The Sig Sauer Romeo5 Gen II Compact is a 1x20mm red dot sight for the modern sporting rifle (MSR / AR-15 platform). It includes an interchangeable mount system — a Picatinny riser for AR absolute co-witness plus a low mount for a lower carbine height.

Features:

• 1x magnification, 20mm objective, parallax-free
• 2 MOA green dot reticle
• 12 brightness settings (10 daylight + 2 night-vision compatible)
• MOTAC motion-activated illumination — wakes on movement, powers down when idle
• CR2032 battery with long runtime via MOTAC
• IPX7 waterproof and fog-proof
• Includes a Picatinny absolute co-witness riser and a low mount

A classic AR / MSR red dot — run the riser for absolute co-witness or swap to the low mount for a lower-profile carbine setup.
