Centurion Arms Bolt Carrier Hard Chromed with Sand Rail Cuts (Carrier ONLY)

C4 Bolt Carrier, Hard Chromed, with Sand Rail Cuts – Carrier ONLY!

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 properly 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 rail 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.
