Aegis 7.5" Stainless 5.56 NATO AR-15 Pistol Build Kit, M-Lok, 1:7, w/ Magpul BTR Brace

This is a complete pistol-length build kit designed for shooters who want a compact, maneuverable AR-15 platform. The Aegis kit includes everything except the lower receiver: a 7.5-inch stainless steel barrel, upper receiver, bolt carrier group, charging handle, freefloat M-Lok handguard, Magpul BTR brace, and all buffer system components. The 1:7 twist rate stabilizes a wide range of 5.56 NATO ammunition, while the pistol-length gas system keeps the overall profile compact without sacrificing reliability.

Compact Platform with Proven Components

The 7.5-inch barrel length delivers a balance between velocity and handling. Stainless steel construction resists corrosion and extends service life. The freefloat handguard eliminates contact with the barrel, supporting consistent shot placement. The Magpul BTR brace provides secure wrist support while maintaining the pistol configuration.

Pistol-Length Gas System Optimization

The pistol-length gas system is tuned for shorter barrels, cycling reliably without excessive bolt carrier speed. The micro low-profile gas block minimizes weight and profile while maintaining reliable operation. This configuration supports standard 5.56 NATO ammunition without requiring specialized loads.

M-Lok Accessory Ecosystem

The freefloat M-Lok handguard accepts a wide range of tactical accessories and mounting solutions. M-Lok slots run the full length of the handguard, allowing customization based on your specific needs. The handguard is aircraft-grade aluminum for durability without unnecessary weight.

Lower receiver not included. BCG and charging handle are included with this full build kit. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
