The Omni Hybrid lower is reinforced polymer with a visible metal insert at the buffer/receiver extension interface. The lower is marked "OMNI HYBRID MULTI-CAL," and the receiver displays "US Patent 9068786." This construction keeps weight down while maintaining critical-strength reinforcement at the rear of the receiver.
The pistol uses a 7.5 inch threaded barrel capped with a birdcage (three-slot) flash hider. It operates via a semi-automatic, direct impingement system with a rotating bolt and includes a manual safety selector. It accepts AR-15/STANAG pattern magazines and has a 30+1 capacity.
The upper is a flat-top design and includes an ejection port cover. The aluminum free-float KeyMod handguard features a continuous top Picatinny rail. No sights are installed.
Ergonomics include a Magpul MOE-K2+ pistol grip and a skeletonized polymer stabilizing brace with a Velcro strap. The two-tone OD green/black finish gives the pistol a distinctive look, and it is made in the USA.
