Frequently Asked Questions

What makes the Cox Arms USA Combat BCG stand out from other bolt carrier groups?

The Combat BCG features proprietary machining, a micro-polished finish, a 3/10ths electroless nickel plating, and a hybrid DLC SP4 coating, which Cox Arms USA claims is the hardest and slickest available in the civilian market. It also includes cryo-treated internal components and a robustly staked gas key.

What is the purpose of the SP4 coating on the Combat BCG?

The SP4 coating is a hybrid DLC (Diamond-Like Carbon) coating designed to provide exceptional hardness and slickness. This reduces friction and wear, contributing to the BCG's durability and reliability, especially in demanding operational environments.

Does the advanced coating on the Combat BCG eliminate the need for lubrication?

No, Cox Arms USA explicitly states that lubrication is still absolutely essential for the Combat BCG. While the coatings enhance slickness and durability, proper lubrication is crucial for optimal function and to prevent premature wear.

What is the price and availability of the Cox Arms USA Combat BCG?

The Combat BCG retails for $289. It is available through Cox Arms USA dealers and can also be ordered directly from Cox Arms USA via their website or by phone, with shipping expected to commence shortly after SHOT Show 2023.
