The Vang Comp System (VCS), designed by gunsmith Hans J. Vang.

All VCS magazine tube extensions are precision machined from solid steel bar stock and finished with a durable non-reflective black oxide. They also feature a unique sling attachment point that is reversible to accommodate right or left-handed shooters. Every magazine tube extension comes with a longer magazine tube spring to ensure proper feeding.
