Unity Tactical FAST Micro-SB Features The Unity Tactical FAST Micro-SB solves a specific problem for shooters running the Aimpoint CompM5s CompM5b or Duty RDS footprint since these mini red dots sit taller than most and standard back-up sights will not co-witness correctly beneath them. The integrated BUIS is machined into the mount at a non-standard 0.95 inch height rather than the typical 1.41 inch front post and Unity ships the correct front post factory installed so there is no guesswork for the end user. Both the front and rear iron sights are fully adjustable giving a true co-witness picture under the optic at the mount s 2.26 inch optical centerline. This height also keeps the sights visible beneath any of Unity s FTC magnifier mounts so the system scales as a shooter adds a magnifier later. Built from 7075-T6 aluminum and finished in a durable Flat Dark Earth anodized coating the FAST Micro-SB is constructed to handle hard use on a duty or competition carbine without the finish breaking down. It comes standard with a 2 cross bolt rail clamp for a secure no-slip attachment to a Picatinny rail and it is also compatible with Unity s FAST QD Lever sold separately for shooters who want quick-detach convenience. The mount s narrow footprint keeps the optic close to the bore axis while still clearing the sight picture for the iron sights beneath it. For anyone running a CompM5s CompM5b or Duty RDS and wanting a mount with built-in back-up sights the FAST Micro-SB is available for sale at GrabAGun.
