NEMO Omen Watchman | .300 Win Mag | 24in Carbon | 14rd

The NEMO Omen Watchman is a semi-automatic .300 Winchester Magnum AR-style platform built for extended-range precision. Its 24-inch Proof Research carbon fiber barrel and NEMO’s patented recoil-reduction system are engineered to reduce felt recoil and support accurate follow-up shots. Ergonomics and component quality (billet receivers, Magpul PRS stock, Geissele trigger) put this rifle in the precision-oriented AR segment. A Vortex Viper PST Gen II 5-25×50 (priced under $1,000) is a suitable optic choice for pairing with this platform for extended-range work.
