Sig Sauer Romeo-MSR Red Dot 1x20mm 2 MOA | SORMSR101

The Sig Sauer Romeo-MSR is a compact non-magnified red dot optic built for MSR-style platforms and carbines. It provides a 1x viewing window over a 2 MOA dot and is designed for sealed, all-weather operation with an IPX7 waterproof rating. The sight uses a see-through riser mount for convenient co-witness and runs on a readily available CR2032 battery with an extended runtime.
