The Omega-15 combines a polymer lower and metal upper for a lightweight, AR-15–pattern rifle chambered in 7.62x39. The lower features an integral trigger guard and a flared magwell molded into the receiver for easier magazine insertion. Markings read "E3 ARMS OMEGA-15 MULTI-CAL LHC, AZ" with the serial number plate on the right side.
The 16-inch barrel is threaded and fitted with a muzzle brake/compensator. A long, free-float ventilated handguard with M-LOK–style slots supports accessory attachment, and short top rail sections provide additional mounting points. The slick-side, flat-top upper omits the forward assist but includes a shell deflector and dust cover.
Controls are straightforward with a standard magazine release and a collapsible 6-position stock for length-of-pull adjustment. A rubberized finger-groove pistol grip with palm swells enhances handling. The rifle is configured without sights, allowing the user to set it up to their preference.
This direct impingement, semi-automatic rifle features anodized metal components (e.g., upper/handguard), while the lower receiver is molded polymer, and it offers a 30+1 capacity. It is made in the United States and comes with two curved metal magazines tailored for the 7.62x39 AR pattern.
