The Strike Industries SIG MPX/MCX Stabilizer (part no. SI-STAB-MPX/MCX) is a shooting brace built specifically for the SIG Sauer MCX and MPX pistol platforms, sold by Strike Industries. It clamps onto the MCX/MPX-pattern receiver extension, giving these large-format pistols a forearm brace point to improve control and stability during one-handed shooting. Because it is purpose-built for the MCX/MPX geometry rather than a universal mil-spec buffer tube, it is sized to seat correctly on these specific SIG platforms without needing an adapter. This kind of add-on brace is popular with MCX/MPX pistol owners who want a more stable shooting platform without converting the gun to an SBR. It is a direct, platform-specific stability upgrade.
