NEMO Omen Watchman Rifle, .300 Winchester Magnum, 24-Inch

The NEMO Omen Watchman in .300 Winchester Magnum (brand part no. OMENW-G324CF) is the world’s first viable, reliable, and accurate .300 WM semi-automatic AR-platform rifle, built for ultra long-range precision shooting. NEMO chambers the Watchman’s 24-inch Proof Research carbon fiber barrel in-house for optimal accuracy, and pairs it with NEMO’s own patented recoil reduction system for extremely low felt recoil, along with a recoil-reducing bolt carrier and a nickel boron-coated bolt. The rifle runs a 15-inch 6061 M-LOK modular rail, a NEMO dual-chamber compact muzzle brake, a 4-position adjustable gas system for suppressed or unsuppressed use, titanium takedown and pivot pins, an ambidextrous safety selector, a Geissele SSA-E two-stage trigger, a Magpul MIAD grip, and a Magpul PRS adjustable stock. Among AR-platform rifles in the AR rifles category, the Omen Watchman favors long-range shooters who want magnum-class performance in a semi-automatic platform.
