Optimized for AR platforms, American Rifle Company AIR BRACE is the industry's stiffest ultra-light cantilever scope mount. Incredibly light at less than 4 ounces, the AIR BRACE punches far above its weight thanks to its efficient structural design. The cantilevered tubular section of the AIR BRACE maximizes its area moment of inertia (the property that tells us how strong and stiff a beam is) while prioritizing a lightweight and compact design. Unlike competing products in which the scope supports the forward ring more than that ring supports the scope, the forward ring of the AIR BRACE actually supports the scope because its cantilevered section more effectively bears shear stress between the uppermost and lower most portions of the mount-scope structural system. The AIR BRACE was designed to cooperate with the scope to create a structural system that is greater than the sum of its parts.Like the M-BRACE rings and mounts, the AIR BRACE scope clamps exhibit symmetry about the verti...
