B&T USW-G20 Conversion Kit for Glock 20/21 – Complete Pistol-to-Carbine System

The B&T USW-G20 Conversion Kit transforms a Glock 20 or Glock 21 into a compact, shoulder-fired platform with integrated stabilization and enhanced capability. This Swiss-engineered system includes a lightweight chassis that houses the pistol, a folding stock for improved control, and an integrated rail system for mounting optics and accessories. Designed for professionals and serious shooters who need maximum versatility from their large-frame Glock pistols.

The conversion kit is precision-machined from aircraft-grade aluminum with a hard-anodized finish. It accepts standard Glock 20/21 magazines and maintains full compatibility with factory controls. The folding stock provides a stable shooting platform while keeping the overall package compact for transport. Optics-ready top rail allows for mounting of red dots or other sighting systems. Kit includes chassis assembly, folding stock, mounting hardware, and Allen keys for installation. Does not include the Glock pistol, magazines, or optics.
