receiver.   Ambidextrous sling swivel-attachment points are integrated into both the left and right side rails at one and 11 o’clock positions. The SLiM Rail™ can be used with a low-profile gas block on pistol, carbine, or mid-length gas systems.


  • Light weight free-floating barrel design
  • Steel barrel nut
  • Uninterrupted mil-spec 1913 Picatinny upper rail
  • KeyMod attachment at three, six, and nine o’clock positions
