Centurion Arms C4 Chrome Sand Rail Cut Bolt Carrier
*NOTE - Carrier Only
New from Centurion Arms, The C4 Hard Chrome Bolt Carrier with Sand Rail Cuts. Proudly made in house by Centurion Arms, the new Chrome Sand Rail Cut Carrier is designed to not only meet but also exceed the TDP (Technical Data Package) Standards. Due to Centurion producing these in house, they are able to hold the tolerance to their own standards and not being stuck with an "acceptable" range that may just barely meet standards. The new C4 Bolt Carrier features subtle enhancements to enhance overall reliability.
A notable feature of the new C4 Chrome bolt carrier are the Sand Rail Cuts. Similar to the venerable Knight's Armament Sandcutter bolt carrier, the C4 Sand Rail Cut carrier features 5 induvial "sand cuts" on either side added for reliability in harsh conditions.
The carrier itself is precision machined V1 8620 steel that is fully hard-chrome finished and full auto weight. The carrier also includes a Mil-Spec gas key that is chrome lined, phosphate and heat treated per the TDP. The carrier is fastened to the carrier via Grade 8 "OCKS" carrier key screws and properly staked. OCKS carrier key screws are a small but notable feature that we like to see on bolt carriers, featuring 12 individual splines on the head of the screw itself, allowing the metal from the carrier itself to properly engage when staked, making the installation much more secure on one of the most crucial parts of your rifle.
