E3 Arms Omega-15 Gen II 5.56 NATO AR-15 Rifle with Custom Polymer Lower, 16" Barrel & Daniel Defense Sights
The E3 Arms Omega-15 Gen II combines a lightweight glass-filled nylon lower with proven AR-15 components to deliver a distinctive, user-focused carbine. This second-generation polymer design integrates the buffer tube, reducing parts count and weight while addressing strength concerns seen in earlier polymer receivers. Factory nickel-boron coating on the bolt-carrier group, a tri-port stainless muzzle brake, and custom hand-painted graphics give this rifle functional upgrades and visual character that set it apart from standard builds.

Gen II Omega-15 lowers are molded from glass-filled nylon-6, offering corrosion resistance and weight savings over aluminum while integrating the buffer extension to eliminate castle-nut loosening. The 12.5" length of pull fixed stock keeps the rifle compact yet comfortable.
A nickel-boron coated bolt-carrier group enhances lubricity and simplifies cleaning. Paired with the direct-impingement action, it supports reliable cycling with both 5.56 NATO and .223 Remington ammunition.
The tri-port stainless steel muzzle brake effectively mitigates recoil and muzzle rise, allowing for faster follow-up shots. Daniel Defense fixed iron sights provide a durable, zero-retaining aiming solution, and the polymer M-LOK handguard accepts accessories while keeping overall weight low.
Custom, hand-painted 'E3 Arms' and 'OMEGA' markings, along with a red-lips cartridge graphic on the mag-well, give this rifle a one-of-a-kind appearance appreciated by shooters who value individuality in their gear.
