The Nemo Arms Omen Nitemare OMENNM-S8 delivers 300 Win Mag performance in an ultra-short AR pistol package. Built around an 8" 416R stainless steel threaded barrel with the NEMO DC-1 titanium dual chamber muzzle brake, this limited-edition platform combines serious power with carefully engineered recoil reduction. A billet aluminum receiver set with full-length Picatinny rail, 7" M-LOK handguard, and side-charging handle create a compact, purpose-built system that stays controllable shot after shot.

This model’s adjustable 48-position gas block lets you tune the gun for suppressed or unsuppressed use, while the patented recoil reduction bolt carrier and carbine buffer system help the pistol shoot more like a lighter intermediate-caliber AR. The SB Tactical SBA3 brace and Magpul MIAD grip support stable, comfortable handling for range work, hunting from confined positions, or specialized training where a short overall length is critical. With only 250 units produced, the Omen Nitemare reflects Nemo Arms’ focus on precision engineering and innovative big-bore AR design.
