Breek Arms is dedicated to using the right components for the most reliable functioning AR builds. The most important part in your AR15 is the bolt carrier group. This is why we’ve found a superior BCG with a high quality low friction nitride coating that protects against corrosion and heat that an AR15 endures over time. This model is chrome lined on the inside of the carrier where the bolt actuates, so it helps improve function and reduce wear on the bolt.
Each bolt carrier group undergoes a magnetic particle inspection (MPI) to ensure you get a simple, no frill BCG that provides you with the reliability and performance you expect from a high end AR15. This BCG is rated for full-auto use, so you can be sure it will perform well in your semi-auto builds, and even in a full-auto build if you are lucky enough to have that opportunity.
