Ring Gear Bolt Kit ARP Drilled

The Ring Gear Bolt Kit ARP Drilled is a precision quick-change fastener system designed for AR-pattern rifle builds and component assembly in professional tactical and military applications. This 12-piece chromoly bolt kit addresses the critical need for repeatable, reliable fastening in upper and lower receiver assemblies where precision tolerances and durability directly impact firearm reliability. Whether you're building a precision rifle, servicing existing platforms, or maintaining a professional armory, consistent bolt specifications eliminate variable points of failure.

Manufactured from chromoly steel with black oxide finish, the Ring Gear Bolt Kit ARP Drilled features 3/8-24 thread pitch and 1.125-inch length, optimized for tiger quick-change systems commonly found in modular rifle platforms. The 12-point head design distributes load more evenly across fastening points than traditional hex configurations, reducing stress concentration and improving clamping force consistency. Black oxide coating provides corrosion resistance and reduced glare in tactical environments while maintaining dimensional stability across temperature and humidity variations. The drilled specification allows integration with safety pins or retention mechanisms, adding an extra layer of security critical in professional operations.

This bolt kit serves armors, gunsmiths, military support personnel, and serious builders maintaining AR-pattern rifles in duty or training roles. The 12-count packaging ensures you have spares for component changes, maintenance cycles, or multi-platform builds without interrupting operational readiness. Compatibility with tiger quick-change systems makes these bolts ideal for modular upper and lower assemblies, barrel extensions, and rail systems requiring consistent fastening. Weighing just 0.7 pounds, the entire set remains portable for field maintenance kits or shop inventory without adding significant burden to gear loads.
