Aero Precision machines the M4E1 lower from forged 7075-T6 aluminum and integrates an enlarged trigger guard plus a flared magazine well for faster reloads. The threaded bolt-catch pin design simplifies maintenance and adds strength.
The 16-inch 4150 CMV barrel is chrome-moly vanadium steel, threaded 1/2x28, and paired with a carbine-length gas system anchored by an A2 front sight base. This setup balances reliability with reduced recoil impulse.
Magpul’s MOE carbine-length handguard, MOE pistol grip, and six-position collapsible stock keep weight down while adding proven ergonomics. The rifle retains a fixed A2 front sight and a flat-top Picatinny upper, giving you the option to run irons or optics.
The lower’s CAL MULTI marking allows easy caliber changes by swapping uppers. Finished in matte black hard-coat anodizing, the matched receivers maintain tight tolerances and consistent color.
