This customized Aero Precision M4E1 delivers versatile .223 Wylde performance in a feature-rich AR-15 package.

What’s Included
- Aero Precision M4E1 .223 Wylde rifle
- (1) 30-round Magpul PMAG polymer magazine
The heart of this build is Aero Precision’s M4E1 receiver set, forged from 7075-T6 aluminum and finished in black hard-coat anodizing. The upper integrates an enlarged trigger guard and threaded bolt-catch pin, streamlining assembly and improving durability.
The .223 Wylde chamber safely fires both .223 Remington and 5.56 NATO, making ammunition choice simple. A 16.25-inch barrel meets length requirements thanks to a pinned and welded multi-port brake that cuts recoil and flash while keeping the overall profile legal.
Up front, a lightweight STNGR 15-inch aluminum handguard offers a full-length Picatinny top rail and M-LOK slots at every clock position for optics, lights, or grips. Free-float construction helps maintain accuracy and dissipates heat.
Controls are user-focused: an ambidextrous extended-latch charging handle speeds manipulation, while a Magpul MOE polymer pistol grip provides a familiar, ergonomic angle. The Ruger 6-position collapsible stock—finished in flat dark earth—lets shooters tune a 12.25-inch length of pull to fit body armor or range gear.
Direct-impingement operation, a threaded muzzle, and compatibility with standard AR-15 accessories make this custom M4E1 a straightforward choice for shooters seeking a ready-to-run platform with thoughtful upgrades.
