The A3 Industries MFB Folding Pistol Brace is offered in high-strength injection-molded Polymer, or 6061 machined aluminum. The polymer Steady-brace is a hook style minimalist brace that provides the lightest weight and smallest dimensions. The Aluminum Steady-brace is slightly larger and will mount to any buffer tube style mount, just like the popular Tailhook brace. Both Steady-braces ship with a Velcro forearm strap which is optional for use. Steady-braces work equally well on pistol caliber sub-guns as well as rifle caliber pistols. They are lightweight and durable, and a great choice for any folder.
