Stops the spin on mpx brace - Gear Head Works Tailhook Adapter to Fix Sig Spin Brace

Rock solid attachment for the gear head tail hook adapter. Stops the annoying spin of the factory Sig Brace. When I purchased my MPX copperhead I was disappointed with the brace. It felt spongy and would just spin around and I couldn’t fit my arm in it. The gear head tail hook and this adapter make a perfect pair.
