Aero M4E1 - Magwell

Built for speed and reliability, this magwell is purpose-engineered for the Aero Precision M4E1 lower. Its compact form increases the magwell funnel size for smoother, vacuum-like reloads while adding no unnecessary bulk or complexity. Designed to stay out of your way, it supports fast reloads and clean manipulations without interfering with your manual of arms. Crafted from a single piece of rugged nylon, this magwell delivers a rock-solid upgrade in a lightweight package.

Key Features:
Streamlined Profile – Compact, smooth-edged design that won’t catch on gear, gloves, or kit.
Enhanced Funnel Size – Expands the magwell opening for vacuum-like reloads and faster magazine insertion.
Uninterrupted Handling – Contoured to avoid interference during reloads, manipulations, and transitions.
Minimal Hardware, Maximum Reliability – Uses a single M2 screw (requires 1.5 mm Allen wrench) for a clean install with virtually no failure risks.
