NEMO Mongoose 9mm Pistol | 5.8″ | 35rd
MSRP:$2,699.00
Your Price:$2,512.00
NEMO Mongoose is a lightweight, low-recoil 9mm pistol-caliber carbine with a 5.8″ threaded barrel, SB Tactical FS1913 brace, and included 35-round PMAG for competition and range use.
The NEMO Mongoose is a compact, pistol-caliber carbine built for low recoil and quick handling. It pairs a 5.8-inch threaded steel barrel and short-recoil operating system with an AR-style ergonomics package intended for competition and range/plinking. For optics, a compact red-dot such as the Vortex Sparc AR is a practical match and remains well under $1000, giving a cleared sight picture for close-to-mid-range target work. The package ships with a 35-round PMAG and an SB Tactical FS1913 brace for immediate use on the range.
