Installing AR-15 detents can be challenging and is frequently the most frustrating aspect of assembling an AR-15. However, the pivot pin detent tool simplifies the installation process, significantly reducing the likelihood of the detent slipping out and becoming lost in the work area. 4140 alloy steel undergoes heat treatment to achieve optimal hardness and durability The QPQ process has been completed to apply a rust-preventative coating, enhancing the material's corrosion resistance and surface durability
