Centurion Arms Complete Sandcutter BCG w/ V2 Chrome Bolt

C4 Bolt Carrier, Hard Chromed, Sand Cutter, with V2 Bolt

Proudly American made in house, our new carrier will set the new standard for AR rifle bolt carrier groups. Experienced operators know the single most critical AR spare part is a spare bolt carrier group and ours have been subtly redesigned to enhance overall reliability. All critical dimensions and specifications meet or exceed the Technical Data Package requirements.

Fully hard-chrome finished, the V1 8620 steel, full-auto weight carrier includes a proper machined Mil-Spec chromed gas key that is chrome lined and heat treated per the TDP and is secured to the carrier via OCKS and properly staked during final inspection.

Sand cuts are added for increased reliability in harsh conditions.

These precisely machined, finished and hardened parts will ensure long term proper gas system functioning and reliability and have been engineered based on feedback from real world end users.

*Initial batches were released with staked chrome lined phosphated key
**Early batches of carriers included a small hole near the firing pin retaining pin hole that was originally inteded for a captive pin but we weren’t happy with the strength and decided not to do them. The hole now has no purpose, but also won’t affect function in any way.
