ET Arms Omega-15 AR-15 Style .223 Remington 5.56 NATO Blue/Black Rifle

The ET Arms Omega-15 is a lightweight AR-15 style rifle chambered in .223 Remington and 5.56 NATO. Its polymer receivers use carbon fiber reinforcement in the lower receiver and metal inserts in the upper receiver for a balance of reduced weight, strength, and rigidity. The 16-inch barrel features a 1:8 twist rate suited to a broad range of bullet weights, including heavier 5.56 NATO loads, and is capped with an A2 flash hider. A 15-inch free-float M-LOK handguard provides mounting space for accessories, while the receiver rail accommodates a compatible optic. The rifle includes adjustable flip-up front and rear sights, an ATI SR-1 Deluxe adjustable stock, an overmolded grip, a Nano Composite Safety trigger, and one Amend2 30-round magazine.
