1/2 Stud - 3.250 Long Broached

The 1/2 Stud - 3.250 Long Broached is a precision-engineered fastener designed for AR platform builds and tactical rifle assembly applications. This chromoly steel component serves as a critical connection point in bolt carrier group construction, upper receiver assembly, or custom firearm manufacturing. Builders and armorers rely on properly specified studs to ensure consistent headspace, reliable cycling, and repeatable performance across high-round-count builds.

Manufactured from chromoly steel and finished in black oxide, this broached stud accommodates both 1/2-13 and 1/2-20 thread pitches, offering compatibility across multiple build specifications and receiver designs. The broached construction—a precision cutting method that shapes the stud's geometry in a single pass—eliminates stress concentrations and delivers uniform material consistency. At 3.25 inches in length and weighing just 0.16 pounds, the compact profile integrates seamlessly into tight receiver geometries without dimensional interference. Black oxide coating provides corrosion resistance and a professional mil-spec appearance while maintaining dimensional tolerances required for precision fit.

This stud benefits gunsmiths, AR builders, and military/law enforcement armorer shops performing upper receiver rebuilds, bolt carrier group servicing, or complete platform manufacturing. Installation requires standard machine shop equipment or professional assembly—ensure proper torque specifications and thread-locking compound application per manufacturer guidelines. Its universal design accommodates both milspec and commercial receiver patterns, making it a versatile choice for standardized builds, replacements, or spare parts inventory across mixed-platform operations.
