One chassis, three adapters, total platform flexibility.
The AMP M4 is FAB Defense's modular pistol conversion chassis, built around three interchangeable adapters that let a single chassis serve a wide range of handgun models. The open-top design keeps slide-mounted optics (MOS-pattern) accessible and unobstructed.
The M4 configuration adds a six-position collapsible stock built on FAB Defense's combat-proven GL-Core S buttstock — the same platform trusted across our AK and AR product lines.
