Alpha Foxtrot AF1911 Romulus MOS | 9mm | 5″ Threaded

The Alpha Foxtrot AF1911 Romulus MOS Adapter is a 9mm Luger, 1911-pattern semi-automatic handgun built for precision and modular optics use. It features a 5-inch threaded match-grade barrel and a direct-mount RMSc footprint optic cut that requires no adapter plate. The pistol ships with both a 17-round and a 20-round magazine and carries a polished DLC black finish over stainless components.

Suggested optic pairing: a Holosun 507K offers a compact footprint and robust feature set for under $1,000 and pairs well with the RMSc cut on this pistol.
