The fast micro mount features built-in standard height back up iron sights that keep weapons uncluttered, without reducing capability.Both front and rear buis are completely adjustable for windage and elevation.The front sight post can be removed so that the rear buis aperture can be used with a traditional front sight such as our fusion fixed or folding sights (if present), creating a more conventional sight radius.However, the built in front/rear buis is perfect for backup on super short pdw/smg platforms where rail space is critical for mounting lights and lasers.Designed for aimpoint micro (h1, h2, t1, t2, compm5) and other optics with aimpoint micro footprint, such as those found on many sig sauer, holosun, primary arms, and vortex optics platforms.Note: does not fit aimpoint comp m5s or m5b.Length: 2.2"Model: Fast MicroMaterial: 7075 T6 AluminumPieces: 1Mount Type: Rail Clamp/Picatinny Rail/Micro Pattern FootprintMount Height: 2.26"
