Accuracy International AXMC Complete 308 Bolt Assembly SFP RH Black 28340BL
Product Description
The Accuracy International AXMC Complete .308 Winchester Bolt Assembly with Small Firing Pin (SFP) in Black (SKU: 28340BL) is a factory OEM drop-in caliber conversion component engineered for right-handed Accuracy International AXMC multi-caliber long-action rifle systems. Designed to enable rapid caliber conversions from magnum platforms down to .308 Win family cartridges, this full bolt assembly includes the complete bolt body, shroud, and Small Firing Pin (SFP) firing assembly.
Featuring a precision-machined 6-lug, 60-degree dynamic throw bolt head and AI's combat-proven leaf spring extractor, the 28340BL ensures ultra-smooth cycling and positive shell extraction under severe firing conditions. The Small Firing Pin (SFP) architecture is optimized for high-pressure precision loads, preventing primer cratering or piercing when shooting small rifle primer brass (such as 6mm Creedmoor, 6.5 Creedmoor, or high-pressure .308 Win loads).
Finished in a low-friction black protective coating, this complete bolt assembly functions as a direct drop-in replacement or conversion unit for AXMC long-action rifles. Used in conjunction with an AXMC magazine well adapter and SA magazine, it provides seamless short-action caliber versatility with factory-certified headspacing.
