Anvil M-Lok Thumb Stop
$14.99
The Crux is a minimal, low-profile M-LOK thumbstop built for control without the bulk. Clean lines, no wasted material, and a consistent index point that keeps your support hand locked in under pressure.
Its subtle rise gives you the leverage to drive the gun, manage recoil, and stay planted through fast stages and awkward barricades — all while keeping your rifle sleek and snag-free.
