Zulisy Otter Micro Red Dot Sight (RMSc/407K/507K Footprint) – 3 MOA Green Dot
The Zulisy Otter is a compact open reflex pistol optic built around the RMSc-pattern footprint (also used by 407K/507K). It features a 3 MOA green dot, a 21mm window with DDRC coating, and recessed tactile brightness controls to help prevent accidental setting changes.
Shake Awake motion sensing is onboard and enters sleep mode after 4 minutes of no movement. This optic uses a side-mounted CR1632 battery for easy swaps without removing the sight. Includes original box, owner’s manual, optic cover, and mounting screws.
