Frequently Asked Questions

What are the key features of the Sharps Rifle Company Xtreme Performance Bolt Carrier Group?

The SRC BCG features a Diamond-Like Carbon (DLC) coating for enhanced durability and easy cleaning. It also includes lightning cuts, reduced carrier-to-receiver contact surfaces for smoother operation, and unique lug geometry designed for efficiency.

How easy is the Sharps Rifle Company DLC bolt carrier group to clean?

The DLC coating makes the SRC BCG exceptionally easy to clean. Carbon fouling wipes off with minimal effort using a damp cloth and a light solvent, rivaling the cleaning ease of nickel boron or chrome finishes.

What are the gas system recommendations for using the SRC DLC BCG?

For suppressed 5.56 NATO AR-15s, a mid-length gas system is recommended with the SRC DLC BCG to manage gas blowback effectively. Carbine-length systems may result in excessive gas, especially when suppressed.

Does the SRC DLC bolt carrier group work in all AR-15 platforms?

While generally reliable across many AR-15 platforms, the SRC DLC BCG has shown compatibility issues with very short-barreled pistol AR-15s. These platforms may experience overgassing and reliability problems.
