AMP M4

AMP M4

Modular Pistol Conversion Chassis with Collapsible Stock

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.
