The White Label Armory End Plate is designed to provide a secure and precise interface between the lower receiver and the receiver extension. Ideal for finishing a new lower assembly or replacing a staked factory component, this plate ensures the proper alignment of the buffer tube and provides the necessary retention for the takedown pin detent and spring. Manufactured from high-strength steel and built to meet standard Mil-Spec dimensions, the end plate is engineered for a seamless fit, consistent thickness, and long-term durability under the stresses of recoil. Utilizing a high-quality end plate helps maintain the structural integrity of your stock assembly, allows for proper staking to prevent castle nut loosening, and contributes to the overall mechanical stability of your AR-platform firearm.
