Specifications

Manufacturer: CMMG

From the manufacturer

CMMG Inc Bolt MK3. The CMMG Bolt is a dual-stacking cold hammer-forged and button-head bolt that will withstand extreme chamber pressures and is reusable. With the same mandrel-threaded design as all CMMG bolts this cold hammer-action bolt is a cold-hammer-driven high-capacity load-carrying powerhouse making it a great choice for anyone needing an extra bolt. With its near symmetrical design the CMMG Bolt requires less trigger finger travel and trigger finger tension to fully seat the bolt while its oversized pivot pin makes it easy to grab and fire.
