Frequently Asked Questions

What makes the E2 Armory bolt carrier group stand out?

The E2 Armory BCG features a micro-polished titanium nitride coating applied via PVD, offering superior hardness, thermal stability, and lubricity. It's constructed from 9310 alloy and undergoes rigorous HP and MPI testing for enhanced reliability and durability.

What are the benefits of titanium nitride coating on a BCG?

Titanium nitride coating provides excellent abrasion resistance, corrosion protection, extreme temperature resistance, high wear resistance, and increased lubricity. This results in a smoother operation, longer lifespan, and better performance under demanding conditions.

How is the E2 Armory BCG tested for quality?

The BCG is High Pressure (HP) tested by firing a round at elevated pressure to ensure structural integrity. It also undergoes Magnetic Particle Inspection (MPI) to detect any microscopic cracks or fractures that could compromise its performance over time.

What materials are used in the E2 Armory BCG?

The main bolt carrier is made from a 9310 alloy. The extractor is machined from 4140 tool steel alloy, and the extractor pin is precision ground from AMS 6440 bearing grade steel, all contributing to the BCG's overall robustness.
