Mil-Spec Castle Nut

NOTE: Covid-19, protests, riots and elections has created a strong demand for firearms. We are fulfilling orders as quickly as possible, however you will likely experience longer than usual delivery times due to any delays or back orders that this may have caused. Thank you for your patience.

The Spike’s Tactical Mil-Spec Castle Nut is machined from high carbon chromoly steel for extra strength and is properly heat treated. Our Castle Nut has been machined so that the notches are cut to accept a properly staked latch plate to make sure it doesn’t work its way loose under fire.
