Craddock Precision HD ARC Bolt
The latest evolution bringing ARC's full potential to your AR.
The Craddock Precision HD ARC Bolt was engineered specifically around the demands of the ARC family of cartridges. Built for shooters pushing modern high-performance loads, this enhanced design features reinforced geometry, improved lug design, and increased strength in critical stress areas to improve durability and long-term reliability under heavy use.
Designed to support pressures up to 62,000 PSI, the HD ARC Bolt was developed for serious shooters who expect more from their rifles — whether that means extended range sessions, competition use, or hard field conditions.
During development and testing, we pushed the HD ARC Bolt well beyond its 62,000 PSI operating specification to validate the strength and durability of the design. 62,000 PSI remains the maximum recommended operating pressure. Those tests are part of how we validate the bolt — not an invitation to exceed the published limit.
The HD ARC Bolt is manufactured using carefully selected, high-quality materials with tightly controlled and verified heat-treatment processes. Material and heat-treat specifications are controlled throughout manufacturing to provide consistent strength, durability, and performance from bolt to bolt.
Features
- Enhanced Type II 6.5 Grendel bolt geometry
-
Compatible with 6.5 Grendel and the entire ARC family
- Reinforced cam pin hole web to increase strength in a critical stress area
- Improved lug geometry to reduce wear and provide smoother locking and unlocking
-
Tightly controlled ejector dimensions to help minimize case-head extrusion and brass smear
- DLC coated for increased surface hardness, wear resistance, and lubricity while maintaining a tough core
- Compatible with Mil-Spec bolt components for straightforward integration into existing systems
- Precision manufactured and inspected for consistent fit, function, and performance
The result is a stronger, more refined ARC-ready bolt built to handle the demands of modern cartridges and hard-use applications.
Built for the shooters who refuse to baby their gear.
We originally called it the “Indestructabolt", but our lawyers said that would only dare people to try harder.
Designed and intended for use in AR-15, M16, and M4 platforms, may not work with other rifles that utilize M16 compatible bolts.
