Eagle Arms Eagle 15 5.56 NATO AR-15 Rifle - TRADE IN

The Eagle Arms E-15 is a straightforward mil-spec AR-15 in 5.56 NATO — flat-top upper with a Picatinny rail section for optics, a fixed front sight tower, a flip-up rear sight that folds clear when an optic is mounted, and a standard carbine handguard that keeps the profile slim and the rifle light.

The Eagle Arms E-15 is a semi-automatic 5.56 NATO AR-15 pattern rifle featuring a flat-top upper with a receiver-length Picatinny rail section, a fixed front sight tower, a flip-up rear sight, an M4-style polymer carbine handguard, an A2 flash hider, and a six-position collapsible stock.

The E-15 is built around a simple, proven configuration that prioritizes reliability and practicality over complexity. The flat-top upper provides a Picatinny rail section for mounting optics, red dots, or backup sights at any position along the receiver, while the fixed front sight tower delivers a permanent, always-available front aiming reference that requires no deployment and cannot be accidentally left in the down position when the rifle is needed. The flip-up rear sight folds flat against the rail when an optic is mounted — keeping the mounting surface clear — and deploys immediately when a backup iron sight picture is required, pairing with the front post for a complete aiming system without removing or modifying any components. The M4-style polymer carbine handguard keeps the overall rifle profile slim, light, and manageable without the bulk and weight of a free-float rail system, appropriate for a practical-use rifle that doesn't need four-sided accessory real estate. The 5.56 NATO chamber accepts both mil-spec 5.56 and commercial .223 Remington loads without modification, and the six-position collapsible stock adjusts for different builds and shooting positions.
