Overview

This oversized magazine well is designed to make magazine changes faster and more intuitive on AR-15/M16 platforms, especially when maintaining focus on the target matters.

The black matte finish blends with most AR-15 setups, and the polycarbonate construction gives it a durable, purpose-built feel without adding unnecessary bulk.
