Sig Sauer ROMEO1PRO 1x30mm Open Reflex Red Dot Sight (ROMEO1PRO (SIG Pro) Footprint)
The Sig Sauer ROMEO1PRO is a miniature open-reflex red dot built around a 30mm class window and a molded glass aspheric lens with high-performance coatings for light transmission and low distortion. It features an aircraft-grade CNC aluminum housing, MOTAC (motion-activated illumination), and a TruHold lockless zeroing system designed to stay put under handgun recoil.
This optic uses a top-loading CR1632 battery with 12 illumination settings (10 daytime/2 night vision) and is rated waterproof to IPX-7. Included with this unit: mounting screws and a protective shroud.
