1/2 Stud - 3.620 Long Broached

The 1/2 Stud - 3.620 Long Broached is a precision fastener component engineered for AR-platform upper receiver assemblies and custom tactical builds. This broached stud serves as a critical structural element in firearm receivers where exact tolerances and material integrity are non-negotiable. Whether you're building a duty rifle, precision competition platform, or maintaining issued military hardware, this component ensures the mechanical reliability that professionals depend on when lives or missions are at stake.

ARP's broached studs are manufactured to exacting specifications using hardened steel, designed to withstand repeated cycling and the stresses of high-pressure rifle operation. The broaching process cuts precise internal geometry that allows for positive engagement and alignment during assembly, eliminating the dimensional drift that can occur with standard fasteners. At 3.620 inches in length, this stud accommodates the geometry demands of modern AR receiver designs while the 1/2-inch diameter provides adequate load-bearing surface for critical connection points. The compact 0.17-pound weight reflects the efficiency of the design—no unnecessary material, only what's required for durability and function.

This component is essential for gunsmiths, armorer-level technicians, and professional builders who demand component-level reliability in tactical systems. Installation requires proper receiver-specific tooling and understanding of AR assembly sequences; this is not a field-swap part but rather a core structural element for precision builds or replacement during professional maintenance. Compatible with standard AR-15 and AR-10 upper receiver platforms where OEM specifications call for this exact stud geometry, it provides the dimensional accuracy necessary for zero retention and consistent cycling under duty conditions.
